SYSTEMS AND METHODS FOR AUTOMATICALLY OPTIMIZING STIMULUS PARAMETERS AND ELECTRODE CONFIGURATIONS FOR NEUROSTIMULATORS
First Claim
1. A neuro-stimulation system, comprising:
- an electrode array having an implantable support member configured to be implanted into a patient and a plurality of therapy electrodes carried by the support member;
a pulse system operatively coupled to the therapy electrodes, the pulse system delivering a stimulus to the therapy electrodes; and
a controller operatively coupled to the pulse system, the controller including a computer operable medium containing instructions that generate command signals that define the stimulus delivered by the pulse system and determine a desired configuration for the therapy electrodes and/or a desired stimulus to be delivered to the therapy electrodes based upon feedback input to the controller.

Abstract
Test procedures for determining a neural stimulation threshold of a patient. In one embodiment, the procedure includes applying a test stimulation signal to the patient and monitoring the patient for a response to the test stimulation signal. The procedure can further include determining a first neural stimulation threshold and calculating a second neural stimulation threshold. The first neural stimulation threshold corresponds to the lowest intensity test stimulation signal that evokes a patient response. The second neural stimulation threshold corresponds to a treatment stimulation signal directed toward affecting a neural activity within the patient.

15. In a computer, a method of automatically determining a favorable neuro-stimulation program for a patient, comprising:
-
applying an electrical stimulus having a plurality of stimulus parameters to a selected configuration of the therapy electrodes that have been installed at a target therapy site of a patient; sensing a response to the applied electrical stimulus at a sensing device that has been installed at a sense location of the patient; determining whether the response is within a desired range or an improvement over a previous sensed response from a different electrical stimulus and/or a different configuration of therapy electrodes; selecting an alternate configuration of therapy electrodes and/or an alternate electrical stimulus; repeating the applying, sensing, determining and selecting procedures using the alternate configuration of therapy electrodes and/or the alternate electrical stimulus; and choosing a configuration of therapy electrodes and/or an electrical stimulus corresponding to a sensed response that is within a desired range and/or provides a better result compared to other sensed responses. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
