It was reported that the procedure was to treat a de novo lesion located in the right coronary artery that was mildly calcified, moderately tortuous and 75% stenosed.After pre-dilatation, the xience skypoint stent delivery system was advanced to the lesion.During deployment, the balloon ruptured at 10 atmospheres.Additional balloon inflations were required to deploy the stent.Another planned xience skypoint was then implanted and both stents were post-dilatated with two non-abbott balloons.There was no adverse patient sequela or a clinically significant delay in the procedure.No additional information was provided.

A visual and functional inspection was performed on the returned device.The reported material rupture was 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.Factors that may contribute to material ruptures include, but are not limited to, material damage, materials, inflation technique, interactions with other devices, lesion calcification and tortuosity or insufficient preparation prior to use.There was no damage noted to the sds during the inspection prior to use or during preparation for use which suggests a product quality issue did not contribute to the reported difficulties.In this case, it is possible the device became damaged due to interaction with accessory devices during the procedure, thus causing the reported material rupture (balloon pinhole); however, this cannot be confirmed.The investigation was unable to determine a conclusive cause for the reported material rupture (balloon pinhole); however, the subsequent treatment appears to be related to circumstances of the procedure.There is no indication of a product quality issue with respect to the design, manufacture or labeling of the device.
