Abstract

Abstract A treatment of atherosclerosis by the application of external electromagnetic energy capable of the generation of heat and biophysical alterations in intracellular particles and particles within atherosclerotic plaques to induce resolution of the atherosclerotic plaques. This process allows for the selective treatment of the atherosclerotic plaque without damaging the normal blood vessel by the compartmentalized alteration of biophysical properties within the atherosclerotic lesion. The process comprises introducing minute particles into the interior of atherosclerotic plaques and the cells involved in the lesion. These particles being injected intravenously while suspended in an appropriate solution are of a size generally having a diameter of approximately 1 micron or less and one of a material with properties such as ferromagnetic, paramagnetic or diamagnetic so as to be inductively heated when subjected to a high frequency alternating electromagnetic field. Introducing the particles as described the patient is thereafter subjected to an alternating electromagnetic field to inductively heat the particles sufficiently to raise the temperature of the atherosclerotic lesion and destroy the atherosclerotic lesion without harming the normal artery or intima.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 110 words
A process for the treatment of atherosclerosis in living tissue by application of external electromagnetic energy capable of the generation of heat and the alteration of biophysical properties intracellularly and extracellularly to induce resolution of atherosclerotic lesions comprising: intravenously injecting into the patient minute ferromagnetic, paramagnetic or diamagnetic particles capable of being inductively heated and of size less than 1 micron, selectively absorbing said minute particles intracellularly and extracellularly into the atherosclerotic lesion, subjecting the patient to an alternating electromagnetic field to inductively heat and alter the biophysical properties of the minute particles and thereby the atherosclerotic lesions, continuing the inductive heating of said particles to resolve the atherosclerotic lesions.
Claim 2
Dependent Claim 110 words
A process for the treatment of atherosclerosis in living tissue by application of external electromagnetic energy capable of the generation of heat and the alteration of biophysical properties intracellularly and extracellularly to induce resolution of atherosclerotic lesions comprising: intravenously injecting into the patient minute ferromagnetic, paramagnetic or diamagnetic particles capable of being inductively heated and of size less than 1 micron, selectively absorbing said minute particles intracellularly and extracellularly into the atherosclerotic lesion, subjecting the patient to an alternating electromagnetic field to inductively heat and alter the biophysical properties of the minute particles and thereby the atherosclerotic lesions, continuing the inductive heating of said particles to resolve the atherosclerotic lesions.
Claim 3
Dependent Claim 16 words
The process of claim 1 wherein the particles are selected from ferric hydroxide and iron oxide.
Claim 4
Dependent Claim 31 words
The process of claim 1 including providing an atherosclerotic seeking agent exclusive of said particles in a concentration sufficient to combine with and selectively direct the particles to the atherosclerotic lesion.
Claim 5
Dependent Claim 15 words
The process of claim 4 wherein said atherosclerotic seeking agent is an atherosclerotic specific antibody.
Claim 6
Dependent Claim 23 words
The process of claim 1 including the use of a localized field to localize the particles in a specific area prior to treatment.
