Abstract
Delivering stimulation includes delivering temporal patterns of stimulation pulses to respective transducers of an array of transducers, wherein the delivery of the pattern to a particular transducer of the array is different from at least some of the deliveries of the patterns to the other transducers of the array at least according to a time delay. The patterns delivered may include regular temporal patterns each having a respective constant inter-pulse interval. The constant inter-pulse intervals may be about the same. The patterns may be staggered. The transducers may deliver electrical, optical, acoustic, thermal or magnetic stimulation.
Claims22
A system for delivering electrical pulse stimulation, the system comprising:
- a control device configured to provide programming of intermittent, temporal pulse patterns;
- and
- a stimulation device comprising a control module, multiple electrodes in an array in electrical communication with the control module, and an input device intermittent communication configured to communicate with the control device to receive the programming, the stimulation device configured to deliver respective asynchronous temporal patterns of electrical stimulation pulses to the multiple electrodes according to the programming,
- wherein each respective asynchronous temporal pattern of electrical stimulation pulses activates a different sub-population of targeted neurological tissue of a subject, and
- wherein the control module is configured to deliver the asynchronous temporal patterns by offsetting delivery of some pulse patterns relative to other pulse patterns.
A method of delivering electrical stimulation comprising:
- delivering asynchronous temporal patterns of electrical stimulation pulses to respective electrodes of an array of electrodes or respective transducers of an array of transducers,
- wherein delivering the asynchronous temporal patterns includes offsetting delivery of some pulse patterns relative to other pulse patterns, and
- wherein each respective asynchronous temporal pattern of electrical stimulation pulses activates a different sub-population of targeted neurological tissue of a subject.
A remote control device configured to provide programming of intermittent asynchronous temporal pulse patterns to a stimulation device that comprises an array of electrodes and delivers temporal patterns of electrical stimulation pulses to the electrodes according to the programming, wherein the stimulation device is configured to deliver the asynchronous temporal patterns by offsetting delivery of some pulse patterns relative to other pulse patterns, and wherein each respective asynchronous temporal pattern of electrical stimulation pulses activates a different sub-population of targeted neurological tissue of a subject.
