Neuromodulation system and method for automatically adjusting stimulation parameters to optimize power consumption
First Claim
1. A method, comprising instructing a neuromodulation device to:
- deliver electrical energy for a therapy including deliver a therapeutically-effective amount of energy and then automatically deliver a series of decreasing amounts of energy;
receive, at a time when the electrical energy is delivered at a current one in the series of decreasing amounts of energy, a user input signal indicative that the therapy is no longer effective when the electrical energy is delivered at the current one in the series of decreasing amounts of energy, wherein the automatically deliver the series of decreasing amounts of energy includes automatically decrement energy within the series after expiration of a predetermined time period only when the user input signal is not received before the expiration of the predetermined time duration; and
in response to the received user input signal, deliver the electrical energy for the therapy at one of the series of decreasing amount of energy that immediately precedes the current amount of energy.

Abstract
An electrical neuromodulation system configured for minimizing energy consumption of a neuromodulation device includes an external control device configured for receiving input from a user, the neuromodulation device in communication with the external control device, and control/processing circuitry. The control/processing circuitry is configured for automatically (a) adjusting a modulation parameter value (e.g., by a step size) to create a currently adjusted modulation parameter value that decreases the energy consumption of the neuromodulation device, (b) instructing the neuromodulation device to deliver electrical energy to at least one electrode in accordance with the currently adjusted modulation parameter value, (c) determining whether a manual parameter adjustment was made by the user in response to step (b), and (d) if the manual parameter adjustment was not made, deeming the currently adjusted modulation parameter value as a previously adjusted modulation parameter value and repeating steps (a)-(d).
