Abstract: An apparatus for treatment of a portion of a biological body with magnetic fields having a device adapted for producing spin resonances for treatment within a portion of the biological body to be treated. The apparatus includes a magnet for producing a magnetic field, a coil system for producing a magnetic alternating field at right angles to the magnetic field, control electronics for actuation of the magnet and the coil system adapted to produce nuclear spin resonance in at least a portion of a biological body, and a device for repeated actuation of the control electronics to produce a defined sequence of nuclear spin resonances. The sequence of nuclear spin resonances produced by the device is determined by the spin-lattice relaxation time T1of at least one portion of the biological body, and has a repetition rate of approximately 3T1.

Abstract: The invention relates to a device for magnetic field therapy of human, animal or plant tissue. The invention comprises at least one unit for generating a magnetic field with a statical component which is constant in time and an alternating field component at the location of the tissue which is to be treated. The magnetic alternating field has a predetermined cell biorhythm frequency v2 and is essentially monochromatic. The inventive device additionally comprises a unit for amplitude modulation of the magnetic alternating field with a modulation frequency v0.

Abstract: In a process and an apparatus for the detection of the contact and/or the interaction of a catheter arranged in a patient's vessel, in particular in a patient's blood stream, with the patient's tissue, in order to contribute to an improved detection of this contact or to make it possible for the first time to permit statements during an ablation process regarding the ablation depth or regarding the interaction with the tissue, a device is provided for the detection of a voltage at at least one catheter electrode, wherein the voltage between the catheter electrode and a further electrode is measured, and wherein the further electrode is a neutral electrode in contact with the patient's body or a further electrode installed on the catheter.
