I. INTRODUCTION This matter is before the Court on Defendant Thoratec LLC’s Motion to Dismiss [Docket No. 17] and Defendant’s unopposed Request for Judicial Notice [Docket No. 20]. The Court heard oral argument on March 24, 2021. For the reasons that follow, Defendant’s motion to dismiss is denied. II. BACKGROUND A. Factual Background 1. The HeartMate 3 Defendant Thoratec LLC (“Thoratec”) is a limited liability company with

its principal place of business in California. (Compl. ¶ 6.) Thoratec is a subsidiary of Abbott Laboratories, Inc. (“Abbott”). (Id.) Thoratec develops,

manufactures, and markets proprietary medical devices used for mechanical circulatory support, including the Heartmate 3TM Left Ventricular Assist System (“HeartMate 3”), an implantable medical device approved by the FDA to treat

patients suffering from end-stage heart failure in the form of advanced refractory left ventricular heart failure. (Compl. ¶ 6; Lewis Decl., Ex. 3, Summary of Safety

and Effectiveness Data (“SSED”) at 1.) The HeartMate 3 reroutes and pumps blood from the left ventricle into the ascending aorta. (Compl. ¶ 11.) An apical cuff is sewn into the epicardium

around a cored opening near the apex of the left ventricle which serves as a securing interface between the HeartMate 3 and the patient’s heart. (Compl. ¶¶

13-14.) The inflow cannula of the pump is then inserted into the apical cuff on the left ventricle and fixed securely into place by a locking mechanism unique to the HeartMate 3 (the “slide-lock mechanism”). (Compl. ¶¶ 15-16.) The slide-

lock mechanism affixes the pump to the apical cuff using two symmetrical locking arms which surround the inflow cannula and secure it to the heart by engaging a metal ring on the apical cuff, creating an airtight seal between the

inflow cannula and apical cuff. (Id. ¶ 16.) 2. Implantation of the HeartMate 3 into Arvid Herrman

On June 25, 2019, cardiovascular surgeon John Stulak, M.D., implanted a HeartMate 3 into Arvid Herrman at the Mayo Clinic in Rochester, Minnesota. (Compl. ¶¶ 35, 37.) Herrman was a resident of Wisconsin. (Id. ¶ 4.) Minutes

after turning on the HeartMate 3, Hermann’s left ventricle and ascending aorta filled with air, and Hermann was placed back on a cardiopulmonary bypass.

(Compl. ¶¶ 41-42.) Stulak shut off the HeartMate 3, de-aired the ascending aorta and left ventricle, and then turned on the HeartMate 3 again, weaned Herrman from bypass, and increased the pump speed. (Compl. ¶ 43.) Again, a large bolus

of air appeared in the ascending aorta, and Herrman was placed back on bypass. (Id.) The process of de-airing and then restarting the pump was repeated and, a

third time, a large amount of air appeared in the left ventricle and ascending aorta, and Herrman was placed back on bypass. (Id. ¶ 44.) While Herrman was still on bypass and the HeartMate 3 pump was running, Stulak observed air

entering Herrman’s left ventricle from around the inflow cannula. (Id. ¶ 45.) Stulak noted that the HeartMate 3 could rotate freely on the apical cuff even

though it was locked into place by the slide-lock mechanism. (Id. ¶ 46.) Stulak removed the HeartMate 3 and compared it to the underside of a newly opened replacement HeartMate 3. (Compl. ¶ 47.) He observed that the

locking arms of the explanted HeartMate 3 were asymmetrical and that the left locking arm of the explanted HeartMate 3 was bent and distracted away from the

inflow cannula. (Id.) Stulak concluded that the bent left locking arm of the slide- lock mechanism rendered the explanted HeartMate 3 device defective and created negative pressure allowing air to leach into the ventricle. (Id. ¶¶ 48-49.)

Stulak implanted a replacement HeartMate 3 with locking arms that were symmetrical and not bent. (Compl. ¶ 50.) He engaged the slide-lock mechanism

without difficulty, the pump functioned normally, and the surgery was concluded. (Id.) However, Herrman never regained consciousness and, on July 12, 2019, Hermann passed away. (Compl. ¶¶ 51-53.) His cause of death was

determined to be multiple air emboli caused by a leak at the interface between the inflow cannula and apical connector of the explanted HeartMate 3, resulting

in severe brain injury and multi-organ failure. (Id. ¶ 53.) The explanted HeartMate 3 was returned to Thoratec for inspection, and

Thoratec confirmed that the locking arms were asymmetrical and one of the arms was bent outward, deviating from the FDA-approved specifications. (Compl. ¶ 54.)

3. Medical Device Amendments The 1976 Medical Device Amendments (“MDA”) to the Food, Drug, and

Cosmetic Act (“FDCA”), 21 U.S.C. § 360C et seq., created a comprehensive “regime of detailed federal oversight” for medical devices. Riegel v. Medtronic,

552 U.S. 312, 316 (2008). The MDA creates three classes of medical devices based on use and level of potential risk. Buckman Co. v. Plaintiffs’ Legal Comm., 531 U.S. 341, 343 (2001). The HeartMate 3 is a Class III medical device, i.e., one that

“support[s] or sustain[s] human life” or “presents a potential unreasonable risk of illness or injury” and, thus, “incur[s] the FDA’s strictest regulation.” Id.; 21

U.S.C. § 360c(a)(1)(C)(ii). Before a new Class III device may be marketed, the manufacturer must assure the FDA through a rigorous Pre–Market Approval (“PMA”) process that the device is safe and effective. Once the product is approved, the manufacturer may not change its design, manufacturing process, labeling, or other attributes that would affect safety or effectiveness without filing a PMA Supplement. The PMA Supplement is reviewed using the same standard as the original PMA. In re Medtronic, Inc., Sprint Fidelis Leads Prod. Liab. Litig., 623 F.3d 1200, 1203 (8th Cir. 2010) (citations omitted) (“Sprint Fidelis II”).

4. FDA Approval of the Heartmate 3 On August 23, 2017, the FDA granted premarket approval for the

HeartMate 3 for short-term hemodynamic support, as a “bridge to [heart] transplant or bridge to myocardial recovery.” (Compl. ¶ 30.) On October 18,

2018, the FDA approved the HeartMate 3 for long-term mechanical circulatory support, or as a “destination therapy.” (Id. ¶ 31.) One of the design specifications set forth in the FDA-approved PMA for the HeartMate 3 requires

the two locking arms of the slide-lock mechanism to be symmetrical and coapt uniformly around the inflow cannula of the pump, so that the inflow cannula

tightly affixes to the apical cuff on the left ventricle and air does not leak at the cannula-cuff interface. (Id. ¶¶ 27-28, 32.) B. Procedural History

On September 4, 2019, a Minnesota state court appointed Plaintiff Jamie Edwards, a resident of Wisconsin, as trustee for the heirs and next of kin of Herrman. (Compl. ¶ 5.) On December 3, 2020, Plaintiff filed a Complaint against Abbott and

Thoratec in this Court. [Docket No.
