Abstract

A compartmentalized fitting system that may be used by a recipient to determine device parameters, such as threshold and/or maximum comfort levels, for a stimulating medical device is provided. The compartmentalized fitting system segregates the fitting procedure into separate sessions. For example, in an embodiment, the fitting system provides a clinician driven setup session whereby a clinician may specify parameters that are to be used in fitting the medical device. After which, the fitting system may enter a recipient driven fitting session that is used to determine one or device parameters for the stimulating medical device. Once determined, the fitting system passes control to a clinician driven approval session whereby the clinician can approve the determined set of device parameters; and, if approved store the determined device parameters. This storage may comprise loading the determined device parameters onto the stimulating medical device for subsequent use by the device.
