Event Description
|
It was reported that the procedure was to treat the heavily calcified, mildly tortuous left superficial femoral artery (sfa).The vessel diameter was 5.5 mm and lesion length was 130 mm.Atherectomy was not performed.The lesion was prepared with a 6x150 mm non-abbott balloon at 20 atmospheres for 120 seconds.Using a crossover approach technique from the right common femoral artery (cfa) site, the 5x150 mm supera self expanding stent system (sess) was attempted to be deployed; however, the thumb slide was too tight and the stent only partially deployed.The supera sess was removed from the anatomy and a new same size supera sess was used to complete the procedure.In the physician's opinion the issue was possibly due to resistance in the heavily tortuous cfa bifurcation.There were no adverse patient effects and there was no clinically significant delay in the procedure.No additional information was provided.

Manufacturer Narrative
|
The device was returned for analysis.The reported activation failure and mechanical jam were unable to be 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 other similar incidents from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that interaction with the heavily tortuous right common femoral artery bifurcation resulted in the ratchet being unable to properly engage and release the stent from the delivery system thus resulting in reported activation failure/ deployment failure and the reported mechanical jam.There is no indication of a product quality issue with respect to manufacture, design or labeling.
