Manufacturer Narrative

H10: the catalog number identified in section d4 has not been cleared in the us but is similar to the covera vascular covered stent products that are cleared in the us.The pro code and 510 k number for the covera vascular covered stent products are identified in d2 and g4.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 and the covered stent was found partially deployed; the force transmitting proximal sheath was broken which indicates high tensile forces were experienced during deployment.It is considered the break of the proximal sheath led to the impossibility to completely deploy the stent which leads to confirmed results for break and partial deployment (misfire).A photo was provided which show the covered stent partially deployed.Based on analysis of the provided photo and the evaluation of the returned sample, the investigation is closed with confirmed results for break and partial deployment.A definite root cause for the reported event could not be established.Labeling review: in reviewing the relevant labeling for this product, the potential issue was found addressed.Based on the instructions for use supplied with this product 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 correct 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".Based on the instructions for use material required for a procedure using the covera vascular covered stent are 0.035 inch guidewire of appropriate length, introducer sheath with appropriate inner diameter.Regarding preparation 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." h10: d4 (expiration date: 08/2024) 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.
