ABSTRACT:
Disclosed are novel high viscosity compositions for embolizing blood vessels which comprise a biocompatible prepolymer and a contrast agent, and optionally a thickening agent and/or a biocompatible solvent. Also disclosed are methods for embolizing a vascular site by injecting high viscosity prepolymer compositions into said site. The disclosed compositions and methods are particularly well suited for the treatment of aneurysms.
