One deltec power port was returned for analysis in used condition.Upon visual examination the catheter was noted to not be completely inserted.The catheter was removed from the port.The port was tested with a new catheter; components were found to be correct.Relevant documents were reviewed and deemed adequate.Ports line clearance record, training records, and tube coating operation were all reviewed; no discrepancies were found.The tube coating operation was further reviewed by auditing 32 units; no discrepancies were observed.Based on the evidence, the complaint was confirmed.The most probable root cause was manufacturing as the tube was not properly covered with silicone.
