Cardiovascular Systems is recalling certain lots of the Diamondback 360 Peripheral Orbital Atherectomy System, because they may contain defective saline sheaths that could fracture during use. If this happens, fragments of the sheath could possibly block blood vessels. The U.S. Food and Drug Administration (FDA) said as of this week, there are no reports of patient injuries to date.
The model number for the system in DPB-125MICRO145 (Part number 7-10003). The affected lot numbers include: 100573, 100575, 100674, 100676, 100678 and 100680. The vendor said 94 affected devices were manufactured from May 8, 2014 to May 9, 2014, and 48 were distributed from May 16, 2014 to May 20, 2014.
The Diamondback 360 Peripheral Orbital Atherectomy System is a high-speed cutting tool inserted via a catheter through the skin into a patient’s blood vessel. The system is used to reestablish blood flow in narrowed arteries or arterio-venous dialysis shunts.
