Device evaluated by manufacturer: returned product consisted of the rotapro atherectomy system.The burr catheter was connected to the advancer unit.The advancer, handshake connections, sheath, coil, burr and annulus were visually and microscopically examined.Inspection of the device revealed that the coil was kinked and stretched at the handshake connection.The rotawire used in the procedure was returned and used for analysis.The wire was inserted into the annulus and advanced up to the damaged coil; however, the wire wouldn't pass the damaged coil.When the coil is kinked and stretched, the damage will not allow the guidewire to be advanced.Product analysis confirmed the reported events, as the coil was kinked and stretched, restricting the guidewire from advancing through the device.
