Implantable neurostimulators having reduced pocket stimulation
First Claim
1. 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 a single electrical pulse from the neurostimulator, thereby stimulating a target tissue site remote from the tissue pocket; and
independently returning a plurality of electrical pulses respectively to the electrodes in a temporally interleaved fashion, wherein each electrical pulse returned to the respective electrodes has a shorter duration than the single electrical pulse.

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.
