No
The description focuses on the physical mechanism of cryotherapy and temperature monitoring, with no mention of AI or ML algorithms for data analysis, decision-making, or control beyond simple temperature thresholds.
Yes
The device is described as being used for "temporary reduction of pain, swelling, inflammation, and hematoma" and as "an adjunct to rehabilitative treatment," which are therapeutic applications.
No
The device is a cryotherapy device used for treatment (cold therapy), not for diagnosing conditions. While it monitors skin temperature, this is for controlling the treatment, not for diagnostic purposes.
No
The device description clearly outlines multiple hardware components including a hand-piece, electronic console, battery, CO2 cylinder, and an infrared temperature measurement system.
Based on the provided information, the CRYOTRON 2 ® Cryotherapy Device is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The CRYOTRON 2 ® Cryotherapy Device is a therapeutic device that applies cold therapy directly to the skin surface.
- The intended use clearly describes a therapeutic application: "for use when cold therapy is indicated for the temporary reduction of pain, swelling, inflammation, and hematoma..." This is a treatment, not a diagnostic process.
- The device description details a physical therapy method: applying a cold spray to the skin. There is no mention of analyzing biological samples.
Therefore, the CRYOTRON 2 ® Cryotherapy Device falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The CRYOTRON 2 Cryotherapy Device is for use when cold therapy is indicated for the temporary reduction of pain, swelling, inflammation, and hematoma from minor surgical procedures, minor sprains or other minor sports injuries, and as an adjunct to rehabilitative treatment (e.g., intermittent cold with stretch).

Device Description
The CRYOTRON 2 ® Cryotherapy Device delivers a topical spray of compressed medical-grade carbon dioxide. The patented technology of the CRYOTRON 2 ® Cryotherapy Device uses the natural expansion of liquid CO₂ to create a cold spray of micro- crystals delivered under pressure. Using a gradual sweeping motion, the user applies the spray to the treatment site for 30-60 seconds at a distance of 3-5 inches. Rapid cooling (thermal shock) occurs when the spray sublimates (passes directly from solid (ice) phase to gas phase) as it contacts the skin. The CRYOTRON 2 ® Cryotherapy Device consists of four components that are housed in a mobile cart:
- A pistol-grip hand-piece that delivers the carbon dioxide spray.
- An electronic console/control panel that provides operational information to the user.
- A rechargeable battery.
- A cylinder of compressed medical-grade carbon dioxide gas (sold separately).
An infrared temperature measurement system continuously monitors the temperature of the skin surface. The skin surface temperature is displayed on the electronic console, and a red LED on the pistol-grip hand-piece flashes when the skin surface temperature falls to 4°C. An optional laser pointer within the pistol-grip hand-piece provides a visual indication of the zone where the skin temperature is measured.
