Parametric fitting of a cochlear implant
First Claim
1. A method of fitting an auditory stimulation system having a plurality of channels to a recipient, the method comprising:
- establishing a first current level profile comprising a first current level setting for each of the plurality of channels;
applying stimulation using the first current level profile;
obtaining a response to the applied stimulation;
based on the obtained response, adjusting more than one of the first current level settings to effectuate a tilt of the first current level profile about a pivot point on the first current level profile and thereby generate a second current level profile; and
applying stimulation using the second current level profile.

Abstract
A method of fitting an auditory stimulation system to a recipient the system having a plurality of channels, and the method including the steps of establishing an initial current level profile representative of a current level setting spanning across at least some of the plurality of channels and adjusting parameters of the initial current level profile in the presence of a stimulation signal. There is further included a programming apparatus adapted to be interfaced with the auditory stimulation system to allow manipulation of threshold (T) and comfort (C) levels of the system. The apparatus includes a graphical display means adapted to display a graphical representation of the current profile of the channel array and means for adjusting a current level setting of the current profile of the array.

2. An apparatus configured to interface with an auditory stimulation system having a plurality of channels, wherein the apparatus is further configured to establish a first current level profile comprising a first current level setting for each of the plurality of channels;
- display a graphical representation of the first current level profile;
instruct the auditory stimulation system to apply stimulation using the first current level profile;
obtain a response to the applied stimulation;
adjust, based on the obtained response, more than one of the first current level settings to effectuate a tilt of the first current level profile about a pivot point on the profile and thereby generate a second current level profile; and
provide the second current level profile to the auditory stimulation system for use in applying stimulation using the second current level profile. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

30. A method of fitting an auditory stimulation system, having a plurality of channels, to a recipient, the method comprising:
-
establishing a first current level profile comprising a current level setting for each of the plurality of channels, wherein establishing the first current level profile comprises; measuring a first threshold for each channel of a first subset of the plurality of channels, wherein the first subset comprises fewer than all of the channels; and determining, from the measured first thresholds, the current level setting for each channel of the plurality of channels; applying stimulation using the first current level profile; obtaining a response to the applied stimulation; and adjusting a plurality of the current level settings by effectuating a tilt of at least a portion of the first current level profile about a pivot point on the at least a portion of the first current level profile based on the obtained response. - View Dependent Claims (31, 32, 33)
