(b)(4).The product was returned with the membrane completely unfolded and blood on the interior and exterior of the catheter and the membrane.The extender tubing, the one way valve, the pressure tubing and the sheath were also returned.One kink was found on the catheter tubing approximately 76.7cm from the iab tip.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal and extender tubing was performed and 1 leak was detected at the membrane rear seal.The evaluation confirmed the reported problem.The reported problem was most likely triggered by a leak which was found at the rear seal of the membrane.The leak likely occurred during therapy since iab catheters are leak tested 100% in manufacturing.A device and lot history record review was completed for the reported product.No non-conformances were found that are considered to be related to the event.Complaint # (b)(4); record # (b)(4).
