The U.S. FDA recently posted another round of recalls for the Cardiosave line of intra-aortic balloon pumps (IABPs) by Datascope Corp., advising users to make sure they have a backup unit at the ready in the case of device failure. However, the agency noted that “alternative treatments are limited,” a clear sign that this market lacks competition, most likely due to a lack of incentives for the private sector to invest in this class of devices.
