Systems, devices, and methods for electrical stimulation using feedback to adjust stimulation parameters
First Claim
1. An electrical stimulation system, comprising:
- at least one sensor configured and arranged to be disposed on or within a body of a patient and to measure at least one biosignal; and
a control module comprising a processor, wherein the control module is configured and arranged to use stimulation parameters to provide electrical stimulation signals to an electrical stimulation lead coupled to the control module for stimulation of patient tissue, wherein the processor is configured and arranged to communicate with the at least one sensor to receive the at least one biosignal and to generate an adjustment to one or more of the stimulation parameters based on at least one of the at least one biosignal, wherein the processor is configured so that when the at least one of the at least one biosignal is indicative of a particular patient activity, the adjustment is a pre-determined adjustment selected for the particular patient activity, wherein the processor is configured so that when the at least one of the at least one biosignal is indicative of a disease or disorder status, the adjustment is followed by the processor waiting for a predetermined latency period after which the processor is configured and arranged to communicate with the at least one sensor to observe a result of the adjustment using the at least one biosignal and determine whether to provide a further adjustment of the stimulation parameters to improve the stimulation.

Abstract
An electrical stimulation system includes a control module that provides electrical stimulation signals to an electrical stimulation lead coupled to the control module for stimulation of patient tissue. The system also includes a sensor to be disposed on or within the body of the patient and to measure a biosignal; and a processor to communicate with the sensor to receive the biosignal and to generate an adjustment to one or more of the stimulation parameters based on the biosignal. The adjustment can be configured and arranged to steer the electrical stimulation signals to stimulate a region of the patient tissue that is different, at least in part, from a region of the patient tissue stimulated prior to the adjustment. Alternatively or additionally, the biosignal is indicative of a particular patient activity and the adjustment is a pre-determined adjustment selected for the particular patient activity.
