Abstract

An apparatus for promoting healing of body tissue composed of a coil arranged to be applied to the affected body part and to be connected to a low frequency a.c. source to produce a magnetic field within the region to be treated, and at least two sheetlike electrodes associated with the coil and spaced from one another, the electrodes being arranged to be located at respectively opposite sides of the region to be treated and to be connected to a source of a low frequency voltage to produce an electric field within the region to be treated at the same time as the magnetic field.

Claims

1. In apparatus for promoting healing processes and comprising a coil adapted to be applied to a part of the body to be treated and adapted to be connected with a source for a varying current with a low frequency for causing the coil to produce a corresponding magnetic field in the longitudinal direction of and which pervades the part of the body to be treated, the improvement comprising two sheet-like electrodes associated with said coil, disposEd with a spacing between them and arranged to be connected with a source of low frequency varying voltage for producing an electric field which pervades the part of the body to be treated simultaneously with the magnetic field, said electrodes extending at least approximately parallel to the surface occupied by the windings of the coil.

2. An apparatus in accordance with claim 1 wherein the coil is composed of a number of flat coils connected to each other in a jointed manner, with at least two of said coils being provided with a respective one of said sheet-like electrodes.

3. An apparatus in accordance with claim 1 further comprising a rod-shaped body of a tissue-compatible insulating material, and a receiving coil carried by said body, and wherein said two electrodes are electrically connected to said receiving coil and extend adjacent to the surface of said body.

4. An apparatus in accordance with claim 3 wherein said electrodes are provided with an insulating surface.

5. In apparatus for promoting healing processes and comprising a coil adapted to be applied to a part of the body to be treated and adapted to be connected with a source for a varying current with a low frequency for causing the coil to produce a corresponding magnetic field, which pervades the part of the body to be treated, the improvement comprising two insulated sheet-like electrodes, disposed with a spacing between them and arranged to be connected with a source of low frequency varying voltage for producing an electric field which pervades the part of the body to be treated simultaneously with the magnetic field, a bone splint implantate member;

a receiving coil arranged on such implantate member and magnetically linked to said first-recited coil, said receiving coil having terminals each connected to a respective one of said two insulated sheet-like electrodes and constituting said source of voltage.
