This invention discloses methods and composition to form biodegradable polymer implant arrays in the live tissue. Artificial cavities are created in the live tissue by using laser ablation, oscillating needle, microneedle array and other methods. The cavities are then filled with biodegradable polymer solution. The solvent in the polymer solution is dissipated in the tissue to form a biodegradable polymer implant in artificial cavities. The cavities and implants formed are arranged to form of an array of implants. The biodegradable polymer in the cavity can also be loaded with drug to form biodegradable drug delivery array in the live tissue.
A method of making a sustained biodegradable implant in a tissue, the method comprising:
The method according to claim 9, wherein injectable composition comprises a polymer dissolved in an aqueous solution.
The method according to claim 10, wherein the polymer shows a thermoreversible property in the aqueous solution and is selected from a group consisting of polymers or copolymers of:
