Additional Manufacturer Narrative
Block h6: imdrf device code a0401 captures the reportable event of stent shaft broken.Block h10: the returned polaris loop ureteral stent was analyzed, and a visual and microscopic evaluation noted that the shaft was detached.Additionally, the suture and positioner were not returned.No other problems with the device were noted.Taking all available information into consideration, most likely, it is possible to conclude that this problem could be caused by operational factors.The retrieval line may be removed before placement at the physicians discretion.If the retrieval line is removed using excess force and entangled in the shaft, the stent can get detached during the preparation affecting the performance of the device.Therefore, all compiled information on this investigation determines that the most probable cause is adverse event related to procedure since the adverse event occurred during the procedure and the device had no influence on event.
