Visual and functional analysis was performed on the return device.The device was returned with contrast on the balloon and in the inflation lumen.The balloon was tightly folded.There were crimp marks on the balloon and between the markers where the stent implant was initially crimped on.There was no damage noted to the balloon.The balloon inflated and held pressure with no anomalies noted; therefore, the reported inflation issue was not confirmed; however, as the stent was not received, the reported stent dislodgment was 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 complaints reported from this lot.Based on the information provided, a definitive cause for the reported difficulties could not be determined.It may be possible that the distal shaft of the omnilink elite was kinked or collapsed in the anatomy causing inflation difficulty resulting in stent dislodgment; however, this could not be confirmed.The additional treatment and minor surgical intervention to remove the stent were due to case circumstances.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

It was reported that the procedure was to treat a lesion located in the subclavian artery.The omnilink stent balloon opened only at its proximal end, pushing the stent distally off the balloon.The balloon did not open on both ends at the same time.The stent was able be navigated, via catheter, to the superficial femoral artery, where it was successfully removed with minor surgical intervention.The patient remained stable.The stent was replaced by another omnilink to complete the procedure.No additional information was provided.
