Embolization with Polyhydroxybutyrate (PHB) Microspheres: In-Vivo Studies

Journal of Bioactive and Compatible Polymers, 1999
In this study polyhydroxybutyrate (PHB), produced by a methanol-utilizing bacteria, was used to prepare microspheres in the 120-200 μm size range for embolization. A solvent evaporation technique was utilized to obtain microspheres in which methylene chloride, distilled water and polyvinyl alcohol were used as the solvent, precipitation medium and ...
