Multi-electrode neurostimulation device

摘要

A neurostimulation device is provided comprising an input, a neurostimulation probe, a stimulation unit and a distribution calculation module. At the input stimulation data is received comprising information relating to a stimulation preferability and an orientation of at least one fiber bundle. The neurostimulation probe comprises an array of stimulation electrodes which are coupled to the stimulation unit. The stimulation unit, in accordance with a specified current distribution, provides currents to the respective stimulation electrodes for generating an electric field gradient. The distribution calculation module is coupled to the input and the stimulation unit for based on the stimulation data determining a preferred position and orientation for the electric field gradient, and based on the preferred position and orientation for the electric field gradient, calculating the specified current distribution.
