The description focuses on the mechanical and software control of cryogen delivery and system functions, with no mention of AI or ML algorithms for decision-making, image analysis, or predictive capabilities.
Yes
The device is described as a "cryosurgical tool for the destruction of unwanted tissue" in various medical fields, which falls under the definition of a therapeutic intervention.
No
The device is described as a "cryosurgical tool for the destruction of unwanted tissue," focusing on treatment rather than diagnosis.
No
The device description clearly outlines multiple hardware components including a console, touch panel computer, cryogen/suction/electronics modules, foot pedal, wireless remote control, fill kit, and disposable spray kit with catheters and decompression tubes. While software is mentioned as managing functions, it is integral to and controls the operation of this hardware system.
Based on the provided information, the truFreeze® System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the system is a "cryosurgical tool for the destruction of unwanted tissue." This describes a therapeutic procedure performed directly on the patient's body.
- Device Description: The description details a system that applies liquid nitrogen to tissue for ablation. This is a physical intervention, not a test performed on samples outside the body.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing diagnostic information based on sample analysis
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The truFreeze® System performs a surgical procedure, not a diagnostic test.

Intended Use / Indications for Use
The truFreeze® System is intended for use as a cryosurgical tool for the destruction of unwanted tissue in the fields of dermatology, gynecology, and general surgery.

Device Description
The truFreeze® System is a cryosurgical tool that applies medical-grade liquid nitrogen to the ablation area via a small, low pressure, open tipped catheter. The truFreeze System consists of (1) a console and (2) a disposable spray kit.
The console is the central interface of the system and is comprised of a touch panel computer (TPC) and cryogen, suction and electronics modules packaged in a mobile cart. Users interact with the console through a dual foot pedal and the touch panel. A controller and associated software manage the cryogen level sensing, filling, pressure, cooling, defrost, suction, timing and data management functions. A wireless remote control provides alternative timer control from a distance in the procedure room. A fill kit, stored on the rear of the console, allows for liquid nitrogen transfer from the source tank to the console. Safety features include indicators, tank pressure relief valves, an isolated low voltage power system, and an emergency shut-off button.
The truFreeze spray kit consists of sterile single-use catheters and cryogen decompression tubes (CDTs). The catheter is flexible and capable of retroflex in a scope. The CDT and accessory tubes are included for use with the on-board suction system.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The truFreeze System was subjected to a comprehensive test program to evaluate conformance to product specifications and demonstrate substantial equivalence to the predicate device(s). Electrical safety and electromagnetic compatibility testing, software testing, biocompatibility and sterilization testing were conducted in accordance with applicable standards. In addition to the design verification and validation testing, user validations using animal models were also conducted. Test results demonstrated that the truFreeze System meets its specifications and does not raise any new safety and/or effectiveness issues.
