Intended Use

A hand held cutaneous electrode to be used with Dynatronics Solaris devices to apply electrical stimulation and/or apply heat and cooling to the skin.

Device Story

Handheld cutaneous electrode accessory for Dynatronics Solaris series consoles; used by clinicians to deliver electrical stimulation and thermal therapy (hot/cold) to patient skin. Device consists of handle, treatment head, and thermo-electric Peltier chip. Solaris console provides power, communication, and electrical stimulation waveforms (Biphasic, Russian, HiVolt, IFC, Premodulated, Microcurrent). Peltier chip in treatment head transfers thermal energy (hot: 90-112°F; cold: 39-60°F). Practitioner manually applies probe to patient tissue. Output affects clinical decision-making by providing combined electrotherapy and thermal modalities for pain management. Benefits include localized therapeutic thermal and electrical stimulation delivery.

Clinical Evidence

Bench testing only. Waveform analysis confirmed electrical stimulation outputs are equivalent to the predicate. Thermal data verified temperatures consistently fall within targeted hot (90-112°F) and cold (39-60°F) ranges. Dielectric strength and electromagnetic compatibility testing performed per EN60601-1 and EN60601-1-2.

Technological Characteristics

Materials: 6061 Aluminum treatment face, ABS plastic handle. Energy: Electrical stimulation (via Solaris console) and thermal energy (via Peltier thermo-electric chip). Dimensions: 2" x 3.6" x 10". Connectivity: Wired connection to Solaris console. Standards: EN60601-1 (dielectric strength), EN60601-1-2 (EMC).

Indications for Use

Indicated for patients with acute or sub-acute pain requiring electrical stimulation and/or thermal therapy (heat/cold) applied via a handheld cutaneous electrode.

Regulatory Classification

Identification

A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation.

# 2. PREDICATE DEVICE:

Dynatron ThermoStim probe - K120835 (August 20, 2012)

# 3. DESCRIPTION:

The Dynatron Peltier ThermoStim probe is used to provide therapeutic electrical stimulation and thermal therapy treatments. The probe consists of a handle with a treatment head and connections to a Dynatron Solaris series controlling console for power and communications with a port for connection to electrical stimulation outputs. The probe acts as an electrode for therapeutic electrical current provided by a Dynatron Solaris device in the delivery of electrical stimulation therapy. The treatment head transfers thermal energy (hot or cold) supplied from a thermo-electric chip.

The probe is a passive, manual therapy accessory. Treatment cycles are controlled through previously cleared Dynatron Solaris series electrical stimulation devices.

The probe has a rectangular wedge treatment face of approximately 1¼³ x 2¼" with rounded edges. The maximum surface area that could come in contact with a patient is approximately 38 cm-.

# 4. INDICATIONS FOR USE:

A hand held cutaneous electrode to be used with Dynatronics Solaris devices to apply electrical stimulation and/or apply heat and cooling to the skin.

The Indications for Use stated in this submission match word for word the Indications for Use cleared for the predicate device.

# 5. TECHNICAL ANALYSIS:

The Dynatron Peltier ThermoStim probe generates therapeutic benefits as described in allowed claims through the delivery of electrical stimulation and thermal energy to targeted tissues.

The probe allows the practitioner to manually apply various electrical stimulation treatments (limited to modalities available from the FDA cleared Dynatronics Solaris series devices) as well as thermal energy (hot or cold). The delivery of hot thermal energy has a targeted range of 90 - 112° Fahrenheit and the cold thermal energy has a targeted range of 39 - 60° Fahrenheit.

#### Performance Characteristics

The probe has a treatment face with a rectangular wedge shape and rounded edges. The treatment face is approximately 11/4" x 21/4" and the tip of the wedge is approximately ½' high. The probe acts as an accessory to provide the following clectrotherapy options:

Biphasic, Russian, HiVolt, Interferential Current (IFC), Premodulated (IFC), and Microcurrent

The probe is designed to deliver thermal energy with the following range options.

Hot = 90 -- 1120 Fahrenheit

Cold = 39 - 60° Fahrenheit

Non-clinical Bench Testing

Wave forms of cach electrotherapy output were captured from a Dynatron Solaris device through the Peltier ThermoStim probe and the predicate ThermoStim probe. Analysis of the wave forms for delivery of electrical stimulation treatments show no differences with the output from the predicate device compared to the subject device.

The Peltier ThermoStim probe will be tested for dielectric strength per EN60601-1 and for electromagnetic compatibility per EN60601-1-2. Per the March 2000 F.DA Office of Device Evaluation guidance document "Use of Standards in Substantial Equivalence Determinations" these tests will be completed prior to marketing the device.

Thermal data was collected from the Peltier ThermoSTIM probe in "hot" and "cold" modes. Results showed temperatures consistently falling in the targeted thermal ranges.

Both devices use the Dynatron Solaris controlling console to deliver electrical stimulation through the probes as a cutaneous electrode. The electrotherapy wave form outputs from the predicate and subject are equivalent. Both probes provide heating and cooling in the same thermal ranges. Both probes have treatment areas large enough for a safe current density to mitigate risks of patient injury. Patient contact surfaces for both the predicate and subject probe are identical aluminum composition. From a non-clinical analysis we conclude that the two probes are substantially equivalent.

It is our assessment that the Dynatron Peltier ThermoStim probe is substantially equivalent to the predicate Dynatron ThermoStim probes (applicable "K ' number listed above) because both devices are labeled for the same Indications for Use, both deliver equivalent electrotherapy outputs, both deliver equivalent thermal outputs, and both are a hand held cutaneous electrode accessory controlled by a Dynatron Solaris console. The only distinction is the method by which the thermal energy is delivered and the shape of the electrode.

# 7. SAFETY AND EFFECTIVENESS SUMMARY:

There are no substantive differences between the product defined in this 510(k) submission and the predicate device is similar to the technology that is currently used in other similar medical devices. This device is subject to development and documentation as required in the Quality System Regulation, 21 CFR Part 820, under design/change control. and is subject to verification and validation to applicable standards / guidance documents. The sum of bench test results and design control outcomes allows us to conclude that the Dynatron Peltier ThermoStim probe is as safe and effective in delivering treatments when used as indicated in specific applications under a clinician's supervision / therapy program as the predicate probes.
