Alsius CoolGard 3000
No
The document mentions software revisions but provides no indication of AI/ML technology being incorporated. The performance study focuses on clinical outcomes (mortality) and does not describe AI/ML model performance metrics.
Yes
The device is indicated for medical purposes such as achieving/maintaining normothermia in cardiac surgery patients, inducing/maintaining/reversing mild hypothermia in neurosurgery patients, and reducing fever in patients with cerebral infarction and intracerebral hemorrhage. These are all therapeutic applications.
No
The Intended Use / Indications for Use section clearly states that the device is "indicated for use: - In cardiac surgery patients to achieve and or maintain normothermia during surgery and recovery/intensive care, and - To induce, maintain and reverse mild hypothermia in neurosurgery patients in surgery and recovery/intensive care." It also mentions "fever reduction, as an adjunct to other antipyretic therapy". These are all therapeutic uses, not diagnostic.
No
The device description explicitly states that the THERMOGARD is an "integrated electro-mechanical heater/cooler" consisting of hardware components like a temperature monitor, controller unit, heat exchanger, and roller pump. While software revisions are mentioned, the device is fundamentally a hardware system with software control.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The THERMOGARD and Catheter Thermal Regulation System is designed to directly control the patient's body temperature (normothermia or mild hypothermia) by circulating temperature-controlled saline through an intravascular catheter placed within the patient's central venous circulation.
- Intended Use: The intended uses described are related to managing body temperature in patients undergoing surgery or in intensive care, and for fever reduction. These are therapeutic or supportive interventions, not diagnostic tests performed on specimens outside the body.
The device is a therapeutic medical device used for temperature management within the patient's body, not for analyzing samples in a laboratory setting.
N/A
Intended Use / Indications for Use
The THERMOGARD can be used with any of the Alsius Catheters. The indications for use are specific to the catheter. Please refer to the Indications for Use statement in the catheter specific Instructions for Use.

Technical Characteristics
The THERMOGARD and Catheter Thermal Regulation System consists of the THERMOGARD, a disposable Start Up Kit used to interface between the cooling bath of the THERMOGARD and the intravascular Catheter. The THERMOGARD is an integrated electro-mechanical heater/cooler that consists of a temperature monitor, a temperature controller unit, a heat exchanger unit, and roller pump. It supplies temperature controlled sterile saline to the indwelling Catheter that is placed percutaneously in the patient.
The technical characteristics of the Catheter are identical to the predicate device with the exception of revisions to the software that controls the device.
All models of Alsius Intravascular catheters are available for use with the THERMOGARD.

Principles of Operation
106 3829
The THERMOGARD 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 System is substantially equivalent to the Alsius CoolGard 3000™ heat exchange system in all its specifications.
Conclusion
In summary, descriptive information and performance data demonstrate that the Alsius THERMOGARD 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 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.

Dear Dr. Collins:
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.
The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the device's labeling as a box warning immediately following the indications for use statement:
The safety of this device has not been demonstrated for fever reduction in patients presenting with subarachnoid hemorrhage or primary traumatic brain injury. The safety and effectiveness of this device was examined in a randomized controlled trial of 296 patients. The mortality results reported in this trial, for the four patient cohorts enrolled, are presented in the table below (CI -- cerebral infarction, ICH -- intracerebral hemorrhage, PTBI - primary traumatic brain injury, SAH - subarachnoid hemorrhage).

*Fischer's exact test
For more details on the results of this study please refer to "Physician's Manual – Fever Reduction for Patients with Cerebral Infarction and Intracerebral Hemorrhage" #101416-001.
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification if the limitation statement described above is added to your labeling.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
If you desire specific information about the application of other labeling requirements to your device (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" (21 CFR Part 807.97).
