Dosing limitation for an implantable medical device
First Claim
1. A method of electrical signal therapy provided by an implantable medical device (IMD) to a cranial nerve of a patient, comprising:
- specifying an electrical signal parameter threshold;
wherein said electrical signal parameter is specific to the electrical signal therapy; and
wherein said threshold is selected from the group consisting of a maximum number of patient-initiated signals to provide a therapeutic electrical signal per a time period, a maximum dose of therapeutic electrical signals per a time period, a maximum duration of the therapeutic electrical signals per a time period, a maximum rate of change of the number of patient-initiated signals to provide a therapeutic electrical signal per a time period, a maximum rate of change of the dose of the therapeutic electrical signal per a time period, and a maximum rate of change of the duration of the electrical signal therapy per a time period,receiving an input from said patient to enter an alternative mode of electrical signal therapy;
wherein said alternative mode of electrical signal therapy comprises altering the electrical signal parameter of the electrical signal therapy and wherein said input from said patient to enter said alternative mode of electrical signal therapy also prompts a temporary interruption from a normal stimulation mode of electrical signal therapy provided by the IMD;
determining whether to implement said alternative mode of electrical signal therapy based on said electrical signal parameter threshold,and performing said alternative mode of electrical signal therapy when said electrical signal parameter of said alternative mode of electrical signal therapy is below said threshold, andnot performing said alternative mode of electrical signal therapy when said electrical signal parameter of said alternative mode of electrical signal therapy is above said threshold, to inhibit the patient initiated electrical signal therapy provided by the IMD to the cranial nerve of the patient.

Abstract
A method for limiting patient-initiated electrical signal therapy to a cranial nerve of a patient is provided. An electrical signal therapy limit is selected from the group consisting of; a maximum number of patient-initiated signals, a maximum dose of electrical signals, a maximum duration of electrical signal, a maximum rate of change of the number of patient-initiated signals, a maximum rate of change of the dose of electrical signals, and a maximum rate of change of the duration of the electrical signals all per unit of time. If the electrical signal therapy limit is exceeded a therapy is delivered to the cranial nerve selected from the group consisting of; providing therapy, providing reduced therapy, providing enhanced therapy, inhibiting therapy, providing background therapy, and inhibiting background therapy.

4. A method for limiting patient-initiated electrical signal therapy provided by an implantable medical device (IMD) to a cranial nerve of a patient, comprising:
-
specifying at least one electrical signal therapy limit selected from the group consisting of a maximum number of patient-initiated signals to provide a therapeutic electrical signal per a time period, a maximum dose of the therapeutic electrical signal per a time period, a maximum duration of the therapeutic electrical signal per a time period, a maximum rate of change of the number of patient-initiated signals to provide a therapeutic electrical signal per a time period, a maximum rate of change of the dose of the therapeutic electrical signal per a time period, and a maximum rate of change of the duration of the electrical signal therapy per a time period; receiving a patient-initiated signal to begin a patient-initiated therapeutic electrical signal, wherein the patient-initiated therapeutic signal prompts a temporary interruption from a normal stimulation mode of electrical signal therapy; determining whether or not said patient-initiated electrical signal therapy limit will be exceeded if said receiving the patient-initiated signal to begin the patient-initiated electrical signal therapy is implemented; performing an action when said limit is not exceeded, said action selected from the group consisting of providing an electrical signal therapy to said cranial nerve, providing a reduced electrical signal therapy to said cranial nerve, providing an enhanced electrical signal therapy to said cranial nerve and providing a background electrical signal to said cranial nerve; and performing a different action when said limit is exceeded, said different action selected from the group consisting of inhibiting said patient-initiated electrical signal therapy to said cranial nerve. - View Dependent Claims (5, 6, 7, 8, 9, 10)
