Abstract:
1. An aqueous dispersion consisting of a saline water solution and absorbable microspheres, wherein the absorbable microspheres comprise a copolymer formed from greater than 88 to about 99 mole percent epsilon-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, L-lactide, D-lactide, meso-lactide and combinations thereof, said absorbable microspheres having a diameter ranging from about 30 to about 75 microns, wherein said copolymer has a crystallinity level ranging from about 10 to 65% and a molecular weight of between about 1,000 to about 50,000 Daltons, and wherein said absorbable microspheres have dimensional stability and a distinct spherical shape, and when used intradermally are not palpable under skin.
