The following were reviewed as part of this investigation: patient severity, applicable previous investigation(s), sample analysis, applicable fmea documents, applicable manufacturing records, and labeling.Based on a review of this information, the following was concluded: the complaint of a leak in the catheter was confirmed, but the cause was unknown.One 5fr triple lumen (t/l) powerpicc solo was returned for investigation.The catheter exhibited evidence of use.The t/l tubing extended 1.5mm distal to the 5cm depth mark.A non-vad injection cap was attached to the gray solo connector.The extension leg with the gray connector was slightly cloudy.Use residue was observed on the sample.A functional test revealed fluid leaking from the t/l tubing just distal to the molded trifurcation when the gray lumen was pressurized.A microscopic examination of the leak site revealed a 1mm breach in the circumferential direction.The adjoining surfaces of the breached tubing were striated, which is consistent with damage caused by a sharp instrument.Striations were observed in a 2mm x 1mm area at the distal end of the molded trifurcation adjacent to the leak site, which indicates that material had been removed from the trifurcation with a sharp instrument.It appears that the breach in the tubing was caused when material was removed from the distal end of the trifurcation.Material had also been removed from another area at the distal end of the trifurcation 180-degrees from the leak site.It was reported that no problems were reported during insertion and verification of the picc at the time of placement.The instructions for use (ifu) indicates to flush the catheter prior to use.The ifu also indicates to aspirate and flush after placement to ensure patency.Due to the evidence of use observed on the returned sample and since no leaks were observed before and immediately after insertion, it appears that the catheter may have been damaged during use; however, the exact cause was unknown.
