Device evaluation: as received, the specimen consists of one hydro gw std an 260-035; returned coiled, loose and double-bagged within large zip-lock style poly pouches.A review of the device history records of the specimen device does not present any indication of manufacturing defect or anomaly that could have impacted on the event as reported.The history records indicate this product was final inspection tested at lake region medical and was determined to be acceptable.The specimen presents a kink located 8.30cm from the distal tip and skive damage to the polymer jacket material 145.3 to 169.5cm from the distal tip and bunched polymer jacket material located 169.5 to 170.3cm from the distal tip.The specimen has sustained a fracture through the wire and polymer jacket material 193.2cm from the distal tip.The material proximal of the fracture is not included with the returned wire.The core wire fracture presents indications of a low cycle bending fatigue overload fracture; the polymer jacket presents indications of a ductile tensile overload fracture.At this time it is not possible to assign a definitive root cause for the event as reported.The damage presented by the specimen appears consistent with manipulating the wire against resistance.As noted in the warnings section of the device instructions for use (dfu), "if any resistance is felt or if the tip's behavior and/or location seems improper, stop manipulating the zipwire hydrophilic guide wire and or the catheter and determine the cause by fluoroscopy.Failure to exercise proper caution may result in bending, kinking, separation of the guide wire's tip, damage to the catheter, or damage to the vessel." based on the information provided, procedural and/or clinical factors appear to have impacted on the event as reported.If there is any further relevant information provided, a follow up medwatch report will be submitted.
