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 damaged guidewire was confirmed and the cause appeared to be use-related.The product returned for evaluation was one 18ga x 10cm powerglide pro midline catheter assembly.Usage residues were observed throughout the sample.A break was observed in the core wire and the coil wire was elongated.A permanent bend was observed in the core wire distal of the break site.The weld tip was intact.Microscopic inspection of the needle revealed mechanical damage along the proximal edge of the bevel.Inspection of the wire break revealed a granular fracture surface.A tapered region of increased luster was observed.The needle bevel damage and the core wire break features were consistent with the wire being sheared against the needle bevel.Such damage can occur if the wire is retracted at a sharp angle against the needle bevel.
