Event Description

Subsequent to the initially filed reports, additional information was provided: it was reported the procedure was to treat a highly tortuous and calcified arteria mesenterica inferior.The lesion was pre-dilated with a 3mm balloon.The 4.50x30mm supera self expanding stent system (ses) was advanced with resistance noted with the introducer sheath.The stent was deployed successfully.During removal, the thumbslide was not fully retracted to the start position.Resistance was met with the anatomy and the tip of the ses detached.A second supera of the same size was advanced however could not pass through the first implanted stent.During removal resistance was met and the tip separated and the stent came out of the sheath.The stent was able to be removed.Attempts were made to snare both separated tips but were unsuccessful and the tips remain in the patient anatomy.No additional information was provided.

Manufacturer Narrative

The device was returned for analysis.The reported material separation was able to be confirmed.The reported difficult to advance- introducer sheath was unable to be replicated in a testing environment due to the condition of the returned device.The reported difficult to advance-crossability and the reported difficult to remove were unable to be replicated in a testing environment as they were based on operational circumstances.Electronic lot history record (elhr) 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 circumstances of the procedure and subsequent deviation of the instructions for use as it is likely that during advancement interaction with introducer sheath resulted in the reported difficult to advance.After successfully deploying the stent, during device removal interaction with the highly tortuous and calcified anatomy in conjunction with not fully retracting the thumbslide to the start position per the instructions for use resulted in the reported difficult to remove and ultimately resulted in the reported tip material separation/noted tip jacket and inner member separations.As reported, attempts were made to snare the separated tip but were unsuccessful and the tip remains in the patient anatomy.Reportedly, during removal the thumbslide was not fully retracted to the start position.It should be noted that the supera peripheral stent system instructions for use (ifu) states: following confirmed implantation of the supera stent, retract the thumb slide in a single motion to the starting position on the handle and rotate the system lock and deployment lock into the locked position, in line with the thumb slide.As the deviation of the instructions for use appears to have caused/contributed to the reported difficulties the deviation will be addressed in the account requested letter.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.
