Event Description
|
It was reported to boston scientific corporation that a percuflex plus ureteral stent was used during a procedure, performed on (b)(6) 2022.During preparation, when the physician attempted to insert the stent into the patient, it could not be inserted due to there was no stiffness at the tip.Another perculfex plus ureteral stent was opened and successfully completed the procedure.There were no patient complications reported as a result of this event.

Initial reporter address 1: (b)(6).(b)(4).The returned percuflex plus ureteral stent was analyzed, and a visual evaluation noted that the bladder pig tail was buckled accordion.The suture and positioner was not returned.Both coils look in good condition and they still having their original shape.During the functional analysis, a use of a mandrel of 0,036" passed through the stent without resistance.Proceeded to perform a dimensional test which passed successfully in a measurement of stent length ("l-1") with 26cm.Finally, during magnification it was observed closely that it was buckled accordion on the bladder pig tail and it was observed there were several drag marks in the bladder pig tail.Also was possible observed that several side port holes are stretch out in both pig tails.No other issues noted to the device.The reported event was not confirmed.According to the product analysis, it was found that a bladder pig tail was buckled accordion and observed that side port holes of both pig tails (bladder and renal) were stretched out.Regarding with found issues, bladder pig tail buckled accordion and side port holes stretch out is possible that happened during the interaction with the positioner/pusher, excess of force applied to the stent such as operational factors during it use in the preparation, it could have caused the found issues.Consequently, affect the performance of the device.Therefore, adverse event related to procedure is selected as the most probable root cause for the complaint.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.

Block e1: initial reporter address 1: chuo-ku kita-nagasa-dori 5-7-17 block h6: medical device problem code a040601 captures the reportable investigation result of stent buckled material.Block h10: the returned percuflex plus ureteral stent was analyzed, and a visual evaluation noted that the bladder pig tail was buckled accordion.The suture and positioner was not returned.Both coils look in good condition and they still having their original shape.During the functional analysis, a use of a mandrel passed through the stent without resistance.Proceeded to perform a dimensional test which passed successfully in a measurement of stent length ("l-1") with 26cm.Finally, during magnification it was observed closely that it was buckled accordion on the bladder pig tail and it was observed there were several drag marks in the bladder pig tail.Also, it was possible to observe that several side port holes were stretched out in both pig tails.No other issues noted to the device.The reported event of coil memory was not confirmed.According to the product analysis, it was found that a bladder pig tail was buckled accordion and observed that side port holes of both pig tails (bladder and renal) were stretched out.Regarding with found issues, bladder pig tail buckled accordion and side port holes stretch out is possible that happened during the interaction with the positioner/pusher, excess of force applied to the stent such as operational factors during it use in the preparation, it could have caused the found issues.Consequently, affect the performance of the device.Therefore, adverse event related to procedure is selected as the most probable root cause for the complaint.Block h11: correction to block h6: device codes.
