Appeal from the United States District Court for the Southern District of Florida ________________________
(November 7, 2012)
Before WILSON, PRYOR and MARTIN, Circuit Judges. Case: 10-15327 Date Filed: 11/07/2012 Page: 2 of 21
MARTIN, Circuit Judge:
Mr. Stephen Horrillo, as the personal representative of the Estate of Ms.
Margaret Horrillo, appeals the district court’s grant of summary judgment in favor
of Cook Incorporated in this product liability action.
I.
On May 31, 2007, Dr. Michael Rush performed an angioplasty and inserted
a Formula 418 biliary stent into Ms. Horrillo’s renal artery to treat her arterial
stenosis.1 The surgery was performed at Holy Cross Hospital in Fort Lauderdale,
Florida. Although Dr. Rush considered the procedure a success in the hours
immediately after surgery, Ms. Horrillo suffered a non-hemorrhagic stroke within
twenty-four hours of the procedure, which resulted in serious injuries.
The Formula 418 biliary stent that Dr. Rush used was manufactured by
Cook Incorporated. The Food and Drug Administration (FDA) had approved the
stent for biliary use, but had not approved its use in renal arteries. This being the
case, Cook included the following disclosures in the stent’s instructions for use.
First, it stated that the device was “intended for use in palliation of malignant
neoplasms in the biliary tree,” which is to say, treatment for cancer in the bile

ducts. Second, under a heading entitled, “WARNINGS,” the instructions for use
cautioned that “[t]he safety and effectiveness of this device for use in the vascular
system have not been established.”2
Depositions in this case suggest that it was common knowledge that biliary
stents, like Cook’s, were frequently used “off-label” to facilitate peripheral
circulation, including in the renal arteries. In fact, Dr. Rush stated during his
deposition that he had performed many angioplasty procedures and had previously
used the Formula 418 biliary stent to treat arterial stenosis, to the point where he
felt experienced with its off-label use.
In February 2007, the FDA contacted various medical device manufacturers,
including Cook, to attend a meeting because of the extensive off-label use of
biliary stents and the high rate of bad medical outcomes reported in connection
with that off-label use. The FDA cited complications including “air embolism,
seizure, stroke and death.” For Cook, forty percent of the adverse medical
incidents associated with its Formula 418 biliary stent originated in off-label use.
The FDA held the meeting with the stent manufacturers, including Cook, on
March 12, 2007. On October 18, 2007, Cook sent a letter to Holy Cross
2 Cook eventually filed an application with the FDA to approve the use of the Formula 418 stent in renal arteries, but the application had not been approved at the time this lawsuit was filed.

Hospital—where Dr. Rush had performed Ms. Horrillo’s surgery on May 31,
2007—warning of the risks associated with the off-label use of the biliary stent.
Among the risks listed in the October 2007 letter was stroke.
II.
In January 2008, Ms. Horrillo filed a complaint against Cook in Florida
state court, asserting claims for negligence, strict liability, and breach of warranty
under Florida law. Cook removed the case to the District Court for the Southern
District of Florida on the basis of diversity jurisdiction.
In August 2010, Cook filed a motion for summary judgment arguing that
Ms. Horrillo had failed to demonstrate that Cook was the proximate cause of the
harm she suffered. Relying on the learned intermediary doctrine, Cook argued
that because Dr. Rush was aware of the risks associated with the angioplasty
procedure, Ms. Horrillo could not demonstrate that Dr. Rush would not have used
the stent if either he or Horrillo had been warned by the manufacturer of its risks.
In support of this argument, Cook cited Dr. Rush’s deposition, as well as an
affidavit that the doctor filed on behalf of Cook. In his deposition, Dr. Rush
explained:
I didn’t think there was anything that I would be doing in her renal artery that might cause increased or an excessive risk of a stroke. The things that I might do to cause her to have a stroke, potentially,
4 Case: 10-15327 Date Filed: 11/07/2012 Page: 5 of 21
might be if I shut the renal artery down, occluded it completely, if she had a hypertensive spike, that is, a spike in high blood pressure, and she would bleed into her brain.
That’s a possibility but a remote risk, and I felt that any type of risk like that was worth the possible benefit of the procedure.
In his affidavit, Dr. Rush averred that he elected to use the device as a matter of
his own clinical judgment. The magistrate judge granted Cook’s motion.3 The
magistrate judge reasoned that Dr. Rush was “fully aware that [the] stent was not
approved for renal use; he was familiar with the risks associated with the device’s
use including stroke, which he believed to be ‘remote’; [and] he was immensely
experienced in performing renal stenosis surgeries . . . .” Based on this, the judge
held that the learned intermediary doctrine applied as a matter of law. Ms.
