It was reported that the procedure was to treat a moderately calcified left anterior descending artery that is 80% stenosed.The 3.5x48mm xience xpedition stent delivery system was advancing through an unspecified guide catheter; however, could not advance further as resistance was noted with the unspecified guide catheter.Once withdrawn it was noted the struts were flared.Another xience xpedition was used to successfully complete the procedure.There were no adverse patient effects reported and no clinically significant delay reported.Per device analysis the outer member was torn 1.6cm distal from the guide wire lumen for a length of 3mm.The balloon did not inflate, and fluid was observed coming out from the tear in noted the outer member.No additional information was provided.

A visual, dimensional, and functional inspection were performed on the returned device.The reported material deformation was confirmed.The reported difficult to advance could not be tested as it was based on operational context.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 of the reported lot did not indicate a lot specific quality issue.The investigation was unable to determine a conclusive cause for the reported difficulties, the noted leak / splash, and the noted torn material.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
