On December 23, 2016, the US Court of Appeals for the First Circuit issued an opinion in United States ex rel. D’Agostino v. ev3, Inc. (Case No. 16-1126), affirming the US District Court for the District of Massachusetts’s denial of a relator’s motion for leave to file a fourth amended complaint under the False Claims Act (FCA).
The relator, a former sales representative at ev3, a medical device developer and manufacturer, alleged that his former employer and its subsidiary, Micro Therapeutics, Inc., violated provisions of the FCA by selling two products, the Onyx Liquid Embolic System (Onyx) and the Axium Detachable Coil System (Axium), to hospitals seeking reimbursements by the government through the Centers for Medicare & Medicaid Services (CMS).
