1. A system for fitting an implantable cochlear stimulator to a patient, said system comprising:
- an interface unit configured todisplay a graphical representation of a substantially linear 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; and
facilitate adjustment via said graphical user interface of said slope of said fitting line to substantially match a slope of an intrinsic line that represents a relationship between locations within the cochlea and a plurality of audio frequencies as actually perceived by the patient, said adjustment based on a response of said patient to a stimulus current applied by said cochlear stimulator to a subset of said stimulation sites in accordance with said mapping relationship defined by said fitting line.

Abstract
Systems for fitting an implantable cochlear stimulator to a patient include an interface unit configured to display a graphical representation of an implant fitting line as part of a graphical user interface. The implant fitting line has a slope and a horizontal position and represents a mapping relationship between a plurality of audio frequencies and a plurality of stimulation sites within a cochlea of the patient. The interface unit is further configured to facilitate adjustment of the slope and/or horizontal position of the fitting line.
