Network interface module for bilateral cochlear implant systems
View Patent ↗A network interface module that forms part of a bilateral cochlear implant system which allows two standalone BTE units to be synchronized both temporally and tonotopically in order to maximize a patients listening experience. The bilateral cochlear network includes a communications interposer adapted to be inserted between the BTE battery and the BTE housing or modified BTE devices.
1. An interposer unit for use with a BTE speech processor and a battery of a cochlear implant system, the interposer unit being adapted to be interposed between the BTE speech processor and the battery, the interposer unit comprising:
a module having a first side adapted to contact the BTE speech processor and a second side adapted to contact the battery when the module is interposed between the BTE speech processor and the battery;
a BTE interface port located on the first side of the module, the BTE interface port having electrical contacts adapted to make electrical connections with electronic circuits within the BTE speech processor when the module in interposed between the BTE speech processor and the battery;
communication means for establishing a communication link between the electrical contacts of the BTE interface port and a device remote from the module; and
power terminals located on the first side of the module and corresponding power terminals located on the second side of the module, the power terminals on the first side of the module being electrically connected to corresponding power terminals on the second side of the module, wherein power connections from the battery pass through the module to the BTE sound processor when the module is interposed between the BTE speech processor and the battery.
2. The interposer unit of claim 1 wherein the communication means comprises a communications port located on one side of the module, the communications port having electrical terminals that are respectively connected to the electrical contacts of the BTE interface port, wherein the communications port is adapted to detachably receive a communications cable connected to the device remote from the module.
3. The interposer unit of claim 1 wherein the communication means comprises a cable hard wired to the module, wherein the cable has wires that connect with the electrical contacts of the BTE interface port, wherein the cable has a distal end adapted to detachably connect with the device remote from the module.
4. The interposer unit of claim 1 wherein the communication means comprises a wireless transceiver housed within the module and connected to the electrical contacts of the BTE interface port.
5. The interposer unit of claim 4 wherein the wireless transceiver is selected from the group comprising Bluetooth, ISM, Medical Band, FIS ITEL, and the like.
6. The interposer unit of claim 1 further including a control module housed within the module, the control module comprising electronic circuitry that is interposed between the electrical contacts of the BTE interface port and the communication means.
7. The interposer unit of claim 6 further including a wireless network interface module coupled to the control module and an antenna coupled to the wireless network interface module.
8. The interposer unit of claim 6 further including a wired network interface module coupled to the control module.
