The present invention provides injectable, bioabsorbable microdispersions suitable for use as a soft tissue repair or augmentation material in animals comprising a fluid carrier that is a liquid polymer selected from the group consisting of liquid polymers of a plurality of at least two different first lactone repeating units and liquid polymers of a plurality of first lactone and second lactone repeating units; wherein the first lactone repeating units are selected from the group consisting of E-caprolactone repeating units, trimethylene carbonate repeating units, ether lactone repeating units (which for the purpose of this invention shall means 1,4-dioxepan-2- one and 1,5-dioxepan-2-one) and combinations thereof and the second lactone repeating units are selected from the group consisting of glycolide repeating units, lactide repeating units (which for the purpose of this invention is defined to be L-lactide, D-lactide, or D,L-lactide repeat units), p-dioxanone repeating units and combinations thereof; and a particulate material that is selected from the group consisting of solid homopolymers of poly(.epsilon.-caprolactone), solid homopolymers of poly(p- dioxanone), solid homopolymers of poly(trimethylene carbonate), solid copolymers of a plurality of .epsilon.- caprolactone repeating units and third lactone repeating units, solid copolymers of a plurality of trimethylene carbonate repeating units and second lactone repeating units; wherein the third lactone repeating units are selected from the group consisting of glycolide repeating units, lactide repeating units, trimethylene carbonate repeating units, p-dioxanone repeating units, 1,4- dioxepan-2-one repeating units, 1-5-dioxepan-2-one repeating units and combinations thereof. Additionally, the present invention also discloses methods of using these microdispersions for tissue augmentation and repair as well as kits which include prefilled containers to facilitate the use of these materials.
