Abstract
Miniature implanted muscle, nerve and brain stimulators are powered by inductive coupling to a large coil which is preferably placed under the bed. Preferably the operation of the system is controlled by a programmable timer to operate when the user is resting or asleep. Two coils operated at two different positions can be used simultaneously to avoid spots with no signal. When the system is used to reduce angina pains, the pulsation is synchronized to the cardiac rhythm by picking up the electro-cardiac signals.
