The Gallieon -1 SYSTEM is for prescription use only.

The device is indicated for emitting energy in the infrared spectrum to provide topical heating tissue temperature for temporary relief of minor muscle spasm, pain and stiffhess associated with arthritis and promoting relaxation of the muscle tissue and to temporarily increase local blood circulation.

Gallieon-1 is a non-invasive, low energy infrared therapeutic medical laser that is intended to perform laser therapy in the health care centers, physical therapy laboratories, and family practices. It is composed of adjustable output powers, handpiece (emitter) for the delivery of light, on/off button to activate and deactivate the infrared emission. Also Gallieon-1 meets FDA requirement of the skin temperature test and the electromagnetic compatibility and electrical safety test.

The provided FDA 510(k) summary for the Gallieon-1 device does not include detailed information on acceptance criteria or a specific study proving the device meets performance criteria. The document focuses on demonstrating substantial equivalence to predicate devices based on intended use, technical characteristics, and safety standards, rather than providing a performance study with detailed acceptance criteria.

However, based on the available information, we can infer some aspects and highlight what is missing.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document does not describe a clinical study or performance test involving a specific "test set" in the context of assessing device efficacy or accuracy against ground truth. The evaluation is primarily focused on demonstrating safety through adherence to standards and substantial equivalence to existing devices. Therefore, these details are not provided.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

As no specific "test set" for performance evaluation is described, information regarding experts for ground truth establishment is not applicable and not provided.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable, as no dedicated test set for performance evaluation is described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance

The Gallieon-1 is an infrared lamp for therapeutic heating, not an imaging or diagnostic device that would typically involve "human readers" or "AI assistance" in the sense of image interpretation. Therefore, an MRMC comparative effectiveness study is not relevant to this device type, and no such study is mentioned.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The Gallieon-1 is a physical therapy device that delivers infrared energy. It does not contain an algorithm in the sense of AI or image processing that would have a "standalone" performance. Its "performance" would be related to its ability to generate heat and deliver infrared radiation within specified parameters, which is assessed through engineering and safety tests rather than an algorithm-only evaluation.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For a device like the Gallieon-1, "ground truth" would primarily relate to its physical properties and safety parameters, such as:

• Irradiance/Power Output: Measured by calibrated optical power meters.
• Wavelength: Measured by spectrometers.
• Temperature Safety: Measured by thermocouples/IR thermometers on skin models or in-vivo studies (though no direct study with results is provided, only a statement of meeting the "skin temperature test").
• Electrical Safety & EMC: Determined by compliance with established electrical and electromagnetic compatibility standards, using specialized testing equipment.

The document states, "The Gallieon-1 was tested extensively to ensure conformance to applicable standards and FDA regulations," and "meets the FDA requirement of the skin temperature test and the electromagnetic compatibility and electrical safety test." This implies that the "ground truth" for safety and basic technical specifications were compliance with these established standards and validated physical measurements. There is no mention of clinical outcomes data or expert consensus on efficacy for the purpose of this 510(k) summary, as substantial equivalence is the primary pathway.

8. The sample size for the training set

Not applicable. As a physical therapeutic device, there is no "training set" in the context of machine learning or algorithmic development. Its design and manufacturing are based on established engineering principles and safety standards for infrared lamps.

9. How the ground truth for the training set was established

Not applicable, as there is no "training set" for this device.
