Problems solved by technology

[0004] However, the technology is critical in producing a practical therapeutic cycle for cartilage tissue / subchondral bone for application in the human body, i.e. capable of acting and modifying damaged or inflamed cartilage and subchondral bone in a sensitive, specific and dramatic manner. The device aspect of the structure has not been successful
[0005] The lack of adequate preclinical experiments that allow the identification and combination of optimal (i.e. effective) EMF parameters (amplitude, waveform frequency, and duration of exposure) may lead to incorrect selection of parameters characterizing EMF and thus not obtaining any therapeutic effect, as in Literature (Effects of pulsed electromagnetic fields on articular hyaline cartilage: review of experimental and clinical studies) by Fini M et al.

Embodiment Construction

[0016] Referring to Figure 1, 1 indicates (as a whole) a device for regeneration and prevention of degeneration of cartilage tissue and subchondral bone and proliferation of chondrocytes by means of pulsed electromagnetic fields.

[0017] The device 1 comprises a signal generator device 3 (of known type) controllable by a microprocessor unit 4 and adapted to output a signal u(t) of periodic type.

[0018] The microprocessor unit 4 is connected to a user interface 6 (e.g. keyboard / video) to select the waveform (square wave, sawtooth, linear ramp, etc.) of the signal u(t) and to adjust the frequency and duty cycle. The user interface 6 also allows the signal u(t) to be generated for a time interval Tmax which can be selected as desired.

[0019] The signal generator means 3 is connected at the output to the input of a variable gain power amplifier 8 which outputs a power signal U which is transmitted to a pair of solenoids or to a single solenoid (of known type) 12. (t), the s...

Abstract

Device for the regeneration and prevention of degeneration of the cartilage and subchondral bone, the proliferation of chondrocytes and for blocking or reducing the fibroblastic evolution of chondrocytes and mesenchymal cells by means of electromagnetic waves comprising a device for generating a periodic signal u(t) and a power amplifier suitable for applying the signal u(t) to a pair of solenoids for the generation of an electromagnetic field M(t) addressed towards a portion of human / animal body containing cartilage. Setting means are provided for the generation of an electromagnetic field having intensity between 0.5 and 2 milliTesla, frequency between 37 and 75 Hz and period of application between 1 hour and 9 hours.

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...
