Method for treating aneurysms with a thermal source
First Claim
1. A method for treating an aneurysm in the wall of a vessel defined by an aneurysmal wall with adjacent normal wall portions, said method comprising the steps of:
- A. isolating, with a percutaneously administered expansible means, a volume in the vessel around the aneurysm,B. reducing the pressure in the isolated volume through evacuating means carried with the expansible means thereby to evacuate the isolated volume and displace the aneurysmal wall,C. heating the aneurysmal wall with heating means carried with the expansible means thereby to thicken and strengthen the aneurysmal wall, andD. clearing the vessel by removing the expansible means, the evacuating means and the heating means.

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