No
The device description and intended use focus on a mechanical cryotherapy device for dispensing liquid nitrogen, with no mention of AI/ML components or functions.
Yes
The device is used for "freeze destruction on epithelial arising cryoresponsive benign, premalignant and malignant tumors," which is a therapeutic procedure.
No
The device description and intended use clearly state that it is used for "freeze destruction on epithelial arising cryoresponsive benign, premalignant and malignant tumors" and for "dispensing of liquid nitrogen." This indicates a therapeutic or treatment function, not a diagnostic one.
No
The device description clearly outlines physical components made of stainless steel, brass, and teflon, 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 is for the freeze destruction of various skin lesions. This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is a cryosurgical tool designed to dispense liquid nitrogen for freezing tissue.
- Lack of IVD Characteristics: An IVD device is used to examine specimens (like blood, urine, or tissue samples) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not perform any such analysis of specimens.
The device is a therapeutic device used for a medical procedure, not a diagnostic test performed on samples.

Dear Ms. Grafelman:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls.
