Abstract

Hearing assistance apparatus, systems and methods that involve the use of distributed power without the use of a headpiece.

Claims

1. A hearing assistance system, comprising:

an implantable cochlear stimulator including a battery, an electrode array, a stimulation data receiver apparatus, and a stimulation processor operably connected to the stimulation data receiver apparatus and to the electrode array;

a hearing assistance device including a battery, sound processor circuitry that converts electrical signals from a microphone into stimulation data, and a data communication apparatus configured to wirelessly transmit the stimulation data; and

a retransmission apparatus, including a data communication apparatus, that wirelessly receives the stimulation data and wirelessly transmits the stimulation data to the implantable cochlear stimulator;

wherein the system does not include a headpiece.

2. A hearing assistance system as claimed in claim 1, wherein the implantable cochlear stimulator does not include sound processor circuitry.

3. A hearing assistance system as claimed in claim 1, wherein the hearing assistance device comprises a behind-the-ear hearing assistance device.

4. A hearing assistance system as claimed in claim 1, wherein the hearing assistance device includes the microphone.

5. A hearing assistance system as claimed in claim 1, wherein the data communication apparatus of the hearing assistance device is configured to wirelessly transmit the stimulation data at a first frequency and the data communication apparatus of the retransmission apparatus is configured to wirelessly transmit the stimulation data at a second frequency that is different than the first frequency.

6. A hearing assistance system as claimed in claim 1, wherein the retransmission apparatus includes a battery.

7. A hearing assistance system as claimed in claim 1, wherein the retransmission apparatus includes a housing and an elongate loop-shaped antenna located outside the housing.

8. A hearing assistance system as claimed in claim 1, wherein the hearing assistance device does not supply power to the implantable cochlear stimulator.

9. A hearing assistance system as claimed in claim 1, wherein the data communication apparatus of the hearing assistance device comprises a transmitter and an antenna.

10. A hearing assistance system as claimed in claim 1, wherein the implantable cochlear stimulator does not include a magnet.

11. A hearing assistance system, comprising:

an implantable cochlear stimulator including a battery, an electrode array, a stimulation data receiver apparatus, and a stimulation processor operably connected to the stimulation data receiver apparatus and to the electrode array;

a hearing assistance device, including a battery, a microphone that converts sound pressure waves into electrical signals, and data communication apparatus that wirelessly transmits the electrical signals; and

a retransmission apparatus, which is not configured to be mounted on the user'"'"'s head, including a data communication apparatus and sound processor circuitry, that wirelessly receives electrical signals from the hearing assistance device, converts the electrical signals from the microphone into stimulation data, and wirelessly transmits the stimulation data to the implantable cochlear stimulator.

12. A hearing assistance system as claimed in claim 11, wherein the hearing assistance device comprises a CIC hearing assistance device.

13. A hearing assistance system as claimed in claim 11, wherein the data communication apparatus of the hearing assistance device comprises a transmitter and an antenna.

14. A hearing assistance system as claimed in claim 11, wherein the hearing assistance device does not include sound processor circuitry.

15. A hearing assistance system as claimed in claim 11, wherein the hearing assistance device does not supply power to the implantable cochlear stimulator.

16. A hearing assistance system as claimed in claim 11, wherein the data communication apparatus of the hearing assistance device is configured to wirelessly transmit the electrical signals at a first frequency and the data communication apparatus of the retransmission apparatus is configured to wirelessly transmit the stimulation data at a second frequency that is different than the first frequency.

17. A hearing assistance system as claimed in claim 11, wherein the retransmission apparatus includes a housing and an elongate loop-shaped antenna located outside the housing.

18. A hearing assistance system as claimed in claim 11, wherein the implantable cochlear stimulator does not include a magnet.

19. A hearing assistance system, comprising:

an implantable cochlear stimulator including a battery, an electrode array, a stimulation data receiver apparatus, and a stimulation processor operably connected to the stimulation data receiver apparatus and to the electrode array, and not including sound processor circuitry;

a hearing assistance device, including a battery, a microphone that converts sound pressure waves into electrical signals, and data communication apparatus that wirelessly transmits the electrical signals; and

a retransmission apparatus, including a data communication apparatus and sound processor circuitry, that wirelessly receives electrical signals from the hearing assistance device, converts the electrical signals from the microphone into stimulation data, and wirelessly transmits the stimulation data to the implantable cochlear stimulator.
