Gas generating device for delivering beneficial agents to a body cavity
First Claim
1. A method of delivering a beneficial agent into a body cavity of a being comprising the steps of:
- providing an apparatus including an enclosure having a volume and at least one chamber, each such chamber having a self-contained gas generating cell integrally associated therewith, said volume containing the beneficial agent, and an outlet port configured so as to permit passage of the beneficial agent from within the apparatus;
inserting the apparatus within a body cavity;
activating a gas generating cell and, in turn, generating a gas to create sufficient force against the beneficial agent; and
controllably forcing the beneficial agent out of said enclosure via the outlet port in fluid communication with a body cavity, thus dispersing the beneficial agent into a body cavity.

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.
