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 was unable to determine a conclusive cause for the reported material rupture; however, factors that may contribute to material ruptures include, but are not limited to, material damage, interactions with other devices or interaction with lesion calcification and tortuosity.Additionally, the reported rupture likely caused the reported failure to deploy (activation failure).It should be noted there was no damage or leak noted to the stent delivery system (sds) during the inspection prior to use or during preparation of the device, which suggests a product quality issue did not contribute to the reported difficulties.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 a 90% stenosed de novo lesion in the distal right coronary artery with moderate calcification and moderate tortuosity.After pre-dilatation, the 2.75x28mm xience skypoint stent delivery system (sds) was advanced to the target lesion and the stent was attempted to be implanted; however, the balloon of the sds ruptured at 8 atmospheres during the first inflation and the stent did not deploy.The sds was removed from the patient, and additional pre-dilatation was performed.A 2.5x28mm xience skypoint stent was successfully deployed and post-dilated to complete the procedure.There was no adverse patient effect and no clinically significant delay reported in the procedure.No additional information was provided.
