Manufacturer Narrative

Block h2: additional information: block b5 (describe event or problem).Block h6: medical device code a0401 captures the reportable event of catheter break.Impact code f23 captures the reportable event of unexpected medical intervention.Block h10: investigation results the returned percutaneous locking loop nephrostomy catheter was analyzed, and a visual evaluation noted that the catheter was with bond around the proximal end.Additionally, the shaft was detached and had the suture entangled.Functional evaluation was performed, and it was found that the mandrel was able to pass through the stent without resistance.Microscopic examination was performed which confirmed the found problems.No other problems with the device were noted.A media analysis was performed to the photos submitted by the customer, and the first photo shows that the catheter was kink at the proximal end.Other photos show the catheter was detached from the shaft.The reported event of catheter break was confirmed.Investigation found that the catheter was kink, this is likely due to the interaction of the device, and handling/manipulation such as an excessive force applied over the device during the procedure, leading to the leakage found on the catheter.Additionally, the breakage reported is considered as part of the procedure.Taking all available information into consideration, the most probable cause of this complaint is adverse event related to procedure because the adverse event occurred during the procedure and the device had no influence on the event.Block h11: correction: block b5 (describe event or problem), h6 (impact code) and h10 (additional mfr narrative).
