29. A kit comprising in association:
-
a container of a liquid composition comprising a pharmaceutically acceptable, biodegradable liquid polymer dissolved in a biocompatible organic solvent that is dissolvable or dispersible in situ in a body fluid, and a biologically active agent; wherein the liquid composition, when placed in contact with body fluid, will form a polymeric implant having a liquid consistency which does not form into a solid in situ; and
the biologically active agent will be released into the body as the polymeric implant biodegrades within the body; anddirections for administration of the liquid composition to form the polymeric implant.
