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.Investigation summary: the delivery system was returned for evaluation and the slide block, a force transmitting component was no longer connected to the proximal sheath.The disconnection of the slide block from the proximal sheath, can also be matched with the reported cracking sound.It is considered that the disconnection of the slide block led to the reported impossibility to deploy the stent and the freewheeling effect reported by the customer.Based on evaluation of the sample the inability of an adhesive joint (slide block/tether/diving sheath) to withstand tension force during deployment is confirmed.A definitive root cause could not be determined based upon the available information.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." 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: the catalog number identified in section d4 has not been cleared in the us but is similar to the covera plus vascular covered stent products that are cleared in the us.The pro code and 510 k number for the covera plus vascular covered stent products are identified in d2 and g4.H10: d4 (expiry date: 07/2023), g3, h6 (device).H11: g1, h6 (result).H11: section a through f - the information provided by bd represents all of 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.
