The CryoGun® liquid nitrogen cryosurgical system
Not Found
No
The device description and intended use focus on a cryosurgical system using liquid nitrogen, with no mention of AI or ML technologies.
Yes
The device is described as treating various medical conditions like tumors, skin tags, and verrucae, which falls under the definition of a therapeutic device.
No
Explanation: The device is intended for the treatment of various skin conditions, not for diagnosing them. It is a cryosurgical tool that dispenses liquid nitrogen for destructive therapy.
No
The device description clearly outlines physical components like a stainless steel flask, valves, nozzles, and probes, indicating it is a hardware device for dispensing liquid nitrogen.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used for the treatment of various skin conditions and tumors. IVDs are used for the diagnosis of diseases or conditions by examining samples from the human body (like blood, urine, tissue).
- Device Description: The device description details a system for dispensing liquid nitrogen for cryosurgery. This is a therapeutic procedure, not a diagnostic test.
- Lack of IVD Characteristics: The description does not mention any components or processes related to analyzing biological samples, which is a core function of IVDs.
Therefore, the CryoPro® Mini and CryoPro Maxi units are therapeutic devices used for cryosurgery, not in vitro diagnostic devices.
N/A
Intended Use / Indications for Use
The CryoPro® Mini and CryoPro® Maxi units are intended to be used within the fields of dermatology and plastic surgery for the treatment of cryoresponsive benign, premalignant and malignant tumors such as skin tags, verrucae, actinic keratoses and basal cell carcinoma.

Device Description
The CryoPro® Mini consists of a 0.35 L stainless steel vacuum insulated, stainless steel flask equipped with a stainless steel top which holds a pressure relief valve and a dispensing valve for dispensing liquid nitrogen. The dispensing valve body is made of stainless steel with a brass valve stem and sealed with a Teflon gasket.
The dispensing valve may be mounted with spray nozzles or closed contact probes of varying sizes depending on the size and nature of the area to be treated.
The CryoPro® Maxi provides a 0.5 L stainless steel vacuum insulated flask and is otherwise identical to the CryoPro® Mini unit.

Trade Name of Device Submitted: CryoPro® Mini and CryoPro® Maxi
Common Name: Cryosurgical Unit and Accessories
Classification Name: Cryosurgical Unit and Accessories (21 C.F.R. § 878.4350)
Predicate Device: The CryoPro® Mini and CryoPro® Maxi cryosurgical units are substantially equivalent to the CryoGun® liquid nitrogen cryosurgical system manufactured by Brymill Corporation. To the best of Cortex's knowledge, the CryoGun® is a "pre-amendments" device.
Device Description: The CryoPro® Mini consists of a 0.35 L stainless steel vacuum insulated, stainless steel flask equipped with a stainless steel top which holds a pressure relief valve and a dispensing valve for dispensing liquid nitrogen. The dispensing valve body is made of stainless steel with a brass valve stem and sealed with a Teflon gasket.
The dispensing valve may be mounted with spray nozzles or closed contact probes of varying sizes depending on the size and nature of the area to be treated.
The CryoPro® Maxi provides a 0.5 L stainless steel vacuum insulated flask and is otherwise identical to the CryoPro® Mini unit.
Intended Use: The CryoPro® Mini and CryoPro® Maxi units are intended to be used within the fields of dermatology and plastic surgery for the treatment of cryoresponsive benign, premalignant and malignant tumors such as skin tags, verrucae, actinic keratoses and basal cell carcinoma.
Technological Characteristics and Similarities: The CryoPro® Mini and CryoPro® Maxi units are similar in intended use, design, materials and construction to the Brymill CryoGun® units. The vacuum insulated flask is similar in design and holds the same working pressure. The relief valve, the dispensing valve, spray nozzles and contact probes are also similar in intended use, materials and construction.
