Optical stimulation implant

A medical device, comprising:

• a housing configured to be mounted between a patient's skull and scalp and to receive electrical power via one or more electrical leads from an implantable pulse generator (IPG) implanted in the patient remote from the patient's head;
• a light source contained within the housing configured to be powered by the electrical power received from the IPG;
• and
• a light path attached to and extending from the housing and configured to provide a path for light from the light source to a target neural area, wherein the light path comprises:
• a proximal section configured to traverse a portion of the patient's skull between the skull and scalp,
• an arcuate section configured to penetrate through a hole in the skull, and
• a light pipe configured to penetrate the brain to the target neural area, the light pipe comprising a hollow tubular member having a first end and a second end, wherein the second end comprises a diffuser or lens attached to the hollow tubular member, wherein,
• a first end of the proximal section connects to the housing and a second end of the proximal section connects to a first end of the arcuate section, and wherein
• a second end of the arcuate section connects to the first end of the light pipe, and
• a fiber optic member contained within the proximal section and the arcuate section and terminating in the arcuate section so that the fiber optic member does not extend through the tubular member of the light pipe and configured to allow light from the fiber optic member to traverse the interior of the hollow tubular member to the diffuser or lens.
