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.
