Abstract
A method and apparatus are provided for altering a function of tissue in a patient. An electromagnetic signal generated by a signal generator is applied to the tissue to be altered through an electrode. The electromagnetic signal has at least one frequency component above the physiologic stimulation frequency range at an intensity sufficient to produce an alteration of the tissue and a waveform that inhibits temperature elevation to the lethal temperature range of the tissue. Both externally coupled and fully implanted electrode and signal generator systems can be used at tissue sites in various parts of the body.
