Systems and methods which remove material from blood vessel walls
First Claim
1. A method for removing molecules in a layer of plaque from a position along a wall of a blood vessel through which blood flows in a direction, comprising:
- applying an electric field to at least a portion of a person'"'"'s body, wherein the electric field is produced by at least one external component to the body, the electric field having a net direction predominantly orthogonal to the direction of the flow of blood through the vessel, the field produced by the at least one external component being 0.01 Tesla to 5 Tesla of sufficient strength, without the need for an energy focusing device placed within the person'"'"'s body, to dissociate a first molecule in the layer of plaque from another molecule in the layer, or from a molecule which forms the blood vessel wall, by severing a bond which otherwise stabilizes the position of the first molecule within the layer of plaque.

Abstract
Systems and methods for removing plaque from blood vessels by applying constant or time varying magnetic or electrical fields. In one embodiment a system includes winding configurations positioned about a central axis along which a body region may be placed. Each winding configuration generates a magnetic field in a direction which passes through the body region. A first winding configuration generates a first magnetic field component perpendicular to a second magnetic field component generated by a second winding configuration. In a related method for removing a deposit of plaque from a position along a wall of a blood vessel a magnetic field is applied which has a net direction predominantly orthogonal to the direction of the flow of blood through the vessel.

4. A method for removing molecules in a layer of plaque positioned along a wall of a blood vessel through which blood flows in a direction, comprising:
-
applying a magnetic field to at least a portion of a person'"'"'s body, wherein the magnetic field is produced by at least one external component to the body, the magnetic field including a component having a direction predominantly orthogonal to the direction of the flow of blood through the vessel, the field produced by the at least one external component being 0.01 Tesla to 5 Tesla of sufficient strength, without the need for an energy focusing device placed within the person'"'"'s body, to cause charge separation of conductive carriers in the blood resulting in an electric field; wherein said electric field alters association of non-polar molecules or slightly polar molecules which have accumulated along the wall of the blood vessel by providing energy greater than the energy which binds the molecules together thereby contributing to dissociation of the molecules and allowing the molecules to travel with the blood in the vessel. - View Dependent Claims (5, 6)
