METHODS AND SYSTEM FOR BRAIN STIMULATION
First Claim
1. A method for reducing power consumption in an implantable stimulation device having an internal pulse generator (IPG), a power supply adapted for powering the IPG, and at least one electrode operably coupled with the IPG, comprising the steps of:
- a. causing the IPG to generate a train of electrical pulses, wherein the train of electrical pulses comprises a series of pulse sets, each of the plurality of pulse sets having a plurality of pulses time-evenly distributed over a first period of time, T1, any two neighboring pulse sets of the series of pulse sets being separated by a second period of time, T2, and any two neighboring pulses of the plurality of pulses being separated by a third period of time, T3; and
b. delivering the train of electrical pulses to a target of interest of a living subject for stimulation by the at least one electrode placed in the target of interest.

Abstract
A method for stimulating a target of interest of a living subject with reduction of power consumption. In one embodiment, the method includes the steps of delivering a plurality of pulses to the target of interest in a substantially repeating pattern for a first period of time, T1, which is immediately followed by a second period of time, T2, during which no pulses are delivered to the target of interest, wherein the plurality of pulses is delivered such that any two neighboring pulses of the plurality of pulses are occurred in a third period of time, T3; and repeating the delivering step for a predetermined times, where T1 and T2 are in the order of milliseconds, and T1>T3 and T2≧T3.
