Claim:
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 aneurysmal 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 optionally 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 wherein the fluid composition comprises a biocompatible polymer, a biocompatible contrast agent, and a biocompatible solvent which solubilizes the biocompatible polymer having a viscosity of at least 150 cSt at 40° C.