Horrillo appealed the grant of summary judgment. After filing her notice of
appeal, Ms. Horrillo passed away. We have since granted a motion to substitute
her son, Mr. Stephen Horrillo, as the personal representative of her estate,
pursuant to Federal Rule of Appellate Procedure 43(a)(1).
III.
This Court reviews de novo a grant of summary judgment. Fitzpatrick v.
City of Atlanta, 2 F.3d 1112, 1117 (11th Cir. 1993). Summary judgment is proper
3 The parties consented to the exercise of jurisdiction by a magistrate judge, pursuant to 28 U.S.C. § 636.
5 Case: 10-15327 Date Filed: 11/07/2012 Page: 6 of 21
only if there is no genuine issue as to any material fact and the moving party is
entitled to judgment as a matter of law. Fed. R. Civ. P. 56(c). “In reviewing a
grant of summary judgment, we resolve all ambiguities and draw reasonable
factual inferences from the evidence in the non-movant’s favor.” Layton v. DHL
Express (USA), Inc., 686 F.3d 1172, 1175 (11th Cir. 2012).
Under Florida law, a manufacturer of a “dangerous commodity,” such as a
prescription drug or a medical device, has a duty to warn consumers of the known
risks of using its product. Buckner v. Allergan Pharms., Inc., 400 So. 2d 820, 822
(Fla. 5th DCA 1981). Failure to provide that warning may render the
manufacturer strictly liable for any resulting harm. Id. at 822–23. However, in the
context of certain medical products, such as medical devices, the manufacturer
may discharge its duty to warn by providing an adequate warning to the treating
medical professional—the learned intermediary—rather than the patient. Felix v.
Hoffmann-LaRoche, Inc., 540 So. 2d 102, 104 (Fla. 1989); Buckner, 400 So. 2d at
822; see also Christopher v. Cutter Labs., 53 F.3d 1184, 1192 (11th Cir. 1995)
(applying Florida law). This duty to warn also applies to foreseeable off-label
uses of medical products. Upjohn Co. v. MacMurdo, 562 So. 2d 680, 683 (Fla.
1990). Warning the treating physician discharges the manufacturer’s duty to warn
because the physician “weighs the potential benefits against the dangers in
6 Case: 10-15327 Date Filed: 11/07/2012 Page: 7 of 21
deciding whether to recommend” the product to the patient. Felix, 540 So. 2d at
104.
The learned intermediary doctrine is a corollary to the rule that a medical
device manufacturer’s duty to warn runs to the treating physician. Christopher, 53
F.3d at 1192. This doctrine says that “the failure of the manufacturer to provide
the physician with an adequate warning of the risks associated with a [medical
device] is not the proximate cause of a patient’s injury if the prescribing physician
had independent knowledge of the risk that the adequate warning should have
communicated.” Id. Thus, even if the manufacturer breaches its duty to warn, it
may nevertheless mount an affirmative defense and avoid liability by
demonstrating the treating physician was otherwise aware of the particular risk
associated with the medical device. See id. at 1192-93; Walls v. Armour Pharm.
Co., 832 F. Supp. 1467, 1481–82 (M.D. Fla. 1993); Felix, 540 So. 2d at 105. We
have interpreted this defense to mean that “the causal link between a patient’s
injury and the alleged failure to warn is broken” if the treating physician “had
substantially the same knowledge” of the risks posed by the medical device “as an
adequate warning from the manufacturer should have communicated to [the
physician].” Christopher, 53 F.3d at 1192-93 (quotation marks omitted).
Here, in seeking summary judgment, Cook apparently did not dispute that it
7 Case: 10-15327 Date Filed: 11/07/2012 Page: 8 of 21
did not, at any point prior to the May 2007 procedure, warn Dr. Rush of the risk of
stroke associated with the use of its Formula 418 biliary stent in renal angioplasty
procedures.4 Instead, Cook mounted an affirmative defense under the learned
intermediary doctrine by arguing that Dr. Rush had independent and adequate
knowledge of the risk of stroke associated with the off-label uses of its biliary
stent. Thus, the question for us on summary judgment is whether, construing all
evidence in favor of Mr. Horrillo as the non-moving party, there is an issue of fact
about whether Dr. Rush had substantially the same knowledge as Cook of the risk
of stroke in using Cook’s Formula 418 biliary stent in renal angioplasty
procedures. See Christopher, 53 F.3d at 1193.
