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 activation failure appears to be related to operational context of the procedure as it is likely the reported material rupture contributed to/caused the reported activation failure.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 mildly calcified right coronary artery (rca).A 2.25x15mm xience sierra stent delivery system (sds) was advanced to the target lesion without issue; however, the balloon failed to inflate with the indeflator.Inflation was attempted three times and would not hold pressure.The sds was removed and on the table, an attempt was made to inflate the balloon and a balloon leak was observed.Another same size xience sierra and the same indeflator was used to successfully complete the procedure.There was no adverse patient effects and no clinically significant delay.No additional information was provided.
