It was reported that the procedure was to treat a 90% stenosed, mildly calcified and moderately tortuous lesion in the proximal left circumflex artery (plcx).The 2.5x18mm xience skypoint stent delivery system (sds) balloon was inflated, however, the balloon ruptured during the first inflation at 8 atmospheres.The sds was mostly contained within the guiding catheter; therefore, was removed with the guiding catheter.Another xience skypoint was used to continue the procedure.There were no adverse patient effects and there was no reported clinically significant delay in the procedure.

A visual and functional inspection was performed on the returned device.The reported material rupture was not confirmed; however, a material separation [of the shaft] was observed.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 did not indicate a lot specific quality issue.A conclusive cause for the reported material rupture and observed material separation could not be determined; however, factors that may contribute to material ruptures include, but are not limited to, material damage, inflation technique, interaction with accessory devices, lesion calcification and tortuosity or insufficient preparation prior to use.Potential causes for a material separation include, but are not limited to, damage during manufacturing, inadvertent mishandling during unpackaging, during preparation or use of the device, interaction with the anatomy and/or accessory devices.There was no damage noted to the stent delivery system (sds) during the inspection prior to use which suggests a product quality issue did not contribute to the reported material rupture.
