Abstract:
A method for sealing endoleaks in a patient arising from endovascular repair of abdominal aortic aneurysms in said patient which method comprises:identifying an abdominal aortic aneurysm in a patient; endovasularly repairing said aneurysm by catheter delivery of an endovascular prosthesis to the site of said aneurysm thereby inhibiting blood flow into the aneurysm; identifying one or more endoleaks in said patient treated for an abdominal aortic aneurysm with an endovascular prostheses wherein said endoleak occurs at the interface of the arterial wall and the end of the prosthesis or from defects within the prosthesis; and delivering through a microcatheter to the site or sites of said endoleaks in said patient a sufficient amount of fluid composition comprising a biocompatible solvent and ethylene vinyl alcohol copolymers, wherein the fluid composition forms a coherent mass in situ which adheres to the walls of the vascular site and/or prosthesis thereby sealing the endoleaks.
