H10: manufacturing review: 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.Based on the information available it is not reasonably suggested that a manufacturing process may have caused or contributed to the reported issue.Investigation summary: the delivery system was returned for evaluation.The stent was found completely deployed and was included with the sample return.The handle of the delivery system was found disassembled upon sample receipt.A force transmitting component - the proximal catheter - was found to be broken, which is considered to be related to the reported impossibility to deploy the stent inside the patient.Based on evaluation of the sample breakage of a force transmitting component and the failure to deploy the stent in the patient is confirmed.However, no indication for a manufacturing related cause were found.Based on information available, a definite root cause for the reported event could not be determined.Labeling review: relevant labeling for this product was reviewed.The reported issue was found addressed, as the instructions for use states that delivery system specific events that could be associated with clinical complications include but are not limited to failure to deploy and high deployment forces.Regarding stent deployment, the instructions for use states: "maintain a stationary hold on the white stability sheath during covered stent deployment (¿).Hold the white stability sheath as close as possible to the introducer without touching the dark brown moving catheter of the distal catheter assembly.Maintain the remainder of the white stability sheath relaxed and avoid tension.Retraction of the distal catheter and deployment of the covered stent is initiated by rotating the large wheel on the handle." regarding preparation and accessories, the instructions for use states: "pre-dilate the stenosis with a pta balloon catheter of appropriate length and diameter for the lesion to be treated." and "0.035-inch (0.89 mm) guidewire of appropriate length (¿) introducer sheath with appropriate inner diameter and length." h10: d4 (expiry date: 06/2025) 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.
