1. A method of forming an implant in tissue, the method comprising:
providing a polymer solution having an effective amount of polymer dissolved in a biocompatible, water-soluble organic solvent;
injecting a plurality of droplets of the polymer solution in the tissue;
fusing the injected droplets together;
dissipating the biocompatible, water-soluble organic solvent in the tissue; and
precipitating the polymer from the injected polymer solution so as to form the implant.