In asking us to reverse summary judgment, Mr. Horrillo argues that a
question of fact exists as to whether Dr. Rush was aware of the particular risk of
stroke in using the Formula 418 biliary stent in the renal artery. In response, Cook
does not challenge that it was aware its biliary stent posed a risk of stroke. Indeed,
the March 2007 meeting between the FDA and biliary stent manufacturers,
including Cook, identified the risk of stroke in using an expandable biliary stent in
4 While Cook offers a number of justifications for why it failed to warn Dr. Rush of the risks of using its stent in off-label procedures, these justifications are not relevant to the narrow question before us, which is whether Cook succeeds on its learned intermediary defense as a matter of law.
8 Case: 10-15327 Date Filed: 11/07/2012 Page: 9 of 21
renal arteries, and Cook acknowledged this risk in its October 2007 warning letter.
Rather, Cook argues that Dr. Rush was aware of that risk by pointing us to Dr.
Rush’s deposition in which he opined that the risk of stroke was “remote,” and
that “any type of risk like that was worth the possible benefit of the procedure.”
Cook also notes that Dr. Rush’s decision to use the Formula 418 biliary stent was
based on his own clinical judgment. According to Cook, this demonstrates, as a
matter of law, that Dr. Rush had substantially the same knowledge as Cook of the
risk of stroke associated with the off-label use of its Formula 418 biliary stent in
renal arteries. Cook also emphasizes that Dr. Rush has twenty-seven years of
experience in his field and has used hundreds of stents to treat renal stenosis.5
The evidence makes clear that Dr. Rush is experienced with the placement
of stents to treat renal stenosis. However, the facts are ambiguous as to whether
Dr. Rush had substantially the same knowledge as Cook of the particular risks
posed by the use of the Formula 418 biliary stent. Mindful that Cook bears the
burden of showing that Dr. Rush was aware of the risk associated with the
Formula 418 biliary stent, Cutter Laboratories, 53 F.3d at 1193, and that all facts,
5 Although Dr. Rush has less experience with the Formula 418 biliary stent, having used it “numerous times,” he is “pretty experienced” with the stent.
9 Case: 10-15327 Date Filed: 11/07/2012 Page: 10 of 21
inferences, and ambiguities are construed in favor of Mr. Horillo, see Layton, 686
F.3d at 1175, we conclude that there is a genuine issue of fact as to whether Dr.
Rush was aware of the risks posed by the Formula 418 biliary stent sufficient for
him to shield Cook under the learned intermediary rule.
First, we cannot conclude that Dr. Rush had substantially the same
knowledge as Cook because the evidence does not indisputably show that Dr.
Rush was aware of the likelihood or severity of potential complications posed by
the Formula 418 biliary stent that was known to Cook after its March 2007
meeting with FDA. Cook argues that Dr. Rush must have been aware of the risk
of stroke because of his education and training. While it is certainly possible that
through his research and experience Dr. Rush independently learned of the serious
risk of stroke described by the FDA, nothing in the record directly supports this
fact. To the contrary, Dr. Rush testified that he believed the possibility of a stroke
was a remote, unreasonable consideration. Although Dr. Rush is significantly
experienced in his field, Mr. Horillo’s expert witness, Dr. Marx, explained that
“practicing physicians don’t read every journal article that’s published” because
“it would be a full-time job.”6 As is proper at the summary judgment stage, we
6 Dr. Marx further explained that “it is the responsibility of [the] industry that makes these products to be aware of the significant findings and give that information to physicians.”
10 Case: 10-15327 Date Filed: 11/07/2012 Page: 11 of 21
decline to speculate about what Dr. Rush did or did not know based on his
education and experience. “[T]he drawing of legitimate inferences from the facts
are jury functions, not those of a judge.” Reeves v. Sanderson Plumbing Prods.
Inc., 530 U.S. 133, 149-50, 120 S. Ct. 2097, 2110 (2000) (quotation marks
omitted).
Second, Dr. Rush’s general experience does not necessarily prove that he
was aware of the specific risks posed by the Formula 418 biliary stent.
