Event Description

The following details were reported to gore: device only deployed half way.Snapped off catheter.Fsa sending back cath & drawstring.Left partially deployed converted to qui fem fem bypass.

Manufacturer Narrative

The device delivery catheter was returned to gore and an evaluation showed the following: the leading end of the catheter (polyimide guidewire lumen) had separated from the catheter body at the trailing olive.The polyimide guidewire lumen had pulled out of the trailing olive bond on the catheter.There was material from the polyimide guidewire lumen inside the trailing olive indicating that the olive had been bonded to the polyimide guidewire lumen.No knots or obstructions were noted on the returned portion of the deployment line.The deployment line had frayed at the end, which is indicative of a tensile break.The length of the deployment line attached to the deployment knob, which appeared to be as long as the catheter, indicates the deployment line broke near the end of the device.The deployment line was sent for scanning electron microscopy (sem) imaging.The sem imaging further indicated that the deployment line fiber experienced tensile stress prior to breakage.The provided image showed that the last 5cm of the contralateral leg of the device did not deploy.The findings from the evaluation are consistent with the reported observation.The likely cause for the break in the deployment line and that the device was not fully deployed could not be determined with the currently available information.The likely cause for the leading end of the catheter (polyimide guidewire lumen) separation could not be determined with the available information.

Event Description

On (b)(6) 2023, this patient underwent endovascular treatment for a zone 9- infrarenal abdominal aortic aneurysm measuring 7cm in diameter.Additionally, the patient was reported to have a highly angulated neck (degree unknown) and a dissection that extended from the left subclavian artery all the way to the renal arteries.The patient was implanted with gore® excluder® conformable aaa endoprosthesis.It was reported that the trunk ipsilateral leg endoprosthesis was advanced up the left side and landed just fine below the lowest renal artery and avoiding the area of dissection.The physician came up the left side to cannulate the gate however there was some angulation of the gate due to the size of the aneurysm.A couple of tries were made before successful cannulation of the gate was achieved and a contralateral leg component advanced was deployed; however halfway into deploying the just deployment line just ¿locked up¿.The looked under fluoroscopy to see if they could determine a cause of the stuck deployment line as the device was already halfway deployed, but were unable to determine a cause.As they were unable to advance a balloon catheter from the top due to the dissection and or from the other side, to maneuver inside the flow divider, the physician was left with no choice but to pull as hard as he could which caused the deployment line to snap.The physician then really pulled down on the device and the leading end of the catheter broke off at the polymide and leading olive and were unable to be retrieved and remain in the patient.The patient was then converted to open and an aorta uni iliac (aui) and fem fem bypass was performed.The patient tolerated the procedure.
