Patent ID: 7927618

Claim:
A kit for the preparation of a composition comprising a carrier phase, which forms an implant or particles in a body, on a body or under physiological conditions, the kit comprising: a first container containing at least one solid or semisolid carrier material; and a second container containing an amount of solvent sufficient to dissolve the carrier material, wherein the carrier material is separate from the solvent; wherein the carrier material is sufficiently soluble in the solvent so that it dissolves in the solvent within less than 60 minutes, if placed in contact and mixed therewith, thereby rapidly forming an administrable carrier phase comprising a polymer solution; the carrier material is a powder or lyophile; the solvent comprises water and/or one or more water-miscible organic solvents when the carrier material is water soluble; the solvent comprises one or more organic solvents when the carrier material is water insoluble; and wherein the administrable carrier phase forms an implant or particles in situ after being placed in a body, on a body or under physiological conditions.
