The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint that the cuff was exposed was inconclusive due to the nature of the complaint and the condition of the complaint sample.One pourchez retro catheter was returned for investigation.Evidence of use was observed on the catheter.Residue was observed on the connectors and extension legs.The catheter was received in two segments.The proximal catheter segment extended 4.6cm from the distal end of the cuff.The overall length of the distal catheter segment was 22.7cm.The adjoining ends of the catheter revealed a glossy and striated cross section, which is indicative of a cut made with a sharp instrument.Breaches were observed in the proximal end of the distal catheter segment.The adjoining surfaces of the breaches in the tubing also exhibited glossy and striated surfaces with sharp edges.The catheter was most likely cut after it was removed.The cuff was in the proper position and secured just distal to the tapered hub.Blood residue was observed within the fibers of the cuff.Minimal, if any, tissue ingrowth was observed within the exposed fibers.What caused the cuff to dislodge is unknown.Potential contributing factors of the catheter dislodgement include pulling on the catheter, patient factors associated with cuff in-growth, and securement technique.The ifu warns, ¿do not over-expand subcutaneous tissue during tunneling.Over expansion may delay/prevent cuff in-growth, and can increase bleeding.¿ no further action is required because the reported event could not be related to a deficiency in product manufacture or deficiency while under correct product use.
