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 common device name and pma/510k.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.Investigation summary: the delivery system was returned for evaluation, and the force transmitting proximal sheath was broken which indicates high tensile forces were experienced during deployment and the stent was partially deployed.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 misfire.A process related issue could not be found.There was no calcification/tortuosity but the lesion was not pre-dilated.Based on evaluation of the sample, the investigation is confirmed for break and misfire.A definite root cause could not be established based upon the available information.The use of this device to treat aneurysm represents off-label use.Labeling review: in reviewing the relevant labeling for this product the potential issue was found addressed.The instructions for use state: "pre-dilate the stenosis with a pta balloon catheter of appropriate length and diameter for the lesion to be treated", and "0.035 inch guidewire of appropriate length (.), introducer sheath with appropriate inner diameter" should be used; the packaging pictogram indicates the use of an 8f introducer.Holding and handling of the system throughout deployment was found sufficiently described.The instructions for use further states that "the safety and effectiveness of the device when placed across an aneurysm or a pseudo-aneurysm has not been evaluated".(expiry date: 01/2024).
