Description

technical field

[0001] The present invention relates to a device for regeneration and prevention of cartilage tissue and subchondral bone degeneration and chondrocyte proliferation by means of pulsed electromagnetic fields. Background technique

[0002] Techniques are known for the treatment of the human body by pulsed electromagnetic fields, in which a solenoid is powered by a time-variable electrical signal (e.g., a current-variable signal) to generate a cartilage tissue / subchondral bone-containing A portion of the pulsed electromagnetic field in which induced microcurrents are formed for healing and / or ameliorating inflammatory processes and / or damage present in the treated part of the body.

[0003] Scientific observations have been reported that suggest the possibility of useful application of pulsed electromagnetic fields for the treatment of articular cartilage and subchondral bone.

[0004] However, the technology is critical in producing a practical therapeutic cyc...
