The CryOmega is a disposable device intended for the surgical destruction of target tissue by applying cryogenic gases at extreme low temperatures. The list below shows examples of the type of lesions that can be treated.
-Genital Lesions -Molluscum Contagiosum -Seborrheic Keratoses -Skin Tags -Verruca Plantaris -Verruca Vulgaris -Verruca Plana -Actinic Keratosis -Lentigo
The CryOmega device is designed to dispense a continuous stream of liquid nitrous oxide when actuated. The device contains a 16g cartridge of nitrous oxide that is dispensed once the device is activated. Physicians or medical professionals can then dispense the gas for use in procedures requiring the destruction of tissue using the extreme cold of nitrous oxide (-89°C). Unlike the predicate device, the CryOmega is designed to be self contained and disposable after all of the liquefied gas has been dispensed.
The provided text is a 510(k) Premarket Notification Summary for the CryOmega device. It focuses on demonstrating substantial equivalence to a predicate device (Cryoprobe-C) rather than presenting a standalone study with detailed acceptance criteria and performance metrics typically found for AI/software-as-a-medical-device (SaMD) clearances.
Therefore, much of the requested information regarding AI device testing (such as sample sizes for test/training sets, expert ground truth, adjudication methods, MRMC studies, or standalone performance for an algorithm) is not applicable to this document. The CryOmega is a physical cryosurgical unit, not an AI/software device.
However, I can extract information related to the device's characteristics and the basis for its substantial equivalence.
Here's a breakdown of the requested information based only on the provided text:
1. A table of acceptance criteria and the reported device performance
Since this is a 510(k) for a physical device, the "acceptance criteria" are not framed as statistical performance metrics for an algorithm but rather as characteristics demonstrating substantial equivalence to a predicate device. The "reported device performance" is essentially a comparison of its characteristics to the predicate.
| Characteristic / "Acceptance Criteria" | Predicate Device (Cryoprobe-C K024009) | CryOmega (Reported Device Performance) |

| Service/Repair | Return to Manufacturer. | Disposable once liquefied gas is emptied. No Servicing. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not applicable as the document describes a physical medical device (cryosurgical unit), not a software or AI device requiring a test set of data. The "testing" mentioned refers to engineering and safety verifications, not clinical performance studies with patient data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not applicable. Ground truth for image interpretation or diagnosis is not relevant for this type of device submission.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable.
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
This information is not applicable. This is not an AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
This information is not applicable. The "ground truth" relevant to this submission is the established performance and characteristics of the legally marketed predicate device (Cryoprobe-C) to which the CryOmega is being compared for substantial equivalence.
8. The sample size for the training set
This information is not applicable.
9. How the ground truth for the training set was established
This information is not applicable.

It is believed that the data presented in the Testing Section of this submission is sufficient to demonstrate substantial equivalence between the predicate and CryOmega Device.
Intended Use
The CryOmega is a disposable device intended for the surgical destruction of target tissue by applying cryogenic gases at extreme low temperatures. The list below shows examples of the type of lesions that can be treated.

Technological Characteristics
The CryOmega device is designed to dispense a continuous stream of liquid nitrous oxide when actuated. The device contains a 16g cartridge of nitrous oxide that is dispensed once the device is activated. Physicians or medical professionals can then dispense the gas for use in procedures requiring the destruction of tissue using the extreme cold of nitrous oxide (-89°C). Unlike the predicate device, the CryOmega is designed to be self contained and disposable after all of the liquefied gas has been dispensed. It is believed that this feature increases the safety of the device since operators cannot replace or access the high pressure gas cartridge. Additionally because the device is disposable there is no servicing or maintenance of the CryOmega device.
CONCLUSION
In summary, the CryOmega's path through the 510(k) flowchart ` is as follows:
- The CryOmega has the same intended use as the predicate 피 cryogenic device that is intended for the destruction of tissue using nitrous oxide.
- The CryOmega has the same technological characteristics as . the Cryoprobe-C Device which sprays liquid nitrous oxide gas.
- Both the CryOmega and Predicate using valves to dispense . nitrous oxide gas. Therefore technological differences between the CryOmega and its predicate devices do not raise new questions of safety or efficacy.
- The 510(k) notice includes data and literature to verify that the 다 nitrous oxide in the CryOmega device can safely and effectively cause destruction when used as instructed.
Therefore, STC Consulting believes that FDA can find the CryOmega to be substantially equivalent to the Cryoprobe-C device.
