Abstract
This invention relates to a medical device and a method of using the device to deliver a continuous controlled supply of a medication to a specific internal site. Specifically, the invention comprises an inert, biodegradable implant impregnated with one or more therapeutic agents designed to provide a controlled, localized and sustained release of the therapeutic agents. In a preferred embodiment, the device comprises an ocular implant which bioerodes within the eye environment thereby gradually releasing the therapeutic agents at the site to be treated until the entire implant eventually erodes without the need for further surgery. The invention is especially suitable for treating post-operative glaucoma patients.
