The incident information was reviewed; however, the product was not returned to abbott vascular for 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.The investigation determined the reported difficulties of difficulty to remove and stent dislodgement appear to be related to operational circumstances of the procedure.Based on the reported information, the selected device size chosen for the procedure was too short to cover lesion.During retraction, the sds encountered resistance with the anatomy and/or other devices used causing the stent to dislodge on the wire.Manipulation during attempt to retrieve the stent using a snare device caused the stent to get stuck on the previously implanted stent.Additionally, the treatment appears to be related to the operational context of the procedure as a non-abbott covered stent was used to cover the entire area and embed the dislodged stent to the vessel wall.There is no indication of a product quality issue with respect to the design, manufacture.
