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 other 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.The reported patient effect of dissection and treatments appear to be related operational context of the procedure.Additionally, 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.The reported patient effect of dissection is listed in the xience skypoint everolimus eluting coronary stent systems instructions for use as a known patient effect(s) of coronary stenting procedures.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported this was a procedure to treat a 100% stenosed and mildly tortuous de novo lesion in the proximal left anterior descending artery.A 2.75x23 xience skypoint stent delivery system (sds) was inserted advanced to the target lesion.However, during inflation, a contrast leak occurred due to a pinhole rupture.It was then observed that a dissection of the artery spread to the left main artery.The sds was able to be pressurized up to 16 atmospheres and the stent was successfully deployed.To treat the dissection, an additional xience stent was implanted.It was noted the vessel post procedure stenosis was 20%.There was no clinically significant delay in the procedure.No additional information was provided.

Additional testing was performed on 3 unused devices returned from the account.Visual inspection was performed with no damage noted to all 3 sterile devices.Therefore, a lot specific issue was not identified and no further actions are required.Based on the information reviewed, there is no indication of a product quality issue with respect to manufacture, design or labeling.
