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.

Claims

1. A vaginal insert for delivering an agent to a urogenital tract in a patient, the patient having a vagina, the vagina having a vaginal wall, the vaginal insert comprising:

an elongated base member sized to fit within the vagina, the base member defining a chamber and a port in fluid communication with the chamber; and

a membrane operatively connected to the elongated base member, the membrane surrounding at least a portion of the elongated base member, the membrane defining a reservoir and pores, the reservoir being in fluid communication with the port.

2. The vaginal insert of claim 1 further comprising a first and second electrodes, the first electrode being operably connected to the base member, the first and second electrode configured to be operably connected to a power supply.

3. The vaginal insert of claim 2 wherein the base unit has a surface and the first electrode is mounted on the surface.

4. The vaginal insert of claim 2 wherein the second electrode is operably connected to the base member thereby forming a bipolar electrode configuration.

5. The vaginal insert of claim 4 further comprising a power supply positioned within the base member, the power supply being operably connected to the first and second electrodes.

6. The vaginal insert of claim 5 wherein the power supply is an inductive circuit configured to generate an electric current when subjected to a magnetic field.

7. The vaginal insert of claim 1 further comprising an ultrasonic transducer operably connected to the base unit.

8. The vaginal insert of claim 1 wherein the membrane is a sheath having an open end, the sheath fitting over the base unit and the open end being sealed to the base unit thereby forming the reservoir.

9. The vaginal insert of claim 1 wherein the base unit defines a supply port in fluid communication with the chamber, the supply port being sealed by a septum the septum being configured to be pierced by a needle and configured to seal when the needle is withdrawn.