Specifically, the differences in safety between the Formula 418 biliary stent and
other stents are disputed.7 Certainly, Cook can argue to the jury that the risks
posed by the Formula 418 biliary stent were the same as other stents and therefore,
Dr. Rush would know of the risks posed by the Formula 418 biliary stent from his
considerable experience with other stents. However, a reasonable juror could
disagree with the assertion that the Formula 418 biliary stent was just as safe as
any other. For example, the stent’s own label provided that “[t]he safety and
effectiveness of this device for use in the vascular system have not been
established.” Further, Dr. Rush expressed interest in participating in trials to
7 The record in this case includes an abundance of testifying M.D.’s and Ph.D.’s. Each party listed ten experts on their respective witness lists, and by our count, at least seven doctors were deposed. We will not attempt to summarize the testimony of each of these witnesses, but rather note that the bounty of testifying doctors and/or experts merely underscores the fact- intensive nature of the dispute with which the jury will be presented here.
11 Case: 10-15327 Date Filed: 11/07/2012 Page: 12 of 21
prepare for Cook’s FDA filing for use of the Formula 418 biliary stent in the
vascular system. And finally in this regard, neither Dr. Rush’s general work with
stent placement, nor his specific experience with the Formula 418 biliary stent,
necessarily establishes that he was aware of the risks involved with the Formula
418 stent. A reasonable juror could find that the FDA issued a warning precisely
because the doctors frequently using the Formula 418 biliary stent, like Dr. Rush,
were unaware of the risks and serious complications of stroke and death. Because
Dr. Rush’s general experience with stent placement does not necessarily mean that
he had substantially the same knowledge as Cook, we conclude there are material
facts in dispute which must be decided by a jury.
Third, a reasonable juror might find that Dr. Rush’s knowledge that the stent
carried a remote risk of stroke was not substantially similar to the FDA’s serious
March 2007 warning of fatal and debilitating complications, including stroke. The
FDA listed a series of “serious” complications, including seizure and death. The
FDA also highlighted that a substantial percentage of the reported problems
associated with the use of the Formula 418 biliary stent occurred with off-label
use. Again, Dr. Rush described the risk of stroke as a remote, unreasonable
consideration and stated that despite the product’s warning regarding off-label use,
he felt “the effectiveness was probably very well established.” Because Dr. Rush
12 Case: 10-15327 Date Filed: 11/07/2012 Page: 13 of 21
was required to make sensitive judgments about the possible risks and benefits of
procedures and equipment, a reasonable juror might find that such a serious FDA
warning would have informed and influenced Dr. Rush’s knowledge base and
decision-making differently than his general belief that stents carry a remote risk
of stroke.
In sum, the evidence does not indisputably inform us that Dr. Rush had
substantially the same knowledge as Cook. Because a juror could reasonably
conclude that Dr. Rush’s education and experience with stent placement did not
equate Cook’s knowledge about the dangers of the off-label use of its stent, and
also that Dr. Rush’s belief of the remote risk of stroke contrasted with the serious
warnings given to Cook in the March 2007 meeting, the evidence allows for
differing interpretations. A jury should resolve this factual dispute. This is
especially true insofar as Cook bears the burden in asserting this affirmative
defense. Hunt v. Cromartie, 526 U.S. 541, 552, 119 S. Ct. 1545, 1552 (1999)
(“Summary judgment in favor of the party with the burden of persuasion . . . is
inappropriate when the evidence is susceptible of different interpretations or
inferences by the trier of fact.”).
IV.
13 Case: 10-15327 Date Filed: 11/07/2012 Page: 14 of 21
In light of the dissent’s position that summary judgment should also be
granted on the ground that there is no evidence that the use of the Formula 418
biliary stent caused Ms. Horillo’s injury, we briefly address the issue of causation
now as well. The complaint alleged generally that Cook was negligent in the
design, manufacture, and distribution of its stent, because, for example:
The COOK STENT did not come with adequate warnings and instructions regarding its appropriate use, or with warnings of its dangers when used as a renal stent, or with strict instructions as to the type of procedures for which it could be appropriately used, or with adequate instructions as to how it was to be utilized under different conditions, or with sufficient warnings and instructions to promote its safe usage;
The COOK STENT was a biliary stent and was negligently designed and promoted for use as a renal stent and was not approved by the FDA for “off-label” vascular use. Additionally, a similar biliary stent was recalled by the FDA on May 4, 2004. Thus defendant had knowledge of the COOK STENT’s negligent design as a renal stent;
After reviewing the complaint as a whole, we conclude that Mr. Horillo has
sufficiently alleged causation, in light of his alternative assertions of Cook’s
failure to warn; failure to instruct as to proper usage; and failure to act on its
knowledge of the earlier recall of a similar biliary stent.
