Endologix Inc. has resumed shipping of some of its AFX endovascular abdominal aortic aneurysm systems, after placing the devices on hold. This brought an end to a rather tumultuous week for the Irvine, Calif.-based company's stock (NASDAQ: ELGX), which plummeted as much as 27 percent upon news of the hold. However, shares of the stock slightly rebounded late last week. (See Medical Device Daily, Dec. 28, 2016.)
