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: based on the information available it is not reasonably suggested that a manufacturing process may have caused or contributed to the reported issue.However, 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 sample was not returned for evaluation.X-ray images and videos were provided for both tied complaints demonstrating patient treatment.Single stent struts are not visible due to poor image quality so that a stent fracture cannot be confirmed.Strut irregularity is visible on the stent in distal position which leads to confirmed result for stent strut deformation.A closer description is not possible due to poor image quality.A 8f introducer with 0.035" guidewire were used for access, the vessel was not tortuous/calcified, and the lesion was pre and post dilated.The system was correctly held at the stability sheath, the user did not experience difficulty during deployment, and there was no irregularity observed in the stent strut structure.Based on the investigation of the provided information, the investigation is closed as confirmed for stent deformation.A definite root cause for the reported event could not be determined.Labeling review: in reviewing the relevant labeling for this product, the potential issue was found addressed.The instructions for use closely describe holding and handling of the system for regular deployment, in particular the instructions for use state: 'confirm that the introducer sheath is secure and will not move during deployment.Firmly hold the black system stability sheath throughout deployment.Do not hold the silver stent delivery sheath.Do not constrict the stent delivery sheath during stent deployment'.In regard to pta the instructions for use state: 'predilation of the lesion should be performed using standard techniques' and 'post stent expansion with a pta catheter is recommended'.In regard to access and accessories the instructions for use state: 'gain femoral access utilizing a 6f (2.0 mm) or larger introducer sheath.Insert a 0.035 inch (0.89 mm) diameter guidewire'.The instructions for use further state: 'cases of fracture have been reported in clinical use of the lifestent vascular stent in lesions that were moderate to severely calcified, proximal or distal to an area of stent overlap and in cases where stents experienced >10% elongation at deployment.Therefore, care should be taken when deploying the stent as manipulation of the delivery system may, in rare instances, lead to stent elongation and subsequent stent fracture'.Stent fracture was found mentioned as a potential adverse event that may occur.H10: d4 (expiration date: 05/2025), g3, h6 (device) h11: b5, h6 (method, result, conclusion) 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.

Event Description
