Implantable hearing aid
First Claim
1. An apparatus for enhancing hearing, which apparatus is insertable at least partially through a tympanic membrane of a user, comprising:
- a) a microphone;
b) an amplifier coupled to the microphone;
c) a speaker coupled to the amplifier, the microphone, the amplifier and the speaker being connected to each other into a single unit.

Abstract
The present invention provides an apparatus and method for inserting a relatively compact hearing aid at least partially through the tympanic membrane using a simplified surgical procedure. The hearing aid includes a microphone, an amplifier, and at least one speaker that can be assembled into a single enclosure for insertion through the tympanic membrane. The simplified surgical procedure can be performed on an outpatient basis and generally includes anesthetizing a portion of the tympanic membrane, forming an incision with a cutting instrument in the tympanic membrane and inserting the hearing aid at least partially therethrough. Incisions and placement of a tube in an tympanic membrane for car drainage is routinely performed in pediatric patients and combines low morbidity and good patient tolerability. The tympanic membrane restrains the hearing aid in position for at least a period of time. A power source, such as a battery, powers the hearing aid. Further, a receiver may be included with the hearing aid and can control the hearing aid from external sources. The receiver can control the amplified volume, receive sound transmissions from the opposite ear or a hearing aid in the opposite ear or receive personal communications.

18. The method of claim 12, further comprising placing the hearing aid in the ear in a position that does not obstruct the outer ear or the ear canal.
-
19. The method of claim 18, wherein the placing of the hearing aid allows natural sound transmissions from an external source through the outer ear and ear canal to be amplified by the outer ear and ear canal to the hearing aid that is inserted at least partially through the tympanic membrane.
-
20. The method of claim 12, further comprising allowing the receipt of transmissions external to the ear through a receiver coupled to the hearing aid.
-
21. The method of claim 12, further comprising allowing the receipt of transmissions through a receiver coupled to the hearing aid from a second hearing aid in an opposite ear.
-
22. An apparatus for enhancing hearing, comprising:
-
a) an outer shell comprising at least two flanges;
b) a microphone;
c) an amplifier; and
d) a speaker;
the microphone, the amplifier and the speaker being coupled to the outer shell and electrically coupled to each other. - View Dependent Claims (23)
