(b)(4).The device was returned for analysis with the outer member stretched at the proximal seal.The reported difficult to position was able to be confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other similar incidents from this lot.The investigation determined the reported/noted difficulties appear to be related to circumstances of the procedure as it is likely that interaction with the guide wire resulted in the noted stretched distal tip and the noted stretched outer member thus resulting in the reported difficulty to position.There is no indication of a product quality issue with respect to manufacture, design or labeling.The xience prox is currently not commercially available in the us; however, it is similar to a device sold in the us.

It was reported that the procedure was to treat a lesion located in the proximal to main left anteriior descending coronary artery.After advancing the xience prox 2.25 x 23 rx stent delivery system (sds) to the target lesion, the physician tried to move the stent some centimeters, when tip of the catheter met resistance with the non-abbott guide wire.After some additional attempts to advance the stent, the sds was then removed from the patient`s anatomy without any further issue.A new xience prox was used with the same guide wire to successfully complete the procedure.There were no reported adverse patient effect and no clinically significant delay in the procedure.No additional information was provided.Rg lab analysis on (b)(6) 2017 revealed the outer member was stretched at the proximal seal.
