The product was returned with the membrane completely unfolded with blood on the exterior of the catheter and between the catheter and the returned non-maquet sheath.The pressure tubing was also returned.The extracorporeal tubing was returned cut at 34.3cm from the rear of the y-fitting.A catheter tubing/inner lumen/sheath kink was observed at approximately 50cm from the iab tip.At this same location, the optical fiber was found to be broken.An additional catheter tubing kink was also observed at approximately 76.2cm from the iab tip.Lastly, an inner lumen break from a severe kink was observed at approximately 24.4cm from the iab tip.An underwater leak test of the balloon, catheter, y-fitting and extracorporeal tubing was performed and a leak was observed at the inner lumen break site.A 0.025" guidewire was inserted into the inner lumen where a blood occlusion was felt.Unable to clear occlusion.The reported problem appears to have been caused by a kink on the inner lumen which developed into a break and causing a leak.However, we are unable to conclusively determine when this kink may have occurred.The evaluation confirmed the problem.A lot history record review was completed for the reported product.No nonconformances were found that are considered to be related to the event.(b)(4).
