Abstract:
Apparatus for treating an aneurysm in the wall of a vessel having a vessel lumen and a bifurcation, said vessel being defined by an aneurysmal wall with adjacent normal wall portions, said apparatus comprising:a. catheter member having a catheter distal end for being guided through the vessel to the site of the aneurysm,b. expansible balloon member mounted to said catheter distal end of said catheter member for expansion into the normal wall portions upon expansion said balloon member forms a closed, isolated volume in the vessel lumen around the aneurysm,c. suction member for deforming the aneurysmal wall toward said catheter member, said suction member including a suction lumen in said catheter member, said suction lumen having a proximal end and a distal port, said distal port of said suction lumen in communication with the closed, isolated volume, said isolated volume being adjacent to the bifurcation of the vessel, said suction member being responsive to the application of a vacuum at the proximal end of said suction lumen for evacuating the closed, isolated volume and displacing the aneurysmal wall toward said catheter member, andd. heating member mounted to said catheter distal end of said catheter member at the closed, isolated volume for heating the aneurysmal wall thereby to thicken and strengthen the aneurysmal wall and treat said aneurysm.
