Abstract

Abstract Methods and apparatus for regulating ion movement across biological membranes are provided. In one aspect, harmonic frequencies of a fluctuating magnetic field based on cyclotron resonance principles are provided for selectively enhancing transmembrane ion movement. In another aspect, a method and apparatus are provided for simultaneously regulating the transmembrane movement of multiple distinct ionic species using a fluctuating magnetic field. Therapeutic applications of harmonic tuning and multiple tuning are also provided.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 243 words
A method for the therapeutic treatment of a region of tissue in vivo in the presence of at least two distinct ionic species, comprising the steps of: providing a magnetic field generator having means to generate an applied fluctuating magnetic field along an axis; providing a magnetic field sensor and a signal feedback system having a microprocessor which permits adjustment of the parameters of said applied magnetic field along said axis; providing in the path of said axis a region of living tissue in vivo in the presence of at least two distinct ionic species in an ambient static magnetic field; placing said magnetic field generator adjacent said tissue; generating a fluctuating magnetic field along said axis and through said tissue; creating and maintaining a ratio between the frequency of said fluctuating applied magnetic field and the combined strength of said applied magnetic field and said ambient field along said axis, wherein said frequency is within 5% of preselected harmonic frequencies of said at least two distinct ionic species; wherein said harmonic frequencies are odd integer multiples of a fundamental frequency of each ionic species, said fundamental frequency of each of said ionic species being a function of the charge-to-mass ratio of the ionic species and the combined field strength along said axis; and automatically adjusting with said microprocessor said applied magnetic field to maintain said ratio despite changes in said ambient static field due to changes in the direction of said axis.
Claim 2
Independent Claim 243 words
A method for the therapeutic treatment of a region of tissue in vivo in the presence of at least two distinct ionic species, comprising the steps of: providing a magnetic field generator having means to generate an applied fluctuating magnetic field along an axis; providing a magnetic field sensor and a signal feedback system having a microprocessor which permits adjustment of the parameters of said applied magnetic field along said axis; providing in the path of said axis a region of living tissue in vivo in the presence of at least two distinct ionic species in an ambient static magnetic field; placing said magnetic field generator adjacent said tissue; generating a fluctuating magnetic field along said axis and through said tissue; creating and maintaining a ratio between the frequency of said fluctuating applied magnetic field and the combined strength of said applied magnetic field and said ambient field along said axis, wherein said frequency is within 5% of preselected harmonic frequencies of said at least two distinct ionic species; wherein said harmonic frequencies are odd integer multiples of a fundamental frequency of each ionic species, said fundamental frequency of each of said ionic species being a function of the charge-to-mass ratio of the ionic species and the combined field strength along said axis; and automatically adjusting with said microprocessor said applied magnetic field to maintain said ratio despite changes in said ambient static field due to changes in the direction of said axis.
Claim 3
Dependent Claim 20 words
The invention recited in claim 1, wherein said at least two distinct ions are Ca ++ and Mg ++ .
