Event Description

On (b)(6) 2024, the patient underwent endovascular procedure using a gore® excluder® aaa endoprosthesis to treat an abdominal aortic aneurysm.On (b)(6) 2024, the follow up scan showed that the device migrated distally and appeared to be flow limiting due to angle ¿ dynamically opening and closing.Reportedly, the aortic neck was angulated, and the physician believed that this angulation contributed to the event.On (b)(6) 2024, the patient has subsequently had a conformable cuff implanted which has resolved the issue.

Event Description

On (b)(6), 2024, the patient underwent endovascular procedure using a gore® excluder® aaa endoprosthesis to treat an abdominal aortic aneurysm.On (b)(6), 2024, the follow up scan showed that the device migrated 2cm distally to the fulcrum point on the inner curve and appeared to be flow limiting due to angle ¿ dynamically opening and closing.Reportedly, the aortic neck was angulated (unknown), and the physician believed that this angulation may contributed to the event.The physician couldn¿t understand the reason for movement ¿ the device was not undersized and angle appears adequate.Reportedly, no vessels were covered or occluded.On (b)(6) 2024, the patient has subsequently had a conformable cuff implanted which has resolved the issue.The patient tolerated the procedure and is doing well.

Manufacturer Narrative

B5: event description was updated.H.6.Code c19: a review of the manufacturing records for the device verified that the lot met all pre-release specifications.The device remains implanted and is not available for analysis.Images were sent to gore for analysis.Evaluation is in process.Further information will be provided.

Manufacturer Narrative

B6: imaging evaluation was added.Images were sent to gore and evaluated.C19: a review of the manufacturing records for the device verified that the lot met all pre-release specifications.The device remains implanted and is not available for analysis.According to the physician, the aortic neck was angulated (unknown), and this angulation may contributed to the event.According to the imaging evaluation, the abdominal aorta appears to be tortuous.Imaging cannot confirm migration, however, this finding does support the information provided.According to the gore® excluder® aaa endoprosthesis instructions for use (ifu), adverse events that may occur and / or require intervention or additional intraoperative procedure time include, but are not limited to component migration.Additional considerations for patient selection include but are not limited to patient¿s anatomical suitability for endovascular repair.Key anatomic elements that may affect successful exclusion of the aneurysm include severe proximal neck angulation, short proximal aortic neck at the arterial implantation sites, specifically the proximal aortic neck.The gore® excluder® aaa endoprosthesis is intended to exclude the aneurysm from the blood circulation in patients diagnosed with infrarenal abdominal aortic aneurysm (aaa) disease and who have appropriate anatomy: proximal aortic neck angulation = 60°.Morphology (tortuosity) should be compatible with vascular access techniques.Angiographic images are recommended pre-treatment to evaluate the length and tortuosity of abdominal aorta.
