The 13.5f silicone hemo-cath was returned for evaluation.As it was reported air was noted in the arterial extension, the distal tip of the lumen was clamped and the arterial side was flushed.No leaks were noted.The venous side was then flushed revealing a leak in the lumen approximately 0.1 cm from the hub.Under magnification the leak appears to originate from an external puncture.The contract manufacturer conducted a review of the manufacture process for the lot number reported.Their investigation revealed nothing out of specification, no amv (authorized manufacturer variance), ncr (non-conformance report) or reworks related to the reported failure mode were found.Lot was manufactured according to specifications.The manufacture process includes a 100% leak test performed as a last step in the process.This test would have detected any leaks, holes, or weak spots if it had existed at the time of manufacture.A definitive root cause cannot be determined but is not likely manufacture related.The instructions for use (ifu) contains the following warnings and precautions: *do not use sharp instruments near the extension lines or tubing.*examine catheter lumens and extensions before and after each treatment for damage.
