Abstract
A method and apparatus for altering a function of neural tissue in a patient. An electromagnetic signal is applied to the neural tissue through an electrode. The electromagnetic signal has a frequency component above the physiological stimulation frequency range and an intensity sufficient to produce an alteration of the neural tissue, the alteration causing the patient to experience a reduction in pain, and a waveform that prevents lethal temperature elevation of the neural tissue during application of the electromagnetic signal to the neural tissue.
Claims9
A system for altering a function of neural tissue in a patient comprising:
- a) signal applicator adapted to apply an electrical signal output to said neural tissue;
- b) a signal generator that generates a electrical signal output having at least one frequency component above a physiologic stimulation frequency range, said at least one frequency component producing an alteration of a function of at least a portion of said neural tissue, and said electrical signal output having a waveform that produces an average power deposition in the neural tissue corresponding to non-lethal average temperature elevation of said at least a portion of said neural tissue when said electrical signal output is applied to said neural tissue through said signal applicator;
- and
- c) a signal coupler that couples said signal generator and said signal applicator.
A system for altering a function of neural tissue in a patient comprising:
- a) an electrode adapted to apply an amplitude modulated electrical signal to the neural tissue of the patient;
- b) a signal generator that generates an amplitude modulated electrical signal having at least one frequency component above a physiological stimulation frequency range, said amplitude modulated electrical signal producing an alteration of a function of the neural tissue while producing an average power deposition in the neural tissue corresponding to non-lethal temperature elevation of said neural tissue when the amplitude modulated electrical signal is applied to the neural tissue through said electrode;
- and
- c) an electrical coupling between said signal generator and said electrode to apply said amplitude modulated electrical signal to said electrode.
A method for altering the function of neural tissue in a patient comprising the steps of:
- a) generating an electrical signal having at least one frequency component above a physiologic stimulation frequency range, said at least one frequency component producing an alteration of at least a portion of said neural tissue, and said electrical signal having a waveform that produces an average power deposition in the neural tissue corresponding to non-lethal average temperature elevation of said at least a portion of said neural tissue when said electrical signal is applied to said neural tissue;
- and
- b) applying said electrical signal to said neural tissue.
A system for altering a function of at least a portion of neural function of tissue in a patient comprising:
- a) a generator that generates an electromagnetic signal having at least one high frequency component above a physiologic stimulation frequency range, said at least one high frequency component have a modulated waveform that produces alteration of the function of said at least a portion of said neural tissue when applied to said tissue through an electromagnetic signal applicator.
