Abstract

A cochlear implant system comprising a first unit adapted to be worn on or in one ear of an implantee. The first unit has a case housing componentry including a microphone, and a speech processor means. A second unit or accessory is adapted to be worn on or in the other ear of the implantee. The second unit or accessory has a case housing a second power source. An electrical conduction means for transmitting power from the second power source to the componentry of the first unit extends between the first and second units. Such a conduction means can extend around the back of the head of the implantee.

the second speech processor; and

the microphone, wherein the microphone is configured to detect sounds and to provide acoustic data signals representative of the detected sounds to the second speech processor, the second speech processor is configured to generate coded data signals based on the acoustic data signals, and the transmission system is configured to provide the coded date signals from the accessory to the external component.

4. The accessory of claim 3, wherein the transmission system comprises first and second electrical leads and a cable housing the first and second electrical leads, and wherein the first electrical lead is configured to provide power from the power source to the external component and the second electrical lead is configured to provide the coded data signals from the second speech processor to the external component.

5. The accessory of claim 1, wherein the transmission system comprises a wireless transmission system, and wherein the wireless transmission system is configured to provide power from the power source to the external component.

6. The accessory of claim 1, wherein the accessory further comprises:

the radio receiver, wherein the radio receiver is configured to detect radio frequency (RF) signals and output data signals based on the detected signals, and wherein the transmission system is configured to provide the data signals from the accessory to the external component.

7. The accessory of claim 1, wherein the accessory further comprises:

the telecoil, wherein the telecoil is configured to detect one or more of magnetic signals and signals transmitted via a magnetic field and output data signals based on the detected signals, and wherein the transmission system is configured to provide the data signals from the accessory to the external component.

8. A cochlear implant system comprising:

a first unit, configured to be worn on or in the ear canal of an implantee'"'"'s first ear, and comprising a first speech processor;

a second unit configured to be worn on or in an ear canal of the implantee'"'"'s second ear; and

a transmission system configured to transmit one or more of power and data between the first and second units.

9. The cochlear implant system of claim 8, wherein the second unit comprises:

a power source, wherein the transmission system is configured to transmit power from the power source to the first unit.

10. The cochlear implant system of claim 9, wherein the second unit further comprises:

a microphone; and

a second speech processor, wherein the microphone is configured to detect sounds and provide acoustic data signals representative of the detected sounds to the second speech processor, the second speech processor is configured to generate coded data signals based on the acoustic data signals, and the transmission system is configured to provide the coded data signals from the second unit to the first unit.

11. The cochlear implant system of claim 10, wherein the transmission system comprises:

a first electrical lead configured to transmit power from the power source to the first unit;

a second electrical lead configured to transmit the coded data signals from the second speech processor to the first unit; and

a cable housing the first and second electrical leads.

12. The cochlear implant system of claim 8, wherein the transmission system comprises:

a wireless transmission system.

13. The cochlear implant system of claim 12, wherein the wireless transmission system comprises:

a radio frequency (RF) link between the first and second units.

14. The cochlear implant system of claim 8, wherein the second unit comprises:

an antenna; and

a radio receiver electrically connected to the antenna, wherein the antenna and radio receiver are configured to detect radio frequency (RF) signals, the radio receiver is configured to generate data signals representative of the detected RF signals, and the transmission system is configured to provide the data signals from the second unit to the first unit.

15. The cochlear implant system of claim 8, wherein the second unit comprises:

a telecoil system configured to detect one or more of magnetic signals and signals transmitted via a magnetic field, and to generate data signals representative of the detected signals, wherein the transmission system is configured to provide the data signals from the second unit to the first unit.

16. A method of operating a cochlear implant system, the cochlear implant system comprising a first unit having a speech processor, a second unit, a transmission system, and an implanted component, wherein the first unit is configured to be worn on or in the ear canal of an implantee'"'"'s first ear and the second unit is configured to be worn on or in the ear canal of the implantee'"'"'s second ear, the method comprising:

transmitting, via the transmission system, one or more of power and data between the first and second units; and

transmitting one or more of power and data from the first unit to the implanted component.

17. The method of claim 16, wherein the second unit comprises a power source, and wherein transmitting, via the transmission system, one or more of power and data between the first and second units comprises:
