Title: Magnetic field applicator to heat magnetic or magnetizable substances or solids in biological tissue
IPC: A61F7/00
Filed: 2000-07-18
Abstract: A magnetic field applicator to heat magnetic substances in biological tissue, having a magnetic yoke with two pole shoes across from each other and separated from each other by a distance that defines the magnetic field exposure volume produced by the applicator, and with two magnetic coils, one assigned to each of the two pole shoes, to produce a magnetic field. The magnetic yoke and the pole shoes consist of ferrite segments assembled together. Additionally, the magnetic field applicator is composed of a magnetic yoke having two parallel vertical yoke elements of identical geometry spaced apart a distance from each other, and two transverse yoke elements disposed between said vertical yoke elements. The pole shoes, surrounded by disk-shaped magnetic coils, are attached to the center of said transverse yoke elements and oppose each other over a prescribed distance. One transverse yoke element with surrounding magnetic coil is designed to be an adjustable component relative to the other transverse yoke element in order to adjust the width of the space separating the pole shoes, which defines the magnetic field exposure volume. In this manner an effective and efficient magnetic field applicator is created to carry out hyperthermia treatments and thermo-ablation procedures, as well as having uses in other medical applications.
