The device was not returned for analysis.The lot history record and exception reviews were performed and revealed no indication of a product quality issue.Additionally, a review of the complaint handling database identified no other similar incidents from this lot.The absolute pro was advanced on a.018¿ guidewire.It should be noted the absolute pro vascular self-expanding stent system instructions for use (ifu), states: one 0.035" (0.89 mm) diameter guide wire.The deviation of the ifu appears to have contributed to the reported difficulties.As there was no damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to deviation of the instructions for use and subsequent circumstances of the procedure as it is likely that during advancement use of the undersized.018¿ guide wire in conjunction with interaction with the heavily tortuous and moderately calcified anatomy resulted in bending the device such that it prevented the shaft lumens from moving freely; thus resulting in the reported thumbwheel mechanical jam and the reported activation/deployment failure.Interaction with the heavily tortuous and moderately calcified anatomy resulted in the reported difficult to remove.Based on the reported information and results of the complaint investigation 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 in the external iliac artery with moderate calcification and heavy tortuosity.The 10x60mm absolute vascular pro self expanding stent system (sess) was advanced to the target lesion using the crossover approach on a.018 guide wire.During stent deployment the thumbwheel became stuck after 1 click and the stent was only able to be partially deployed.A.014 guide wire was advanced in an attempt to straighten the very tortuous anatomy; however, the thumbwheel remained jammed.The introducer sheath was pushed forward to collapse the deployed stent and the sess with the stent was removed from the anatomy.In the physician's opinion, the thumbwheel became stuck due to patient's very tortuous anatomy.Another absolute pro stent was used to complete the procedure.There was no adverse patient effect and no clinically significant delay reported in the procedure.No additional information was provided.
