Intended Use

Therapeutic Ultrasound - Pain relief - Reduction of muscle spasms - Localized increase in blood flow - Increase range of motion of contracted joints using heat and stretch techniques

Device Story

Sonomed IV and Sonomed V are ultrasonic diathermy devices used in clinical settings by therapists. The device generates ultrasound energy via a piezoelectric crystal (PZT) housed in a treatment head (applicator). The therapist applies the head to the patient's body using a contact gel. The device transforms electrical energy into mechanical ultrasonic beams, which are absorbed by tissues and converted into deep heat. This thermal effect increases microcirculation, reduces pain perception, decreases inflammatory activity, and aids tissue recovery. The device operates at 1 MHz or 3.3 MHz frequencies, with higher frequencies targeting more superficial tissues. The therapist controls treatment parameters, including intensity and mode (pulsed or continuous), to achieve therapeutic goals. The device is intended to improve patient outcomes by facilitating joint mobility and reducing musculoskeletal discomfort.

Clinical Evidence

No clinical data were included in this submission. Substantial equivalence is supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and performance testing for ultrasonic physiotherapy equipment (IEC 60601-2-5).

Technological Characteristics

Class II medical electrical equipment, Type BF. Uses PZT (Zirconia ceramic) piezoelectric crystals for ultrasound generation. Operates at 1 MHz and 3.3 MHz. Features include pulsed/continuous modes, 0.1-3.0 W/cm² intensity, and collimated beam output. Powered by 100-240V AC. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-2-5, IEC 62304, and ISO 10993-1.

Indications for Use

Indicated for patients requiring therapeutic ultrasound for pain relief, reduction of muscle spasms, localized increase in blood flow, and increased range of motion of contracted joints via heat and stretch techniques.

Regulatory Classification

Identification

An ultrasonic diathermy 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.

Dear Bruno Milhoci:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

Indications For Use

Therapeutic Ultrasound:

- Pain relief

- Localized increase in blood flow
- Increase range of motion of contracted joints using heat and stretchtechniques

Subject Device Description

The SONOMED apparatus is ultrasound equipment for therapy, which has been developed in accordance with the safety standards IEC 60601-2 and IEC 60601-2 and IEC 60601-2-5, class II, type BF, which makes it a safe apparatus of high reliability for the therapist and the patient.

SONOMED is medical electric equipment which provides therapeutic ultrasound treatment. Ultrasound is a mechanic stimulus directed to the body through ultrasonic beam emitted by a transducer/applicator, better known as head. This ultrasound is produced in the head through a piezoelectric crystal and is transmitted to the body through the aluminum surface of the head and a contact agent (gel). Depending on how the ultrasound beam passes through the tissues, its energy is gradually and selectively absorbed being transformed into heat, among other effects. This increase in temperature causes biological changes in the tissues as for instance increase in micro circulation, a reduced perception of pain, a reduction in inflammatory activity and an increase in the reestablishing rate of delicate tissues. The higher the ultrasound frequency, the more superficial will be its absorption.

#### Discussion:

The subject device and the predicate device have similar intended use, principles of operation, and output characteristics. Of note:

- -Treatment time: the predicate has a higher treatment time, if the practitioner needs more than 20 minutes the treatment could be restarted.
- -Piezoelectric Material: They have the same Zirconia ceramic piezoelectric family.
- -Maximum Value of the Output Power: The output power of the predicate is higher, as the ERA is larger, the output density power is equal.
- -Penetration depth: The subject device and the sonopulse has the same penetration depth

### Non-Clinical Performance Data:

The Sonomed was tested in accordance with these standards:

- IEC 60601-1 - Medical electrical equipment - Part 1: General requirements for basic safety and essential performance
- IEC 60601-1-2 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests
- IEC 60601-2-5 Medical electrical equipment – Part 2-5: Particular requirements for the basic safety and essential performance of ultrasonic physiotherapy equipment
- . IEC 62304 Medical device software – Software life cycle processes

{9}------------------------------------------------

- . ISO 10993-1 Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process
Clinical performance Data:

No clinical data were included in this submission.

Conclusion:

The documentation submitted in this premarket notification demonstrates that the subject devices have comparable features and performance and, therefore, are substantially equivalent to the identified predicate device.
