Indications for Use

Indications for use in applying therapeutic deep heat in body tissues for the treatment of selected medical conditions such as disorders of the musculoskeletal system, muscle spasm, joint stiffness, contractures, and chronic inflammatory or infective conditions such as tenosynovitis, bursitis, synovitis and chronic inflammatory pelvic diseases.

Device Story

ThermoPro is a shortwave diathermy device delivering electromagnetic energy at 27.12 MHz to induce deep tissue heating via eddy currents. The device consists of a metal enclosure with a touchscreen interface and a monode electrode applicator. A sine wave synthesizer and RF power amplifier generate energy in constant or pulsed modes. Operated by clinicians in a medical setting, the user selects therapy parameters (mode, pulse frequency, duty cycle, power, duration) via the touchscreen. A coupling indicator on the display assists the user in positioning the applicator relative to the patient. The device provides pain relief, reduces muscle spasms, increases local blood flow, and treats chronic inflammatory conditions. Clinical benefit is derived from the conversion of electrical energy into heat directly within the tissue.

Clinical Evidence

Bench testing only. The device was evaluated for compliance with ANSI/AAMI/ISO 10993-1 (biocompatibility), IEC 60601-1 (electrical safety), IEC 60601-1-2 (EMC), IEC 60601-1-6 (usability), IEC 60601-2-3 (shortwave therapy performance), IEC 62366-1 (usability engineering), ISO 62304 (software lifecycle), and ISO 14971 (risk management). All components and systems met required specifications.

Technological Characteristics

Shortwave diathermy; 27.12 MHz frequency; 100W output power (200W pulsed); metal enclosure; monode electrode applicator; Type BF applied part; Class I protection; touchscreen interface; constant wave and pulsed modes; 100-240 VAC power source. Complies with IEC 60601-2-3, IEC 60601-1, and ISO 62304.

Indications for Use

Indicated for patients requiring therapeutic deep heat for musculoskeletal disorders, muscle spasms, joint stiffness, contractures, and chronic inflammatory or infective conditions including tenosynovitis, bursitis, synovitis, and chronic inflammatory pelvic diseases.

Regulatory Classification

- 5. Indications for Use Statement:
Indications for use in applying therapeutic deep heat in body tissues for the treatment of selected medical conditions such as disorders of the musculoskeletal system, muscle spasm, joint stiffness, contractures, and chronic inflammatory or infective conditions such as tenosynovitis, bursitis, synovitis and chronic inflammatory pelvic diseases.

Generally accepted indications for use:

- Pain Relief ●
- . Contractures
- Reduce Muscle Spasm ●
- Localized increase Blood Flow ●
- Chronic Inflammatory Conditions ●
- . Bursitis
- . Decrease Joint Stiffness
- Tenosynovitis ●
- Synovitis ●
- Chronic Inflammatory Pelvic Disease ●
- 6. Technological Characteristics:

Shortwave diathermic therapy relies on the conversion of electric power into heat energy that takes place directly inside the tissue, as opposed to a typical heat treatment method in which heat (e.g. heat packs) is supplied from the outside of the tissue. A highfrequency field generates eddy currents in the treated tissues that lead to molecular excitations and convert the electrical energy into heat.

The energy can be applied either in constant wave mode or in pulsed mode. To run a therapy, the user selects the mode, pulse frequency and duty cycle (if applicable), power level and duration of therapy .The coupling is dependent on the distance between the applicator and the patient and can easily be controlled by supervising the coupling indicator on the display.
