## Device Story

The CT 1000 SonicStimu Combo is a multi-modality therapeutic device combining ultrasound and electrical muscle stimulation (TENS, IFC, NMS, Microcurrent, EMS, Hi-Volt, Russian). It delivers deep heat via ultrasound for musculoskeletal conditions and electrical stimulation for pain management and muscle rehabilitation. The device is intended for clinical use by healthcare professionals or for prescription-based patient use. It operates by applying ultrasound transducers or electrical stimulation electrodes to the patient's skin. The provider selects the modality and parameters based on the patient's condition to achieve pain relief, muscle relaxation, or improved circulation. The device provides therapeutic benefits by addressing chronic pain, joint stiffness, and muscle atrophy.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Combination device providing therapeutic ultrasound and electrical stimulation (TENS, EMS, IFC, NMS, Microcurrent, Hi-Volt, Russian). Class II device (Product codes: IMG, GZJ, LIH). Operates via electrical energy conversion to mechanical (ultrasound) and electrical (stimulation) outputs. Form factor is a tabletop or portable console with external applicators/electrodes.

## Regulatory 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 Kang Jian Ping:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
