Abstract
The present invention is directed to a vaginal insert for delivering an agent to a urogenital tract in a patient. The patient has a vagina, and the vagina has a vaginal wall. The vaginal insert comprises a base member sized to fit within the vagina, the base member defines a chamber and a port in fluid communication with the chamber. A membrane is operatively connected to the base member. The membrane defines a reservoir and a pore. The reservoir is in fluid communication with the port. The membrane is sized so that the vaginal wall will exert pressure against the membrane when fluid is in the reservoir, thereby forcing some of the fluid to flow through the pore and to tissue of the urogenital tract.
