Benefits of technology

[0007]The present invention is directed to a modulated high frequency system for use with a signal applicator such as an electrode, conductive plate, or structure, which is applied to a patient's body to modify its neural function. The present system advantageously relieves pain or modifies a patient's neural system without average heat

Problems solved by technology

Tissue generally dies when heated to about 45° C. to 50° C., which causes the patient to suffer severe, if not, unbearable pain.
Use of local or general anesthetic exposes a patient to undesired risks, and the destructive nature of and unpleasant side effects of the radiofrequency (RF) heat lesions are limitations of this technique, which is well known.
Chronologically or permanently impl

Embodiment Construction

[0029]Referring to FIG. 1, an illustration of the system and the method in accordance with the present invention in shown by a block diagram and schematic elements. An electrode with an uninsulated conductive surface 1 (for example, a conductive tip end) is shown in the proximity of a region of neural tissue NT illustrated schematically within a dashed boundary. The electrode has an insulated shaft 2 (shown by the cross hatched lines) and connection or hub portion 3, inside of which there may be electric connections to the surface 1. A connector 10 electronically connects to the surface 1 through the electrode shaft 2 and to electronic supply units 4 and 5 (which are illustrated outside the body, but which alternatively, may be miniaturized and implanted inside the body). The electronic supply unit 5 represented in block form is a signal generator having a signal output, which may be voltage, current, or power. The electronic supply unit 4 is a modulator to modulate (for example the...

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.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to technological advances in the medical field and systems and procedures for prolonging and improving human life. More particularly, this invention relates to a method and system for altering or modifying neural tissue in a human body by using a modulated radiofrequency generator coupled to a signal applicator system that is strategically located in tissue near a patient's neural system to relieve pain without heating it to lethal levels.BACKGROUND OF THE INVENTION[0002]In the past, radiofrequency (RF) generators and electrodes have been applied near or in neural tissue, for relieving pain or modifying its function. By way of one example, a lesion generator identified by Model No. RFG-3C RF, available from a company named Radionics, Inc., located in Burlington, Mass., has electrodes, which may be placed near a desired neural tissue area. The desired neural tissue area is heated by radiofrequency (RF) resistive power dissi...
