Apparatus for repetitive nerve stimulation for the degradation of adipose tissue by means of inductive magnetic fields

摘要

Free-standing device with a magnetic field coil as a stimulation coil for the therapeutic treatment of obesity. The device comprises a large-area stimulation coil in body-adapted geometry by means of which an electric field is generated in the tissue by induction. This stimulates a largely painless muscle contraction, which leads to a breakdown of fatty tissue. In conjunction with a pulse generator electromagnetic stimulation pulses are generated with a duration of 100 microseconds to 300 microseconds and a stimulation frequency of 10 Hz to 30 Hz over a treatment period of 1 min to 45 min. The electrical field strengths achieved in the body tissue at the stimulation site are in the range of 0.1 to 1 V / cm. The Joule heat in the coil is removed by means of an air blower. Devices on the structure allow a patient-optimized positioning of the coil. The pulse duration, pulse amplitude and pulse shape as well as the stimulation frequency are adjustable in regions or can be automatically optimized with regard to optimal muscle contraction via camera and computer-assisted image analysis.
