It was reported that during a stent placement procedure in the left superficial femoral artery via common femoral access, the guidewire allegedly felt resistance when advanced inside the delivery system and then the stent was delivered and removed successfully.It was further reported that there was an unknown object was found in the artery and when the delivery system was verified it was allegedly found that the tip of the delivery system was missing.Reportedly, while removing the tip using a snare, a thrombus was released and tpa was administered.The current status of the patient was unknown.

H10: manufacturing review: based on the information available it is not reasonably suggested that a manufacturing process may have caused or contributed to the reported issue.However, the lot history records of this lot were reviewed with special attention to the manufacturing and inspection of this product and the product was found to have met the specification prior to shipment.Investigation summary: the sample was returned for evaluation.The returned sample was found in used condition without stent and the inner catheter cardan tube was found broken twice at the distal end which leads to confirmed result for catheter break.Images demonstrating the detached pieces inside patient were not provided.A 5f introducer with 0.035" guidewire were used for access, the vessel was not tortuous but calcified, the lesion was pre dilated, and the user did no experience difficulty during deployment action.The system was correctly held at the stability sheath, and a sudden force increase was not felt during removal but the guidewire was running roughly inside the system.Therefore, based on the information available the investigation is closed with confirmed result for inner catheter break.A definite root cause for the reported event could not be determined.Labeling review: in reviewing the relevant labeling for this product, the potential issue was found addressed.The instructions for use states: 'do not constrict the delivery system during stent deployment.If excessive force is felt during stent deployment, do not force the stent system.Remove the stent system and replace with a new unit.' regarding pre dilation the instructions for use states: 'pre-dilatation of the lesion with a balloon dilatation catheter is recommended.' under materials required the instructions for use states: '5f (1.67 mm) or larger introducer sheath (¿); 0.014-inch (0.36 mm) - 0.035-inch (0.89 mm) diameter guidewire'.Regarding insertion and removal difficulty of the delivery system the instructions for use states: 'if resistance is met during stent system introduction, the stent system should be withdrawn and another stent system should be used.', and 'if resistance is met while retracting the delivery system over a guidewire, remove the delivery system and guidewire together.' holding and handling of the system throughout deployment was found sufficiently described.H10: d4 (expiry date: 07/2025), g3, h6 (method) h11: h6 (result, conclusion) h11: section a through f: the information provide 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 : see h10.
