Device Description

The Focused Cryotherapy System is a cryoablation platform that contains the following components:

Probe (FC-2021CD01)
Console (FC-AR401)
Software

The Focused Cryotherapy System is a cryoablation platform for use in the cryoablation of nerves and tumors. The Probe is a handheld, single use, cryosurgical instrument. The Probe utilizes a high-pressure cryogen (argon gas) to freeze target tissues, creating an inflammatory response, and ultimately, cryonecrosis. In use with tumors, temperatures below -40°C is the temperature at which intracellular ice formation occurs which is lethal for cells. When applied to nerves, temperatures below -20°C cause extracellular ice formation along axonal tubes which causes cessation of action potential conduction. When high pressure argon gas is supplied to the Probe via the Console, rapid cooling is achieved via the Joule-Thomson effect. The Probe incorporates a heating element to facilitate directional cryoablation. The Console has combination gas/electrical ports to handle 4 Probes in parallel. The Console contains the Firmware and Software. The System consists of a main chassis (Console) for the cooling system, Firmware, Software, controls, touch screen and Probe ports. Safety measures of the system include audible and visual alarms, safety valves, and emergency shutoff button.

7. Performance Data (Non-Clinical Testing):

Verification and validation testing was conducted in accordance with applicable international standards and internal requirements to ensure safety, effectiveness, and compliance.

Verification testing included the following:

System Verification: Confirmed proper functionality of Probes, Console, and Software
Mechanical Testing: Evaluated gas components, Probe integrity, and packaging durability
Electrical Safety & EMC Testing: Conducted per IEC 60601-1 and IEC 60601-1-2 standards
Software Verification & Validation: Developed per IEC 62304 and FDA software guidance, verified all software requirements
Biocompatibility Testing: Conducted per ISO 10993 series

Validation testing included the following:

Human Factors Testing: Assessed usability per IEC 60601-1-6, IEC 62366 and FDA human factors guidance
Sterilization Validation: Ensured compliance with ISO 11135 and related standards.
Ex-Vivo Tissue Testing: Testing was performed in porcine tissue samples to validate device tissue effects and quantify thermal performance and temperature-time histories.
Isotherm Comparative Testing: Head-to-head comparison testing was performed with the predicate device to demonstrate substantially equivalent isothermal contours.

All performance tests met predefined acceptance criteria, demonstrating that the Focused Cryotherapy System is as safe and effective as the predicate device. No new risks to safety or effectiveness were identified. No animal or clinical studies were included in this submission.

8. Determination of Substantial Equivalence to the Predicate Device:

Page 12

A subset of technological characteristics and features of the subject device differs from the predicate device. However, these differences do not raise different questions of safety and effectiveness when compared to the predicate devices. Performance data demonstrate that the subject device is as safe and effective as the predicate devices for the same intended use, thereby supporting a determination of substantial equivalence. The subject device has the same intended use as the predicate devices.

9. Conclusion:

The assessment following the outcomes observed in the performance testing and design verification and design validation determines that the Focused Cryotherapy System conforms to the defined user needs and intended uses in both circumferential and directional ablation modes. Focused Cryo, therefore, considers the Focused Cryotherapy System to be safe and effective and to perform at least as well as the predicate devices.
