The product was returned with the membrane completely unfolded with blood on the exterior and interior of the catheter.A competitor sheath and stat-gard sleeve were also returned separate from the iab.The catheter tubing, optical fiber and inner lumen were cut at approximately 63.5cm form the iab tip.The remaining portion of the iab was not returned.The stat-gard sleeve was cut at approximately 31.5cm from the stat-gard sleeve tip.An inner lumen break within a kink was observed within the membrane at approximately 23.6cm from the iab tip.Additionally, a catheter tubing kink and an optical fiber break were also observed at approximately 30.5cm from the iab tip.The evaluation confirms the presence of a kink as an as analyzed failure.However, we are unable to conclusively determine when this kink may have occurred.Therefore, the root cause for the kink is impossible to define.A device and lot history record review was completed for the reported product.No nonconformance's were found that are considered to be related to the event.
