In April 2019, Food and Drug Administration (FDA),a federal agency of US department of health and human services, a regulatory body, has sent a product recall notice to THORATEC Corporation, for its product HEARTMATE II, a left ventricular assist system, EU, due to adverse risks, blood pumping issues, use problems, power and battery problems identified. FDA has sent a notice for product recall as the product defect contributed to aortic insufficiency and potential pump obstruction in the patient which led to emergency heart transplant. Similarly, in the cardiac assist devices market in 2018, FDA came across 24,036 device problems out of which 10,788 were use problems, 1,791 blood pumping problems, 1,450 power problems, 1,402 battery problems, 949 connection problems, and others. Risks associated with implantation of cardiac assist devices into the human body acts as a major restraint for the growth of this market.
