Abstract:
The neural interface system of the preferred embodiments includes an electrode array having a plurality of electrode sites and a carrier that supports the electrode array. The electrode array is coupled to the carrier such that the electrode sites are arranged both circumferentially around the carrier and axially along the carrier. A group of the electrode sites may be simultaneously activated to create an activation pattern. The system of the preferred embodiment is preferably designed for deep brain stimulation, and, more specifically, for deep brain stimulation with fine electrode site positioning, selectivity, tunability, and precise activation patterning. The system of the preferred embodiments, however, may be alternatively used in any suitable environment (such as the spinal cord, peripheral nerve, muscle, or any other suitable anatomical location) and for any suitable reason.
