Event Description
|
It was reported that the procedure was to treat a left superficial femoral artery.Lesion was pre-dilated with a 5mm balloon.An absolute pro stent was advanced and deployment initiated.Some of the stent was already partially deployed when the ratchet became stuck on the deployment lever, so it was decided to remove the device completely.But when the catheter was pulled back, the stent further deployed a bit more (still partially remaining in the sheath).It was also noted that the stent implant had fractured (not in two pieces).The device was simply withdrawn.A 6x100 absolute pro was used to successfully complete the procedure.There were no adverse patient effects and no clinically significant delay in the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.

Manufacturer Narrative
|
A visual and functional analysis was performed on the returned device.The reported deployment issue, resistance with the thumbwheel and broken stent were not confirmed as the stent was already fully deployed and 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 indication of a lot specific product quality issue.The investigation was unable to determine a definitive cause for the difficulties.It may be possible that the distal shaft was bent or restricted in the anatomy (possibly at the aortic bifurcation) preventing the shaft lumens from moving freely and causing resistance with the thumbwheel; however, this could not be confirmed.The chatter marks noted throughout the shaft further indicate that the shaft was likely bent over an acute angle.The reported stent fracture was likely the result of retracting the stent system with the stent partially deployed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.Na.
