It was reported that the procedure was to treat a lesion in the left circumflex (lcx) artery, with heavy tortuosity and mild calcification.Pre-dilatation was performed with a 2.5 x 12mm non-compliant (nc) balloon at 16 and 18 atmospheres, reducing the stenosis to less than 40%.The 3.0 x 28 mm device was advanced, but could not cross due to the anatomy.A xience xpedition was used to successfully complete the procedure.There was no reported clinically significant delay due to the failure to cross.There was no adverse patient effect.No additional information was provided.Returned device analysis on (b)(4) 2014 observed material peeling on the balloon.

(b)(4).Though the device is not approved for sale in the u.S., it uses a delivery system which is similar to a device sold in the u.S.Evaluation summary: the device was returned for evaluation.The failure to advance could not be replicated in a testing environment as it was based on operational circumstances.Balloon shredding/peeling was observed, which was likely caused by the interaction with the tortuosity and calcification.Based on visual and dimensional analysis of the returned device, there is no indication of a product deficiency.A review of the lot history record revealed no non-conformances that would have contributed to this complaint.A query/review of the complaint history of the reported lot did not indicate a manufacturing issue.Based on the information reviewed, there is no indication of a product deficiency.
