Abstract:
A composition capable of embolizing an aneurysm at a vascular site comprising:(a) a biocompatible polymer at a concentration of from about 12 to about 50 weight percent based on the total weight of the composition; (b) a biocompatible contrast agent wherein a sufficient amount of said contrast agent is employed in said composition to effect visualization in vivo; and (c) a biocompatible solvent which solubilizes said biocompatible polymer wherein sufficient amounts of said polymer are employed in said composition such that, upon delivery to a vascular site, a polymer precipitate forms which embolizes said vascular site; and further wherein the biocompatible polymer has a molecular weight and/or concentration sufficient to impart to the composition a viscosity of at least about 150 cSt at 40Â° C.
