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 stent delivery system was returned for evaluation and the stent was still loaded in the delivery system and in place.The delivery system was detached from the handgrip at the level of the conversion tab, which was missing but however, still secured by the stabilizer.The trigger mechanism was activated, and the slider moved proximally, and the inner catheter was protruding.During testing on the bench, the stent could be deployed by retraction and pulling.It is considered that the detachment of the delivery system led to the eventual failure to deploy the stent using the trigger which leads to confirmed results.Based on analysis of the returned sample, the investigation is closed with confirmed results for detachment and "failure to deploy" is considered to have been a cascading event.A definite root cause for the reported event could not be determined.Labeling review: in reviewing the relevant labeling, it was found that the instructions for use sufficiently address the potential risks.With regards to general warnings, the instructions for use states that "should unusual resistance be felt at any time during the procedure, the entire system (introducer sheath or guiding catheter and stent delivery system) should be removed as a single unit".Regarding accessories, the instructions for use states "the bard s.A.F.E.R 6f delivery system requires a minimum 8f guiding catheter or a minimum 6f introducer sheath" also "via the femoral route, insert a 0.035¿ (0.89 mm) guide wire under fluoroscopic guidance through the appropriate introducer sheath or guiding catheter and pass the lesion".The packaging pictograms indicate an introducer size of 6f and a 0.035" guide wire.The instructions for use mentions "damage or detachment of a component of the system" as potential malfunctions and adverse effects.H10: d4 (expiration date: 08/2025).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.
