METHOD AND DEVICE FOR TREATING ANEURYSMS

摘要

An apparatus and method for treating an aneurysm (23) in a vessel (20) that isolates a volume around the aneurysm, evacuates that volume and heats the aneurysmal wall (24). A catheter (31) includes one or more inflatable balloons (34, 35) for defining the isolated volume and occluding and preventing any blood flow through the volume. Suction applied through the catheter (31, 55) to the isolated volume withdraws any blood in the isolated volume and displaces the tissue for contact with a thermal source (50) that heats the aneurysmal wall. When the treatment is completed, the balloons are deflated and the catheter is removed from the vessel.
