Medical stimulation and/or monitoring device interacting with the body of a patient based upon selectable parameter set

Claim 1

A medical device comprising: a housing having a size adapted for implantation in the body of a patient; means adapted for interacting with the body of said patient with respect to a physiological function of the patient; control means in said housing and electrically connected to said means adapted for interacting, for defining the interaction of said means adapted for interacting on the basis of a parameter set; a memory in said housing containing a plurality of different parameter sets each parameter set comprising values of a plurality of individual parameters matched to a specific set of physiological conditions of said patient with each set of conditions requiring a different interaction with said patient by said means for interacting, and each of said parameter sets being stored as a set at a specific Address of said memory; said control means including means for fetching one of said parameter sets at a time for use by said control means; and switch means connected to said control means for enabling only the address of a parameter set matched to current conditions, said switch means including pacemaker wearer-operated means for selecting an address which is to be enabled, said pacemaker wearer-operated means being an external unit and further including means for telemetrically communicating between said control means in said housing and said external unit.
