No
The device description focuses on hardware components (control unit, cryoprobe, CPLD) and physical principles (Joule-Thompson). There is no mention of software algorithms, data processing for decision-making, or any terms related to AI/ML. The control is described as being managed by a CPLD and direct console keys, not through complex data analysis or learning.
Yes.
The device is used for the "ablation" of various tissues, including malignant and benign tumors, which indicates a therapeutic purpose to treat disease or conditions.
No
Explanation: The device is described as a "Treatment System" designed to "destroy tissue by the application of extreme cold temperatures" (ablation), which is a therapeutic function, not a diagnostic one. While it monitors temperature, this is for controlling the treatment, not for diagnosing a condition.
No
The device description clearly outlines hardware components including a control unit, cryoprobe, thermocouples, LED screen, and keys on the console. It is a physical system that utilizes software for control, but it is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, to provide information for diagnostic, monitoring or compatibility purposes.
- Device Function: The description clearly states the device is a "Visica Treatment System" designed to "destroy tissue by the application of extreme cold temperatures" (cryoablation). It is a therapeutic device used directly on the patient's body.
- Intended Use: The intended uses listed are all therapeutic procedures (ablation of fibroadenoma, lesions, neoplasia, tumors) or localization of lesions, performed directly on the patient.
- No Specimen Examination: There is no mention of the device being used to examine specimens derived from the human body.
Therefore, the Visica Treatment System is a therapeutic device, not an In Vitro Diagnostic device.

Device Description
The Visica Treatment System consists of a control unit that controls one single-use, disposable (Visica Treatment Device or "cryoprobe"). The system utilizes incrt argon gas as a cooling agent and helium for thawing. The cystem unit operates from standard 120/240 VAC wall power and is control by a CPLD (Complex Programmable Logic Device). An LED screen displays the status of the system. System control is accomplished directly through keys on the console itself.
The cryoprobe operates on the Joule-Thompson principle and the refrigerative capacity is limited only the distal tip of the probe. The cryoprobe incorporates a thermocouple to measure temperature near the probe tip. The thermocouple is mounted inside the cryoprobe tip and its signal is used to monitor and control some operations of the system. The control unit can also accommodate two independent on the ts manitant to monitor temperatures in the surrounding tissues. The temperature probes use standard T-type needle thermocouples.

Dear Ms. Depel:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