The dissent specifically relies on the testimony of Dr. Marx, who explained
that it would be “medically improbable, if not impossible” for the stent to have
caused an air embolism in the brain, because the stent was not inflated with air and
14 Case: 10-15327 Date Filed: 11/07/2012 Page: 15 of 21
the renal artery does not flow directly to the brain. However, even accepting Dr.
Marx’s opinion as uncontested, that testimony would not prevent a reasonable
juror from finding that the Formula 418 biliary stent caused a stroke for a reason
other than an air embolism. Indeed, Dr. Marx testified that the stroke was
probably not caused by an air embolism, but by low blood pressure which resulted
from the placement of the stent. He explained that “the placement of the Formula
418 biliary stent in the renal artery . . . caused a destabilization of the
hemodynamics of the kidneys” because after the stent placement, the kidneys,
which regulate blood pressure, received a different amount of blood than they
were accustomed to getting. We are certainly aware that Dr. Marx’s theory that a
drop in blood pressure caused the stroke is contested by yet another expert–Dr.
Meyers. However, and again with regard to this issue as well, we conclude that
this type of dispute among experts about the cause of Ms. Horrillo’s stroke falls
precisely into the province of the jury.
V.
For these reasons, we REVERSE the magistrate judge’s grant of summary
judgment and REMAND for further proceedings consistent with this opinion.
15 Case: 10-15327 Date Filed: 11/07/2012 Page: 16 of 21
PRYOR, Circuit Judge, dissenting:
I would affirm the summary judgment in favor of Cook. The majority
concludes that the record is “ambiguous as to whether Dr. Rush had substantially
the same knowledge as Cook of the particular risks posed by the use of the
Formula 418 biliary stent.” ante at 9. The majority believes that a reasonable
juror could conclude that “Dr. Rush’s education and experience with stent
placement did not equate Cook’s knowledge about the dangers of the off-label use
of its stent.” Id. at 13
The problem with the majority opinion is that the record, construed in the
light most favorable to Horrillo, establishes that the “particular risk of stroke”
associated with the Formula 418 stent is no different from the ordinary risk
involved in any stenting procedure. Dr. Rush was aware of this risk independent
of any warning by Cook because he had conducted hundreds of renal angioplasties
with various kinds of stents and affirmed that he knew there was a risk of stroke
involved with the procedure. Dr. Rush has practiced as an interventional
radiologist for over 25 years and has conducted 20 years of protocol research for
the Food and Drug Administration, including research on vascular stents. Dr.
Rush had ample means to gain knowledge of the risk of stroke associated with
stenting procedures independent of any warning by Cook.
16 Case: 10-15327 Date Filed: 11/07/2012 Page: 17 of 21
A review of the testimony by Dr. Rush, particularly in the light of the
testimony of Horrillo’s expert witness, Dr. Marx, makes clear that Dr. Rush
possessed the same knowledge of the risk of stroke that any warning specific to
the Formula 418 stent would have provided him. The testimony of Dr. Marx
establishes that the “particular risks of stroke in using the Formula 418 biliary
stent in the renal artery” represents the risk involved in any stenting procedure.
An experienced interventional radiologist like Dr. Rush would have known about
this risk. Dr. Marx was explicitly asked whether there was anything unique about
the Formula 418 stent that could cause Horrillo’s stroke and answered that there
was not:
Q. Okay. Was there anything in particular about the Formula 418 Biliary Stent as opposed to any other biliary stent that produced her stroke? …. A. No. Q. Okay. So there’s nothing about our stent in particular, it was the procedure that was involved that is — you’re focusing on, am I correct in thinking that? A. Correct.
Dr. Marx testified that the risk of stroke came from blood pressure fluctuation
caused by increased blood flow to the kidney or embolism in the kidney caused by
emboli formed when the stent broke up the arteriosclerotic vascular disease. Dr.
Marx’s testimony establishes that this ordinary risk would be known by any
interventional radiologist performing a renal stent. As Dr. Marx testified, risks
17 Case: 10-15327 Date Filed: 11/07/2012 Page: 18 of 21
from fluctuations in blood pressure after renal stenting are “not something that
would not be known and understood by medical practitioners.” Although Dr.
Marx faulted Cook for not disclosing information about embolic risks to stenting,
he admitted that radiologists, “[i]n general[,] . . . accept minor embolic phenomena
everywhere in the body except in the brain in general.” He admitted that, even
after looking through all the medical charts, depositions, and medical articles that
Horrillo provided him, nothing persuaded him that the risk of embolization in the
kidneys was more than “minimal.”
