The following were reviewed as part of this investigation: patient severity, trend analysis, applicable previous investigation(s), sample (if available), and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a leaking catheter was confirmed and the cause appeared to be use related.The product returned for evaluation was one 4fr s/l powermidline midline catheter.Usage residues were observed throughout the sample.A small split was observed approximately midway along the length of the extension tube.Microscopic inspection of the split revealed sharply defined fracture features.The fracture surface exhibited a granular fracture surface.Material abrasion was observed in the vicinity of the split, as well as circumferentially opposite the split site.An attempt to infuse water through the sample using a 12ml syringe revealed the sample to be patent to infusion; however, a leak was observed emanating from the site of the aforementioned split.The fracture features and material abrasions were consistent with damage caused by contact between the catheter and a traumatic grasping instrument such as forceps or hemostats.The product ifu states ¿caution: do not allow accidental device contact with sharp instruments.Mechanical damage may occur.Use only smooth edged, atraumatic clamps or forceps.¿ the location of the damage suggested that catheter maintenance may have contributed.A lot history review (lhr) review is not possible, as no manufacturing lot number has been provided by the complainant.
