RANDOM PULSED HIGH FREQUENCY THERAPY

摘要

A method and apparatus for modifying a function of tissue can include the application of an electromagnetic signal output to tissue cells. The electromagnetic signal output can have a waveform with bursts of signal output amplitude that produces fields in the tissue during the burst on-time that can modify cell components. The on-time periods are followed by off-time periods of low signal output amplitude which produce lesser modification effects on cell components. The on-time periods have time durations that are non-predetermined and random. The rate of on-time bursts can be regular, and in one example periodic. In one example, the waveform has amplitudes during the on-time periods and durations of on-time periods that causes elevation of the temperature of tissue that exceeds the lethal temperature levels of 45 to 50° C.

主权项

1. An apparatus for altering a function of living tissue comprising:
an electrode; and a signal generator coupled to the electrode to generate a signal output to be applied to the living tissue through the electrode, the signal output having an interrupted waveform having bursts of on-time periods of a high frequency wave signal, the on-time periods having non-predetermined time durations, each of the on-time periods being followed by off-time periods of low signal output relative to the intensity of the preceding on-time period, and the bursts of the on-time periods commencing at a regular rate, such that the application of the signal output to the living tissue for a sufficient treatment time will result in alteration of a function of the living tissue.
