Qn#(b)(4).The customer returned one epidural catheter piece.A visual exam was performed and it was observed that most of the catheter was returned as the proximal tip was undamaged and intact.At the other end, the catheter appears to have been cut.The coils remained tightly wound and did not extend beyond the extrusion.The catheter's inner coils were offset at approximately 18cm from the proximal end.Microscopic examination also revealed a small cut in the catheter extrusion and flattened coils.No other defects were observed.The returned catheter piece was measured and was found to be out of specification.Approximately 56.7cm of the catheter was missing.Functional testing was performed and a leak was found in the catheter.A dhr review was performed on the epidural catheter with no relevant findings.The reported complaint of a hole in the epidural catheter was confirmed based upon the sample received.The customer only returned approximately 31.8cm of the catheter.Functional and visual inspection of the returned epidural catheter piece confirmed to have two small cuts in the extrusion approximately 18cm from the proximal end.Other remarks: a dhr review was performed on the epidural catheter with no evidence to suggest a manufacturing related cause.Therefore, based upon the observed damage and the time of discovery, it was determined that operational context caused or contributed to this event.
