It was reported that the procedure was to treat a lesion located in the superficial femoral artery that was moderately calcified and mildly tortuous.After lesion preparation, the supera stent system was advanced to the lesion and stent deployment initiated; however, the stent did not fully deploy and would not release from the device.The supera stent system, including the stent were removed without issue.There was no reported adverse patient effect and no clinically significant delay in the procedure.A new supera stent was implanted, without issue, to complete the procedure.No additional information was provided.

Visual analysis was performed on the returned device.The reported deployment difficulty and partial stent deployment were not confirmed as the stent was not returned and had already been fully deployed.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 of the reported lot revealed no other complaints.The investigation was unable to determine a cause for the reported difficulties.It may be possible that the distal sheath of the delivery system was entrapped or bent within the anatomy preventing the ratchet from engaging the stent during the final deployment stroke; however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.Na.
