Device Story
Four-channel combination unit for therapeutic ultrasound and muscle stimulation; used in clinical settings by healthcare professionals. Inputs: user-selected parameters via membrane panel and control knobs. Operation: microprocessor-controlled delivery of 1 and 3 MHz ultrasound (via interchangeable applicators) and electrical stimulation (premodulated, biphasic, medium frequency, Hi-Volt, Russian, DC waveforms). Outputs: therapeutic ultrasound energy and electrical stimulation waveforms. Device provides tactile/audio feedback and visual guidance via LEDs and LCD. Clinician monitors four channels simultaneously to adjust treatment protocols. Benefits: pain relief, muscle spasm reduction, increased blood flow, improved range of motion, and prevention of disuse atrophy/venous thrombosis.
Clinical Evidence
Bench testing only. No clinical data presented. Performance verified through electrical and ultrasonic output measurements, compliance with safety standards (UL 2601-1, CSA C22.2, IEC/EN 60601 series), and comparison of waveform characteristics against predicate devices.
Technological Characteristics
Four-channel combination unit; metal casing; AC line powered. Ultrasound: 1 and 3 MHz, continuous/pulsed modes, piezoelectric transducers. Electrical stimulation: premodulated, biphasic, medium frequency, Hi-Volt, Russian, DC waveforms. Microprocessor-controlled. Standards: ISO 14971, UL 2601-1, CSA C22.2 No 601.1-M90, IEC/EN 60601-1, 60601-1-2, 60601-2-5, 60601-2-10, 21 CFR 1050.10.
Indications for Use
Indicated for patients requiring therapeutic deep heat for sub-chronic conditions (adhesive capsulitis, bursitis, myositis, soft tissue injuries, scar tissue, capsular tightness); symptomatic relief of chronic intractable, post-traumatic, or post-surgical pain; relaxation of muscle spasms; increased local blood circulation; prevention/retardation of disuse atrophy; muscle re-education; maintenance/increase of range of motion; and prevention of post-surgical venous thrombosis.
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.

### Description of Proposed Device:
The Sonicator® Plus 940 , Model ME 940 is a four-channel combination unit for therapeutic ultrasound and muscle stimulation. The microprocessor controlled Sonicator Plus 940 provides premodulated medium frequency and symmetrical biphasic waveforms with enhanced reliability and ease of use. In addition the Sonicator Plus 940 offers 1 and 3 MHz ultrasound using a variety of interchangeable applicators.
The four-channel Sonicator Plus 940 allows the clinician to utilize up to two different waveforms using four channels simultaneously. The clinician can choose between several different amplitude modulation options such as the surge, reciprocation and amplitude modulation (interferential only, vector rotation). The interferential and premodulated modes offer frequency modulation as well as a static frequency option.
The membrane panel provides both tactile and audio feedback when buttons are pressed. Blinking LED's guide the operator through the easy setup routine.
Large, soft-touch control knobs make adjusting power for ultrasound and stimulation easy to accomplish with no guesswork involved. A large LCD output display allows the clinician to monitor four channels simultaneously for four channel combination treatment protocols. It also allows the operator to adjust both channels of an interferential protocol simultaneously while monitoring the current.

The Sonicator Plus 940 can provide electrical stimulation only. ultrasound only and combination therapy with the pre-modulated, biphasic and medium frequency waveforms

Trade/Device Name: Sonicator® Plus 940, Model ME 940 Regulation Number: 21 CFR 890.5860 Regulation Name: Ultrasound and muscle stimulator Regulatory Class: Class II Product Code: IMG, GZJ, LIH Dated: July 3, 2007 Received: July 9, 2007
Dear Mr. Fleming:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at 240-276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at 240-276-3464. You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
