NOVEL EMBOLIZING COMPOSITIONS

摘要

Disclosed are novel compositions for embolizing blood vessels which are particularly suited for treating vascular lesions via catheter delivery. In one embodiment, the compositions of this invention comprise a biocompatible polymer, a biocompatible solvent and a biocompatible water insoluble contrast agent characterized by having an average particle size of less than about 10 .mu.m. In another embodiment, the biocompatible polymer in these compositions is replaced with a biocompatible prepolymer.
