Methods for treating aneurysms
First Claim
1. A method for treating an aneurysm in a mammalian patient which method comprises:
- (a) identifying the vascular site of an aneurysm in a mammalian patient wherein said aneurysm comprises an aneursymal sac formed from the vascular wall of a parent artery and further wherein said aneurysmal sac participates in the systemic blood flow of said patient;
(b) inhibiting systemic blood flow into said aneurysmal sac by filling at least a portion of said sac with a fluid composition and/or a non-particulate agent or plurality of said agents; and
(c) non-endogenously isolating the parent artery proximal and distal to said aneurysm from systemic blood flow by placement of a porous stent adjacent the aneurysmal sac wherein said stent extends in both the proximal and distal directions of the parent artery followed by addition of a sufficient amount of the fluid composition to the aneursymal sac to overfill said sac such that said excess amount of fluid composition encapsulates at least a portion of the porous stent both proximally and distally to the aneurysmal sac.

Abstract
This invention is directed to methods for treating aneurysms wherein the aneurysmal sac is filled with a non-particulate agent or plurality of such agents and/or with a fluid composition which solidifies in situ. Filling of the aneurysmal sac employs sufficient amount of the non-particulate agent or plurality of such agents and/or the fluid composition to inhibit blood flow into the aneurysm sac. In addition, the methods of this invention also provide for non-endogenous isolation of the parent artery proximal and distal to the aneurysmal sac from systemic blood flow of the treated mammal. The combination of these features provides for treatment of the aneurysmal sac while, at the same time, inhibiting aneurysm formation and/or regrowth in the diseased portions of the arterial wall proximal and distal to the treated aneurysm.
