The summary describes a thermal regulation system that uses electro-mechanical components to control temperature. There is no mention of AI, ML, or any data-driven algorithms for decision making or control.
Yes
The device is indicated for use in maintaining normothermia and inducing/maintaining/reversing mild hypothermia in patients, and for fever reduction, all of which are therapeutic interventions.
No
The device is indicated for therapeutic cooling or warming (thermal regulation) in patients and does not provide diagnostic information.
No
The device description explicitly states it is an "integrated electro-mechanical heater/cooler" and includes components like a heat exchanger unit and roller primo, indicating it is a hardware device with software control, not a software-only device.
Based on the provided text, this device is not an In Vitro Diagnostic (IVD). Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The THERMOGARD XP system is described as an "integrated electro-mechanical heater/cooler" that supplies temperature-controlled sterile saline to an indwelling catheter placed in the patient. This is a therapeutic device that directly interacts with the patient's body to regulate temperature.
- Lack of Sample Analysis: There is no mention of the device analyzing samples taken from the patient. Its function is to control the patient's body temperature through the catheter.
Therefore, the THERMOGARD XP is a therapeutic device, not an In Vitro Diagnostic.

Company Confidential
All models of Alsius Intravascular catheters are available for use with the THERMOGARD XP.
Principles of Operation
The THERMOGARD XP system automatically adjusts the temperature of the heater/chiller saline bath to achieve the patient target temperature that has previously been set by the attending physician. This is done via data from a temperature probe in the patient that interfaces with the temperature controller. This principle of operation is identical to the predicate device.
Summary of the Basis for Finding of Substantial Equivalence
The THERMOGARD XP System is substantially equivalent to the Alsius THERMOGARD™ heat exchange system in all its specifications except that its compressor allows additional cooling power.
Conclusion
In summary, descriptive information and performance data demonstrate that the Alsius THERMOGARD XP and Catheter Thermal Regulation System characteristics do not raise new questions of safety and effectiveness. Where appropriate, performance data demonstrate equivalence. The system in this revision acts as its own predicate device. The THERMOGARD XP and Catheter Thermal Regulation System is safe and effective when used in accordance with the Directions For Use and substantially equivalent to the predicate device.

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 (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
