Abstract
A controlled delivery device for holding and administering a biologically active agent includes a housing having a first end portion, a second end portion, and a port associated with the housing. Enclosed within the housing is a displacing member, a chemical or electrochemical gas generating cell, activation and control circuitry. The electrochemical or chemical cell generates gas within the housing, forcing the displacing member against the beneficial agents contained within the housing and forcing the beneficial agents through an outlet port and into an animal's body cavity at a predetermined rate. An anchoring mechanism may be associated with the housing for securing the housing inside the body cavity of the animal being treated. Also disclosed are methods of delivering the beneficial agents into the animal's body cavity using the delivery device of the present invention.
