Twin-pass device was returned for evaluation.The manufacturing records were reviewed and no nonconformances related to this lot were found, therefore supporting the device met material, assembly and performance specifications prior to shipment.The complaint was confirmed, the distal tip of the device was separated.The proximal side of the otw port to the separation point measured 5mm suggesting that 2-2.5 cm of tip was missing.The pebax material at the separation point was stretched signifying the catheter was pulled against resistance.The distal most section shows that all three construct layers were present.The rx lumen of the catheter was split longitudinally from distal to proximal.
