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 stent graft delivery system was returned for evaluation; the outer sheath was fractured, one of the stent struts was found perforating the outer sheath while the stent graft was partially deployed.Also, provided photos show the stent graft to be partially deployed after the event, the outer sheath fractured and one of the stent struts perforating the outer sheath.It is considered that fracturing and perforation of the sheath led to the impossibility to completely deploy the stent graft which leads to confirmed results.It was reported that a 7fr introducer sheath was used to predilate the access, a 0.035" guidewire was used, the device was flushed, there was no calcification or tortousity of the vessel and the device was placed in the straight section of the lumen during deployment attempts.Based on the provided information and the evaluation of the returned sample, the investigation is closed with confirmed result for sheath fracture, sheath perforation, and partial deployment.A definite root cause for the reported event could not be determined.The intended placement of the device to treat aneurysm represent off-label use.Labeling review: in reviewing the relevant labeling, it was found that the instructions for use sufficiently address the potential risks.The instruction for use state: 'if unusual resistance or high deployment force is encountered during stent graft deployment, abort the procedure, remove the delivery system and use an alternative device.' regarding preparation of the device the instruction for use state that "prior to loading the vascular system over a guide wire, both ports must be flushed with sterile saline (.).Flushing these lumens will also facilitate stent graft deployment".Regarding the anatomy of the placement site the instruction for use states: "prior to stent graft deployment (.), ensure that the proximal stent graft end is positioned in a straight section of the lumen to reduce the risk of increased deployment forces and possible failure to deploy".Regarding accessories the instruction for use states: "prepare a stiff 0.035" guidewire per its instructions for use and advance the guidewire under fluoroscopy to the target location.The use of an appropriately sized introducer sheath is recommended".The packaging pictograms indicate an introducer size of 10f and a 0.035" guidewire.The instruction for use states that "the safety and effectiveness of the device for use in the treatment of aneurysms and pseudoaneurysms have not been established".The intended use of this device to treat aneurysm indicate an off-label use.H10: b5, d4 (expiry date: 09/2024), g3, h6 (device) h11: h6 (method, result, conclusion) h11: section a through f ¿ the information provide 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.H3 other text : see h10.
