Methods and systems for fitting a cochlear implant to a patient
First Claim
1. A method of fitting a cochlear implant system to a patient, said method comprising:
- establishing an implant fitting line having a slope and a horizontal position, said fitting line representing a mapping relationship between a plurality of audio frequencies and a plurality of stimulation sites within a cochlea of said patient;
displaying a graphical representation of said fitting line as part of a graphical user interface;
presenting a first audio signal to said patient, said first audio signal comprising at least one of said audio frequencies;
applying a stimulus current to one or more stimulation sites corresponding to said at least one of said audio frequencies within said first audio signal in accordance with said mapping relationship defined by said fitting line; and
adjusting said slope of said fitting line via said graphical user interface based on a response of said patient to said stimulus current in order to adjust said mapping relationship between said plurality of audio frequencies and said plurality of stimulation sites.

Abstract
An exemplary method of fitting a coeblear implant system to a patient includes establishing an implant fitting line having a slope and a position. The implant fitting line represents a relationship between a number of stimulation sites within a cochlea of the patient and a number of corresponding audio frequencies. That is, the implant fitting line defines which locations along the length of the cochlea, when stimulated, are perceived by the patient as specific tones or frequencies. The method further includes presenting a first audio signal having a number of audio frequencies to the patient and applying a stimulus current to one or more stimulation sites corresponding to the number of audio frequencies of the first audio signal. The method further includes adjusting the slope of the fitting line based on a response of the patient to the stimulus current.

17. A system for fitting a cochlear implant to a patient, said system comprising:
-
an implantable cochlear stimulator configured to generate a stimulus current; and a fitting device conununicatively coupled to said iniplantable cochlear stimulator and configured to display a graphical representation of an implant fitting line as part of a graphical user interface, said implant fitting line having a slope and a horizontal position and representing a mapping relationship between a plurality of audio frequencies and a plurality of stimulation sites within a cochlea of said patient; wherein said implantable cochlear stimulator is further configured to apply said stimulus current to one or more of said stimulation sites that correspond to one or more audio frequencies within a first audio signal in accordance with said mapping relationship defined by said fitting line; and wherein said fitting device is further configured to facilitate adjustment of said slope of said fitting line via said graphical user interface based on a response of said patient to said stimulus current. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A system for fitting a cochlear implant system to a patient, said system comprising:
-
means for establishing an implant fitting line having a slope and a horizontal position, said fitting line representing a mapping relationship between a plurality of audio frequencies and a plurality of stimulation sites within a cochlea of said patient; means for dispalying a graphical representation of said fitting line as part of a graphical user interface; means for presenting a first audio signal to said patient, said first audio signal comprising at least one of said audio frequencies; means for applying a stimulus current to one or more stimulation sites corresponding to said at least one of said audio frequencies within said first audio signal in accordance with said mapping relationship defined by said fitting line; and means for adjusting said slope of said fitting line via said graphical user interface based on a response of said patient to said stimulus current in order to adjust said mapping relationship between said plurality of audio frequencies and said plurality of stimulation sites. - View Dependent Claims (29, 30, 31)
