The device was returned for analysis.The reported stretched stent and the reported stent material separation were unable to be replicated in a testing environment due to the condition of the returned device (stent not returned).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.As there was no damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that after stent deployment during delivery system removal the stent inadvertently got caught on the delivery system and/or the introducer sheath; thus resulting in the reported stretched stent and the reported stent material separation.Manipulation of the compromised device resulted in the noted device damages (multiple sheath wrinkles, jacket smashed/separated, inner member separated).There is no indication of a product quality issue with respect to manufacture, design or labeling.Na.
