Neural stimulation and optical monitoring systems and methods
First Claim
1. An apparatus for treating a neural condition, comprising:
- a signal delivery device configured to be implanted into a patient proximate to a skull of the patient and positioned to apply electromagnetic signals to one or more target neural sites within the patient;
an implantable optical monitoring assembly configured to monitor optical properties at one or more optical monitoring sites within the patient, wherein the signal delivery device and optical monitoring assembly are both carried by an implantable, generally planar support member;
a controller configured to be implanted into the patient, the controller being operatively coupled to the signal delivery device and the optical monitoring assembly and programmed to control both the signal delivery device and the optical monitoring assembly, and wherein the controller includes a power source to power both the signal delivery device and the optical monitoring assembly;
the optical monitoring assembly including one or more optical emission elements carried by the support member, and one or more optical detection elements carried by the support member, wherein the one or more optical emission elements and the one or more optical detection elements are arranged relative to each other to detect optical signals from the one or more optical monitoring sites; and
wherein the one or more optical detection elements and the one or more optical emission elements are separated from each other by approximately 0.5 cm to approximately 5.0 cm and further wherein the one or more optical detection elements are arranged in a phased optical array.
