The device 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 similar incidents from this lot.The investigation determined the reported difficulties and treatment appear to be related to circumstances of the procedure as it is likely the device interacted with the previously placed stent causing the reported failure to advance.During removal continued resistance was felt causing the reported entrapment and subsequent stent dislodgement.A series of balloons were used to place the dislodged stent causing a delay in the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was to treat the first diagonal branch artery.The 2.25x15mm xience skypoint stent delivery system (sds) was trying to cross a previously deployed stent in the left anterior descending (lad) but could not go through.Upon removal, the xience skypoint stent got snagged with the previously deployed stent.Since the lad was bypassed, a series of balloons were used to inflate the stent in the lad.The patient is okay, however, there was a delay in the procedure.No additional information was provided.
