Block h6: imdrf device code a0401 captures the reportable event of stent shaft broken.Correction to device and component code: additional information received that the stent coil was detached.Block h10: the returned percuflex plus ureteral stent was analyzed, and a visual evaluation noted that the bladder coil was detached.The suture, positioner and the detached part was not returned, however their respective axxcess catheter and guidewire inside their original pouches were in good condition.A functional test was performed and used a mandrel of 0.039" and the stent pass through without resistance.During magnification, it was observed closely that the section of the device was detached.No other problems with the device were noted.The reported event was confirmed.Based on the most relevant information of the complaint event description, device analysis and including the product record review results, the device meets all manufacturing specifications required and passed all the controls and inspections, no abnormalities were reported during the assembly process.According to the evidence, it is possible that operational factors, interaction of the excess force during interaction with the suture string such as an entanglement before their use could have caused the detachment that was observed.Consequently, affect 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.
