The device was returned for analysis.The reported activation failure was able to be confirmed.Production record and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a review of the complaint handling database identified no other incidents from this lot.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 as it is likely that use of the undersized 0.014¿ spartacore guide wire resulted in the noted stent sheath kink preventing the shaft lumens from moving freely thus resulting in the reported/noted activation failure.It should be noted the absolute pro self-expanding stent system instructions for use states: one (1) 0.035" (0.89 mm) diameter guide wire.Use of an undersized guide wire, with insufficient support, may cause kinking in the stent delivery system.As the deviation of the instructions for use likely caused/contributed to the reported difficulties an in-service letter to the physician will be required.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.H6 medical device problem code: 2017 - failure to follow steps / instructions.
