System for selective spatiotemporal stimulation of the spinal cord
First Claim
1. A system for neuromodulation of a nervous system of a subject, comprising:
- a pulse generator configured to simultaneously deliver independent current or voltage pulses to more than one electrode, wherein the more than one electrodes are configured to cover a portion of the spinal cord to selectively stimulate specific dorsal roots, wherein said pulse generator is operatively connected with the more than one electrodes to provide spatiotemporal stimulation of the portion of the spinal cord, wherein the more than one electrodes are part of a multi-electrode array comprising at least a portion comprising electrodes arranged in a direction transverse relative to the portion of the spinal cord and at least one portion comprising electrodes arranged in a longitudinal direction relative to the portion of the spinal cord.

Abstract
The present disclosure refers to systems for electrical neurostimulation of a spinal cord of a subject in need of nervous system function support. In one example, a system comprises a signal processing device configured to receive signals from the subject and operate signal-processing algorithms to elaborate stimulation parameter settings; one or more multi-electrode arrays suitable to cover a portion of the spinal cord of the subject; and an Implantable Pulse Generator (IPG) configured to receive the stimulation parameter settings from the signal processing device and simultaneously deliver independent current or voltage pulses to the one or more multiple electrode arrays, wherein the independent current or voltage pulses provide multipolar spatiotemporal stimulation of spinal circuits and/or dorsal roots. Such system advantageously enables effective control of nervous system functions in the subject by stimulating the spinal cord, such as the dorsal roots of the spinal cord, with spatiotemporal selectivity.
