Indications for Use
Diathermy is used therapeutically to increase the temperature of tissues. It is generally accepted that heat produces the following desirable therapeutic effects: - Relieves pain - Increases the extensibility of collagen tissues - Decreases joint stiffness - Relieves muscle spasm - Increases local blood flow Megapulse Shortwave Diathermy system is indicated for use in the following conditions or applications: - Disorders of the musculoskeletal system o Muscle spasm o Joint stiffness o Joint contractures - Chronic inflammatory or infective conditions o Tenosynovitis o Bursitis o Synovitis o Chronic inflammatory pelvic diseases
Device Story
Megapulse III Shortwave Diathermy is a therapeutic device used in clinical settings by healthcare professionals to increase tissue temperature. It delivers shortwave electromagnetic energy to the patient's body to induce deep heating. This heat relieves pain, increases collagen tissue extensibility, decreases joint stiffness, reduces muscle spasms, and increases local blood flow. The device is operated by clinicians to treat specific musculoskeletal and chronic inflammatory conditions. The output is controlled thermal energy, which the clinician applies to the target area to achieve the desired physiological effects, thereby aiding in rehabilitation and symptom management.
Clinical Evidence
No clinical data provided; bench testing only.
Technological Characteristics
Shortwave diathermy system; operates by delivering electromagnetic energy to induce tissue heating. Class II device (21 CFR 890.5290).
Indications for Use
Indicated for patients requiring therapeutic tissue heating for musculoskeletal disorders (muscle spasm, joint stiffness, joint contractures) and chronic inflammatory/infective conditions (tenosynovitis, bursitis, synovitis, chronic inflammatory pelvic diseases).
Regulatory Classification
Identification
A nonthermal shortwave therapy is a prescription device that applies to the body pulsed electromagnetic energy in the RF bands of 13.56 MHz or 27.12 MHz and that is intended for adjunctive use in the palliative treatment of postoperative pain and edema of soft tissue by means other than the generation of deep heat within body tissues as described in paragraph (a) of this section.
Special Controls
*Classification: Class II (special controls).* The device is classified as class II. The special controls for this device are:(i) Components of the device that come into human contact must be demonstrated to be biocompatible. (ii) Appropriate analysis/testing must demonstrate that the device is electrically safe and electromagnetically compatible in its intended use environment. (iii) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use. Non-clinical performance testing must characterize the output waveform of the device and demonstrate that the device meets appropriate output performance specifications. The output characteristics and the methods used to determine these characteristics, including the following, must be determined: (A) Peak output power; (B) Pulse width; (C) Pulse frequency; (D) Duty cycle; (E) Characteristics of other types of modulation that may be used; (F) Average measured output powered into the RF antenna/applicator; (G) Specific absorption rates in saline gel test load or other appropriate model; (H) Characterization of the electrical and magnetic fields in saline gel test load or other appropriate model for each RF antenna and prescribed RF antenna orientation/position; and (I) Characterization of the deposited energy density in saline gel test load or other appropriate model. (iv) A detailed summary of the clinical testing pertinent to use of the device to demonstrate the effectiveness of the device in its intended use. (v) Labeling must include the following: (A) Output characteristics of the device; (B) Recommended treatment regimes, including duration of use; and (C) A detailed summary of the clinical testing pertinent to the use of the device and a summary of the adverse events and complications. (vi) Nonthermal shortwave therapy devices marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with these special controls.
