The device was not returned to abbott vascular for analysis.Return of the stent delivery system (sds), and inflation device may have further aided the analysis.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 reported from this lot.Factors that may contribute to difficulty inflating the device or stent deployment issues may include, but are not limited to, manufacturing, bent/kinked shaft while inside the anatomy, contamination in the inflation lumen, patient anatomical morphology, patient disease state, inflation/deflation technique, contrast solution, inadequate connection to the inflation device, and/or accessory device support.To help ensure this difficulty is not related to a manufacturing issue, all stent delivery systems (sds) are visually inspected for damage in manufacturing.The investigation was unable to determine conclusive cause for the reported stent deployment issue as the device was not returned for analysis.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 omnilink elite vascular balloon-expandable stent system was used during renal artery stenting.During attempted stent deployment at the lesion, the balloon was only minimally inflated, but failed to fully inflate.The stent was not deployed, remained secure on the balloon and was removed with the stent delivery system without issue.There was no reported adverse patient effect and no clinically significant delay in the procedure.Another device was used to stent the lesion.No additional information was provided.
