The reported event is inconclusive due to insufficient information.The ureteral stent was returned in the opened original packaging along with the unopened guidewire.An evaluation of the physical sample was completed by futurematrix on 23may2023.The provided photo could not be evaluated for the reported event.Visual evaluation of the physical sample noted to defects.The suture and pigtail straightener were not provided for evaluation.The sample passed dimensional requirements per cd-7068-xx; the outer diameter was measured at 0.0801" using a laser micrometer, the tip inner diameter measured 0.043" using a pin gauge.A 0.038" guidewire successfully passed through the sample with no resistance.Though no defects were noted on the returned sample, as the patient's anatomy is unknown, unable to determine the ease of insertion while using the stent.A potential root cause for this event could be, "material selection".No manufacturing issues or non-conformances were noted during review of the dhr that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: "the insertion of a ureteral stent should only be done by those individuals who have comprehensive training in the techniques and risks of the procedure." "directions for use: 1.Determine the proper stent length for the patient.This is generally calculated from the baseline pyelogram.Accurate measurements will optimize drainage efficiency and patient comfort.Submerge stent in sterile water to activate the coating.2.Insert the cystoscope then pass the guidewire* through the scope until the tip is in the renal pelvis.3.Move the pigtail straightener over the proximal end (kidney coil end) of the ureteral stent allowing easier insertion onto the guidewire.Remove pigtail straightener once the stent is secure on the guidewire.4.Pass the stent over the guidewire through the cystoscope by using the push catheter for proper placement.5.Watch the distal end (bladder coil end) of the stent or the radiopaque, proximal end of the pusher.Stop advancing when the stent¿s distal end marker reaches the ureterovesical junction (uvj).6.Withdraw the guidewire slowly.The stent will form a pigtail automatically.7.Carefully remove the push catheter." "*activate the guidewire coating according to the ¿instructions for use¿ found within the guidewire packaging." corrections: h11: section a through f - the information provided by bd represents all the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.H3 other text : the actual/suspected device was inspected.
