Abstract
Neurostimulators and methods of using neurostimulators are provided. The neurostimulator is implanted within a tissue pocket of a patient, and electrical energy is conveyed from the neurostimulator to stimulate a target tissue site remote from the tissue pocket. The neurostimulator has a case with which one or more electrodes are associated. The electrical energy is returned to the electrode(s) in a manner that prevents, or at least reduces, pocket stimulation that may otherwise occur due to the return of electrical energy to the case of the neurostimulator.
Claims29
A method of providing therapy using a neurostimulator implanted within a tissue pocket of a patient, the neurostimulator having a case and a plurality of electrodes associated with the case, comprising:
- conveying electrical energy from the neurostimulator, thereby stimulating a target tissue site remote from the tissue pocket;
- and
- independently returning the electrical energy to the electrodes.
The method of claim 9, wherein the electrodes form at least a portion of the case.
A neurostimulator, comprising:
- a case;
- a plurality of electrodes associated with the case;
- one or more connectors configured for being coupled to one or more stimulation leads;
- stimulation circuitry contained within the case, the stimulation circuitry configured for conveying electrical energy to the one or more stimulation leads, and independently returning the electrical energy to the electrodes.
The neurostimulator of claim 23, wherein the plurality of electrodes comprises at least three electrodes, and the stimulation circuitry is configured for serially returning the electrical energy to the at least three electrodes.
