Fridley, Minnesota-based Medtronic said it received three complaints of suspected pump thrombosis in patients. Two of the patients died after their heart pumps were exchanged.
Medtronic found a malfunction when inspecting the three removed pumps, which were manufactured between December 2017 and May 2018, the company said in an Urgent Medical Device Correction notification signed by Mechanical Circulatory Support Quality and Regulatory Affairs VP Gail Schroeder.
