Visual inspection and flouroscopy were performed on the returned device.The reported kink/bend was confirmed; however, the reported difficult or delayed positioning could not be confirmed.The reported difficulty advancing the guide wire could not be replicated in a testing environment due to the condition of the returned device.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other similar incidents and/or complaints from this lot.The investigation determined the reported kink, difficulty advancing the device and difficult or delayed positioning appear to be related to operational context.It was reported by the account that the armada 14 catheter was successfully used one time in the procedure without any issues.The device was removed and reinserted for additional use.Based on the reported information and the analysis performed on the returned device, it appears that the bdc was inadvertently mishandled during removal after the first successful use of the device.Return analysis noted that the balloon inner member was stretched and folded proximal to the proximal end of the distal marker.The noted stretching likely occurred during removal of the device after first use which resulted in the inner member folding proximal to the proximal end of the distal marker and subsequently resulting in the reported kink, difficulty advancing the device and the markers being difficult to see.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.
