Device for deep electrical and optical brain stimulation

A deep brain stimulation device comprising:

• a stimulation probe comprising:
• a longilineal body having a central channel void of material running therethrough, extending between a distal portion and a proximal end of the probe, the central channel being open at said proximal end and the distal portion of the body being capable of transmitting a predetermined wavelength;
• electrodes affixed to an outer surface of the body in the distal portion of the probe for electric brain stimulation;
• and
• electrical terminals affixed to an outer surface of the body in the proximal end of the probe and connected to the electrodes for their electric power supply;
• an electrical housing comprising a channel having electrical terminals housed therein, said channel being open at one of its ends to receive the proximal portion of the probe to place into contact the electrical terminals of the probe and the electrical terminals of the housing;
• and
• an electrical extension lead affixed to the electrical housing and connected to the electrical terminals of the housing,
• wherein the channel of the electrical housing is open at the other one of its ends;
• and
• wherein the device further comprises:
• a waveguide capable of guiding the predetermined wavelength, housed at least partly in the central channel of the probe body, and extending all the way to the distal portion of the probe for the illumination of the brain therethrough;
• and
• a transmitter housing capable of being connected to the proximal end of the waveguide for the injection into it of the predetermined wavelength.
