Information processing and storage in a cochlear stimulation system
First Claim
1. A method for operating a cochlear stimulation system worn by a patient comprising an external portion and an implantable internal portion, the method comprising:
- storing non-patient specific information in a non-volatile memory in the external portion;
storing patient specific information in a non-volatile memory in the internal portion;
processing sensed acoustic signals at the external portion using only non-patient specific information to produce a data signal comprising amplitude data that has been processed with a speech processing algorithm, wherein the speech processing algorithm includes filtering and noise cancelling;
wirelessly transmitting the data signal from the external portion to the internal portion;
processing the data signal at the internal portion using patient specific information; and
generating stimulation waveforms at the internal portion based on the processed data signal.

Abstract
Information can be stored in a cochlear stimulation system by determining an item of patient specific information, transferring the item of patient specific information to an implantable portion of the cochlear stimulation system, and permanently storing the item of patient specific information in the implantable portion of the cochlear stimulation system. The item of patient specific information can comprise a parameter for use in generating a stimulation current. The implantable portion of the cochlear stimulation system also can be configured to permanently store one or more items of patient specific information in an alterable fashion. Further, an item of patient specific information can be retrieved from the implantable portion of the cochlear stimulation system. Additionally, an item of non-patient specific information for use in processing a received acoustic signal can be determined and permanently stored in an external portion of the cochlear stimulation system.
