Abstract:
The present invention is directed to absorbable microspheres comprising a copolymer formed from greater than 88 to about 99 mole percent ε-caprolactone or p-dioxanone, and about 1 to less than 12 mole percent of a different second monomer selected from the group consisting of glycolide, p-dioxanone, trimethylene carbonate and the lactides and combinations thereof, said microspheres having a particle size ranging from about 5 to 2,000 microns. Also described herein are a method for making such microspheres and formulations comprising such absorbable microspheres.
