Abstract
An implantable medical system includes a light delivery module comprising a light source that generates light and a controller that controls the output of the light source, a lead with a plurality of electrodes, the lead extending from a proximal end to a distal end, wherein the lead further comprises an optical light guide configured to deliver the light from the light source, and the controller is configured to deliver voltage across two or more of the electrodes to steer a distal end of the optical light guide, to provide electrical stimulation or sense/record electrical signals.
Claims21
An implantable medical system comprising:
- a light delivery module comprising a light source that generates light and a controller that controls an output of the light source;
- and
- a lead with a plurality of electrodes, the lead extending from a proximal end to a distal end,
- wherein the lead further comprises an optical light guide configured to deliver the light from the light source, wherein the optical light guide comprises a property of being affected by a magnetic field, and
- the controller is configured to deliver voltage across two or more of the electrodes to steer a distal end of the optical light guide.
A method comprising:
- controlling delivery of voltage across electrodes of a lead to steer a distal end of an optical light guide of the lead, wherein the optical light guide comprises a property of being affected by a magnetic field;
- and
- transmitting light from a light source of an implantable medical system to a patient via the optical light guide of the lead.
