(b)(4).Review of device manufacturing record history confirmed device met pre-release specifications.Device was discarded at user facility.Therefore, direct product analysis was not possible.Warnings section of ifu states: do not withdraw the gore® viabahn® endoprosthesis back into the introducer sheath once the endoprosthesis is fully introduced.Withdrawing the gore® viabahn® endoprosthesis back into the sheath can cause damage to the endoprosthesis, premature deployment, deployment failure, and / or catheter separation.If removal prior to deployment is necessary, withdraw the gore® viabahn® endoprosthesis to a position close to but not into the introducer sheath.Both the gore® viabahn® endoprosthesis and introducer sheath can then be removed in tandem.After removal, do not reuse the gore® viabahn® endoprosthesis or introducer sheath.

Patient presented for an aaa procedure and treatment in the right internal iliac artery.As reported to gore, the patient's vessels were heavily calcified with a very tortuous anatomy.Using.035 amplatz guidewire and a 12fr sheath, the gore® viabahn® endoprosthesis was advanced up and over the bifurcation.The gore® viabahn® endoprosthesis was unable to be advanced to the intended treatment site.Decision was made to remove the gore® viabahn® endoprosthesis and attempts were made to pull the gore® viabahn® endoprosthesis back into introducer sheath.As it was pulled back, the gore® viabahn® endoprosthesis got stuck inside the sheath because the gore® viabahn® endoprosthesis became distorted and compressed.The sheath and gore® viabahn® endoprosthesis had to be removed together.When the introducer sheath was removed, the constrained gore® viabahn® endoprosthesis was left behind in the left common femoral artery.A surgical cut-down was performed to remove the damaged gore® viabahn® endoprosthesis.The patient was reported to be doing well after the procedure.
