The device was not returned for analysis.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history did not indicate a lot specific quality issue.The investigation determined the reported difficulties appear to be related to the operational context of the procedure.In this case, it is likely the device interacted with the heavily calcified, heavily tortuous, 90% stenosed lesion during advancement, as resistance was noted, resulting in the reported failure to advance.Further interaction with the challenging anatomy during retraction of the device, as resistance was noted, likely contributed to the reported difficult to remove.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was performed to treat a lesion in the heavily calcified, heavily tortuous, 90% stenosed right coronary artery.A 4x12mm xience skypoint stent delivery system (sds) failed to cross due to the anatomy and faced resistance during removal with the anatomy.An unspecified balloon was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
