Deep brain stimulation apparatus, and associated methods
First Claim
1. An apparatus for providing electrical stimulation to the brain of a patient, comprising:
- one or more probes for being implanted in said brain and for providing electrical pulses to said brain;
an implantable device for being implanted subcutaneously in said patient'"'"'s head, said implantable device having;
(i) control circuitry electrically connected to said one or more probes, said control circuitry being adapted to generate said electrical pulses and provide said electrical pulses to said one or more probes, and (ii) power circuitry electrically connected to said control circuitry, said power circuitry providing a DC power signal to said control circuitry; and
a power supply separate from said implantable device and external to said patient'"'"'s body, said power supply providing power to said implantable device through a near-field technique between said power supply and said power circuitry when said power circuitry is in proximity with said power supply.

Abstract
Various methods and apparatus for providing deep brain stimulation for the treatment of diseases such as Parkinson'"'"'s Disease that do not require an onboard power supply that is implanted in the patient'"'"'s body. Power may be supplied from outside of the body by, for example, near-field inductive coupling with an external power supply provided in, for example, a headgear worn by the patient. Power may also be supplied by providing an antenna for harvesting ambient energy, such as ambient RF energy, and converting it into DC power. In addition, the methods and apparatus provide for remote, wireless programming of the parameters that specify the nature of electrical pulses provided to the brain via probes implanted in the brain.
