It was reported that the procedure was to treat a lesion in the mid left anterior descending (mlad) coronary artery with heavy calcification, mild tortuosity and 75% stenosis.During negative pressure test outside the anatomy, the 4.0x12mm xience skypoint stent delivery stent (sds) was observed to have a pinhole leak around the balloon center.The device was not used and there was no patient involvement.A non-abbott 4.00×12 stent was used to complete the procedure.There was no clinically significant delay in the procedure.No additional information was provided.

The device was not returned for evaluation.The electronic lot history record (elhr) and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a review of the complaint history identified no other incidents.A conclusive cause for the reported leak/splash could not be determined.Factors that may contribute to a leak include, but are not limited to, inflation technique, contrast concentration, loose connection with the indeflator, contamination in the inflation lumen or damage to the balloon, guide wire and/or inflation lumen.In this case, it is possible that inadvertent mishandling during sheath removal may have pinched the stent onto the balloon material causing the reported leak/splash; however, based on the information provided and without the device to examine, this cannot be confirmed.There is no indication of a product quality issue with respect to manufacture, design, or labeling; therefore, no product-related corrective action will be implemented in this case.
