Abstract
A method of treating scar tissue by applying a composite sheet for delivering therapeutic agents to the skin is disclosed. The composite sheet comprises a flexible porous polymer for holding and releasing the therapeutic agent in a polymer enrobing material. Microchannels pass through the polymer enrobing material and flexible porous polymer to promote the release of the therapeutic agent. The composite sheet is capable of releasing the therapeutic agent for periods of about 0 to about 30 days.