Because Dr. Marx’s testimony establishes, without dispute, that the
“particular risk of stroke in using the Formula 418 biliary stent in the renal artery”
is the same risk involved in any stenting procedure, Horrillo is reduced to arguing
that there is an issue of fact as to whether Dr. Rush understood the general risks of
renal stenting, but there is no genuine issue of material fact that Dr. Rush
understood the general risks of renal stenting. Dr. Rush testified that he knew that
the ways the procedure could cause Horrillo “to have a stroke, potentially, might
be if I shut the renal artery down, occluded it completely, if she had a hypertensive
spike, that is, a spike in high blood pressure, and she would bleed into her brain.
That’s a possibility but a remote risk, and I felt that any type of risk like that was
worth the possible benefit of the procedure.” Dr. Rush undoubtedly knew that
there could be an increased flow of blood to the kidney because that was the entire
18 Case: 10-15327 Date Filed: 11/07/2012 Page: 19 of 21
reason for implanting the stent. Dr. Marx also testified that radiologists are aware
that any time they break up an atherosclerotic plaque, there is a risk of
embolization. Dr. Rush testified that the purpose of the angioplasty is to “push the
atherosclerotic disease, the hardening[,] out to open up the vessel.” As Dr. Marx
explained, embolization of some of this atherosclerotic disease is a common, well-
known phenomenon with minimal risks to a patient. After we construe all
ambiguities and factual inferences in favor of Horrillo, there is no genuine issue of
material fact as to whether Dr. Rush was aware of the “particular risk of stroke”
associated with the Formula 418 stent because that risk is no different from the
ordinary risk involved in any stenting procedure.
I would also affirm the summary judgment in favor of Cook because there is
no evidence of a causal connection between the use of the Formula 418 stent and
Horrillo’s injury under the theory Horrillo offers. When we review a summary
judgment, we can affirm “on any legal ground, regardless of the grounds addressed
and relied upon by the district court.” Cuddeback v. Fla. Bd. of Educ., 381 F.3d
1230, 1235 (11th Cir. 2004). Horrillo alleges that the Formula 418 stent likely
caused an air embolism because the stent used a balloon that could leak air into the
artery that could travel to the brain and cause a stroke. Horrillo’s complaint states
only one theory of causation: that the Formula 418 stent caused air to enter Ms.
Horrillo’s artery, which led to her stroke:
19 Case: 10-15327 Date Filed: 11/07/2012 Page: 20 of 21
The COOK STENT was negligently manufactured in that when it is implanted for vascular use, air may be introduced into the patient via the stent system causing serious complications, including seizure and stroke. …. [T]he stent was misused in that when the stent is implanted for vascular use, air may be introduced into the patient via the stent system causing serious complications, including seizure and stroke. …. The COOK STENT was negligently labeled regarding its correct or appropriate usage, in that when it is implanted for vascular use, air may be introduced into the patient via the stent system causing serious complications, including seizure and stroke.
There is no evidence to support this theory of causation because, as Dr. Marx
testified, it would be “medically improbable, if not impossible,” to get an air
embolism in the brain from a renal artery stent of this design. The majority quotes
part of paragraph 11 of Horrillo’s complaint, but that part says nothing—not one
word—about an alternative theory of causation.
An air embolism in this situation is “medically improbable, if not
impossible” for two reasons. First, the balloon on the Formula 418 stent is
inflated with a saline solution, not air. Second, the blood in the renal artery does
not flow directly to the brain but instead flows to the kidney and down into the
legs, making it “medically improbable, if not impossible, to get an embolus from a
renal artery stenting embolic event to go to the brain.” And Horrillo’s surviving
son never amended his complaint to reflect a different theory of causation. See
Bryant v. Jones, 575 F.3d 1281, 1308 (11th Cir. 2009) (“[A]bsent extraordinary
20 Case: 10-15327 Date Filed: 11/07/2012 Page: 21 of 21
circumstances, legal theories and arguments not raised squarely before the district
court cannot be broached for the first time on appeal.”).
We should affirm the summary judgment in favor of Cook. Although I
would affirm the summary judgment in favor of Cook based on the learned
intermediary doctrine, I would also alternatively affirm based on the absence of
evidence to support the theory of causation offered by Horrillo. I respectfully
dissent from the majority opinion that reverses the summary judgment in favor of
Cook.
