Abstract

Apparatus and method for treating a disease or condition of the ear, such as Meniere'"'"'s disease or endolymphatic hydrops, includes a manual device operable by hand to pressurize air and pressure transmitting arrangement for delivering the pressurized air to the middle ear, preferably in pulses, to displace the partition between the middle ear and the inner ear to influence fluid in the inner ear.

Claims

1. Apparatus for treating a human ear having an outer ear canal separated from a middle ear by a tympanic membrane with a vent therethrough and an inner ear separated from the middle ear by a partition to treat the symptoms of Meniere'"'"'s disease comprising

a manual device operable by hand to pressurize air;

and

pressure transmitting means communicating with said manual device and configured to communicate with the outer ear canal to deliver air pressure to the middle ear via the vent to displace the partition to influence fluid distribution in the inner ear.

2. The apparatus recited in claim 1 wherein said manual device includes a chamber having resilient walls and squeezable by hand to pressurize air therein.

3. The apparatus recited in claim 2 where said pressure transmitting means includes a reservoir communicating with said chamber for holding air pressure therein greater than ambient air pressure for delivery to the middle ear via the outer ear canal and the vent.

4. The apparatus recited in claim 3 wherein said pressure transmitting means includes means for delivering air pressure pulses to the middle ear via the outer ear canal and the vent.

5. The apparatus recited in claim 1 wherein said pressure transmitting means includes a passage delivering a static air pressure greater than ambient air pressure to the middle ear via the outer ear canal and the vent.

6. The apparatus recited in claim 5 wherein said pressure transmitting means includes means for generating air pressure pulses superimposed on said static air pressure to be delivered to the middle ear via the outer ear canal and the vent.

7. The apparatus recited in claim 1 wherein said pressure transmitting means includes means for delivering air pressure pulses to the middle ear via the outer ear canal and the vent.

8. The apparatus recited in claim 1 wherein said pressure transmitting means includes a plug for engaging the inner ear canal and an aperture in the plug.

9. Apparatus for treating a human ear having an outer ear canal separated from a middle ear by a tympanic membrane with a vent therethrough and an inner ear separated from the middle ear by a partition to treat the symptoms of Meniere'"'"'s disease comprising

a hand-operated, manual air pressurizing device including a chamber, a first check valve in a first port communicating with said chamber allowing air to enter said chamber and preventing air from exiting from said chamber and a second check valve in a second port communicating with said chamber allowing air to exit said chamber and preventing air from entering said chamber;

and

a pressure transmitting arrangement communicating with said second port of said hand-operated manual air pressurizing device receiving pressurized air from said chamber and configured to communicate with the inner ear to deliver the air pressure to the middle ear via the vent to displace the partition to influence fluid in the inner ear.

10. The apparatus recited in claim 9 wherein said pressure transmitting arrangement includes a reservoir to establish a static air pressure greater than ambient air pressure for delivery to the middle ear via the outer ear canal and the vent.

11. The apparatus recited in claim 10 wherein said pressure transmitting structure includes a pressure regulator forming pressurized air pulses superimposed on said static air pressure for delivery to the middle ear via the outer ear canal and the vent.

12. The apparatus recited in claim 11 wherein said pressure transmitting structure includes a check valve disposed between said reservoir and said pressure regulator allowing air to enter said pressure regulator from said reservoir and preventing air from said pressure regulator from entering said reservoir.

13. The apparatus recited in claim 12 wherein said pressure regulator includes a pivotally mounted valve member forming said pressurized air pulses.

14. The apparatus recited in claim 13 wherein said manual air pressurizing device has resilient walls squeezable by hand.

15. A method for treating a human ear having a middle ear and an inner ear separated by a partition to treat the symptoms of Meniere'"'"'s disease comprising the steps of

manually pressurizing air;

and

delivering the manually pressurized air to the middle ear to displace the partition to influence fluid distribution in the inner ear.

16. The method recited in claim 15 wherein said manually pressurizing step includes manually squeezing a resilient chamber.

17. The method recited in claim 15 wherein said delivering step includes delivering the pressurized air to the middle ear in pulses.

18. The method recited in claim 17 wherein said delivering step includes establishing a static air pressure in the middle ear greater than ambient air pressure and superimposing the pressurized air pulses on the static air pressure.
