(b)(4).During processing of this complaint, attempts were made to obtain complete event, patient and device information.The device was not returned for analysis.However, it may be possible that the distal sheath was restricted or entrapped within the anatomy such that when the sheath finally released, and the stent deployed, the stent jumped due to the built up tension within the shaft lumens of the delivery system causing a spring like release of the stent.A review of the lot history record revealed no non-conformances that would have contributed to the reported event.A query of the electronic complaint handling database revealed no other incidents reported from this lot.The investigation was unable to determine a cause for the reported inaccurate delivery.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 distal are of the iliac artery.The 7.0/100 mm absolute pro was advanced to the lesion and deployment of the stent was started; however, the catheter jumped forward.The device was repositioned and deployment was continued; however, severe resistance was felt during deployment with the catheter which resulted in the stent implant deploying partially in the lesion.The procedure continued on with the deployment of two additional absolute pro stents.No adverse patient effects or clinically significant delay in the procedure were reported.No additional information was provided.
