Manufacturer Narrative

H10: the catalog number identified in section d4 has not been cleared in the us but is similar to the lifestent vascular stent products that are cleared in the us.The pro code and 510 k number for the lifestent vascular 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 sample was returned for evaluation.The returned sample was found without stent that reportedly had been deployed; the proximal end of the oval tip was found with deformation that may indicate that the system was stuck on the stent upon removal.Provided images have a poor resolution so that single struts are not visible and strut fracture cannot be confirmed; however, the stent contour confirms stent twist.The images do not demonstrate difficult removal.The investigation leads to confirmed result for stent twist.The vessel was not tortuous/ calcified, the lesion was pre dilated, and the user did not experience difficulty during deployment.Based on the investigation of the provided information, the investigation is closed as confirmed for stent twisting.A definitive root cause for the reported event 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.The instructions for use closely describes holding and handling of the system during deployment; in particular the instructions for use state: 'confirm that the introducer sheath is secure and will not move during deployment.(¿) to ensure the most accurate placement, firmly hold the black system stability sheath throughout deployment.(¿) do not hold the silver stent delivery sheath at any time during deployment.Do not constrict the stent delivery sheath during stent deployment.Initiate stent deployment by rotating the thumbwheel in the direction of the arrows, while holding the handle in a fixed position.' regarding pta the ifu state: 'predilation of the lesion should be performed using standard techniques.' regarding access and accessories, the instructions for use states: 'gain femoral access utilizing a 6f (2.0 mm) or larger introducer sheath.Insert a 0.035inch (0.89 mm) diameter guidewire of appropriate length (.)'.H10: b5, d4 (expiry date: 01/2023), g3, h6 (device) h11: h6 (method, result, conclusion) 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.H3 other text : see h10.
