It was reported that during preparation, the 3.50x48mm xience skypoint stent delivery system (sds) was attempted to be loaded through the wire; however, the stent struts were noted flared.Another device was used to complete the procedure.There was no patient involvement and no clinically significant delay in the procedure reported.Returned device analysis noted that the xience skypoint sds guide wire exit notch was noted to be torn with the lumen compromised.No additional information was provided.

The device was returned for analysis.The reported shaft tear was unable 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 similar incidents from this lot.The investigation was unable to determine a conclusive cause for the reported material deformation; however, factors that could contribute to material deformation include, but are not limited to, damage during manufacturing, inadvertent mishandling during sheath/stylet removal, preparation, during use of the device, interaction with accessory devices.In this case, it is possible that inadvertent mishandling during preparation of the device (sheath/stylet removal) may have contributed to the reported material deformation (stent damage); however, this cannot be confirmed.Additionally, the noted torn guide wire exit notch damage is consistent with interaction with a guide wire during use; however, a conclusive cause could not be determined based on the information provided.There is no indication of a product quality issue with respect to manufacture, design or labeling.
