Abstract
A device useful for the treatment of infections of the middle ear in a prophylactic manner. A preferred device involves the use of a biodegradable support incorporating a therapeutically active agent, such as a drug. The device can be surgically inserted into the middle ear and there expand in order to substantially contact the walls of the middle ear. As it biodegrades, the expanded device provides prolonged, responsive release of active agent to the middle ear.
