Ref:(b)(4).Ref: mw5067576 received 15-feb-2017.The product was returned with the membrane completely unfolded and blood on the interior of the exterior of the catheter.The extension tubing was also returned.An underwater leak test of the balloon, catheter, y-fitting, extracorporeal and extension tubing was performed and one leak was detected on the membrane at the rear seal 1.3 cm measuring 0.013 m in length.The reported problem was most likely triggered by a leak which was found on the membrane.The penetration found on the membrane appears to have been caused by a sharp object.The evaluation confirmed the reported problem.We are unable to determine when this may have occurred.
