Information processing and storage in a cochlear stimulation system
First Claim
1. A method of performing neurostimulation by a cochlear stimulation system, the method comprising:
- transferring an item of patient specific information from a non-implantable speech processor of a cochlear stimulation system to an implantable neurostimulator portion of the cochlear stimulation system;
storing the item of patient specific information in a non-volatile memory of the implantable neurostimulator portion of the cochlear stimulation system;
initializing the implantable neurostimulator portion of the cochlear stimulation system using the item of patient specific information stored in the non-volatile memory; and
neurostimulating a cochlear nerve with an electrical current configured from the item of patient specific information stored in the non-volatile memory,wherein the item of patient specific information comprises a personalized configuration setting of stimulation parameters for use by the implantable neurostimulator portion.

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.

11. A cochlear implant system, comprising:
-
an external portion; an implantable portion, communicatively coupled to the external portion, comprising; an electrode array; a non-volatile storage area; stimulation circuitry, coupled to the electrode array and the non-volatile storage area, configured for bidirectional communication with the external portion, wherein the external portion is wearable on a head of a patient; wherein the stimulation circuitry is configured to receive patient specific information from the external portion; store the patient specific information in the non-volatile storage area; initialize the stimulation circuitry using the stored patient specific information without receiving information from the external portion; generate an electrical current by the stimulation circuitry based on the item of patient specific information; and neurostimulate a cochlear nerve of the patient with the electrical current. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
