Intended Use

Ultrasound for use in applying deep heat can be used for treatment of selected medical conditions such as the relief of pain, muscle spasms and joint contractures. These conditions may be associated with adhesive capsulitis; bursitis with slight calcification, myositis and soft tissue injuries. The Forte CPS Combo, while using any of the applicators available for this device, can provide therapeutic deep heating between 40° and 45°C in all of its operating modes. For VMS. Russian, & Monophasic Hi-Volt - Relaxation of muscle spasms - Prevention or retardation of disuse atrophy - Increasing local blood circulation - Muscle re-education - Maintaining or increasing range of motion - Immediate postsurgical stimulation of calf muscles to prevent venous thrombosis For Interferential, Microcurrent, and Premodulated - Symptomatic relief of chronic, intractable pain - Management of pain associated with post-traumatic or post-operative conditions

Device Story

Forte CPS series (200/400 Stim, Ultrasound, Combo) provides therapeutic modalities including ultrasound, VMS, Russian, Monophasic Hi-Volt, Interferential, and Microcurrent stimulation. Device used in clinical settings by healthcare professionals. Ultrasound component delivers deep heat (40-45°C) for soft tissue conditions. Electrical stimulation modes target muscle rehabilitation and pain management. Output parameters controlled by clinician to achieve specific physiological effects like muscle contraction or pain relief. Benefits include improved range of motion, pain reduction, and muscle function restoration.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use.

Technological Characteristics

Multi-modal therapeutic device combining ultrasound and electrical stimulation (VMS, Russian, Monophasic Hi-Volt, Interferential, Microcurrent). Provides deep heating (40-45°C). Class II device. No specific materials or software architecture details provided.

Indications for Use

Indicated for patients requiring deep heat therapy for pain, muscle spasms, joint contractures, adhesive capsulitis, bursitis, myositis, and soft tissue injuries. Also indicated for muscle spasm relaxation, atrophy prevention, blood circulation improvement, muscle re-education, range of motion maintenance, venous thrombosis prevention via calf stimulation, and management of chronic, intractable, post-traumatic, or post-operative pain.

Regulatory Classification

Identification

An ultrasound and muscle stimulator for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body ultrasonic energy at a frequency beyond 20 kilohertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies. The device also passes electrical currents through the body area to stimulate or relax muscles.

Dear Mr. Elrod:

We have reviewed your Section 510(k) notifications of intent to market the devices referenced above and we have determined these devices are substantially equivalent (for the indications for use stated in the enclosures) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the devices, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your devices are classified (see above) into either class II (Special Controls) or class III (Premarket Approval), they may be subject to such additional controls. Existing major requlations affecting your devices can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. ਜੋ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory
