Event Description
|
It was reported that the procedure was to treat a heavily calcified, mildly tortuous popliteal artery.The 5.0x40mm supera self-expanding stent system was attempted to be deployed; however, part of the stent was released and was not able to release the stent further.The stent became compressed (not fully expanded) and the shaft of the device was pulled to attempt to release the compressed stent, but failed.The thumbsilde was pushed further and finally was able to release the stent; however, part of the implanted stent remained compressed.The stent delivery system was removed under fluoroscopy.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.

Manufacturer Narrative
|
The device was returned for analysis.The reported difficult/delayed activation and the reported defective device-shortened stent were unable to be confirmed as the stent was not returned.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.It is possible that during deployment interactions with the heavily calcified, mildly tortuous anatomy and/or other devices resulted in the ratchet being unable to fully release the stent from the delivery system resulting in the reported difficult or delayed activation; however this cannot be confirmed.Additionally, interactions with the heavily calcified mildly tortuous anatomy possibly resulted in the reported defective device (stent became compressed/not fully expanded); however this cannot be confirmed.The investigation determined a conclusive cause for the reported difficulties cannot be determined.There is no indication of a product quality issue with respect to manufacture, design or labeling.
