(b)(4).Correction: the device was initially reported as returning for analysis, but has now been reported as not returning because it was discarded at the account.The incident information was reviewed; however, the product was not returned for analysis.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 reported from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure.In this case, based on the reported information, it is likely that as the guide wire was advanced toward the lesion, interaction/resistance was met with the heavy calcification in the anatomy resulting in the reported resistance causing the polymer to bunch.Manipulation and/or inadvertent mishandling during retraction against the anatomy or other devices used resulted in the polymer peeling.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
