No
The description focuses on the electro-mechanical components and the physical mechanism of temperature regulation through a closed-loop saline system. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
Explanation: The device is indicated for "fever reduction, as an adjunct to other antipyretic therapy," which is a direct therapeutic action.
No
The device is described as an integrated electro-mechanical heater/cooler system for thermal regulation, specifically for fever reduction. Its intended use is therapeutic (fever reduction), not diagnostic (identifying or characterizing a disease or condition).
No
The device description clearly outlines multiple hardware components including an integrated electro-mechanical heater/cooler, disposable start-up kit, and intravascular catheters. It is a system with significant hardware elements.
Based on the provided text, the Alsius CoolGard® 3000 and Cool Line ™ Catheter Thermal Regulation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is for "fever reduction... in patients with cerebral infarction and intracerebral hemorrhage who require access to the central venous circulation and who are intubated and sedated." This describes a therapeutic intervention performed directly on the patient's body, not a test performed on a sample taken from the body.
- Device Description: The device description details a system that circulates temperature-controlled saline through a catheter placed in the central venous circulation to exchange heat with the patient's blood. This is a physical process for temperature regulation within the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The system's function is to directly modify the patient's body temperature.
Therefore, this device falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

Intended Use / Indications for Use
The Alsius CoolGard® 3000 and Cool Line ™ Catheter Thermal Regulation System is indicated for use in fever reduction, as an adjunct to other antipyretic therapy, in patients with cerebral infarction and intracerebral hemorrhage who require access to the central venous circulation and who are intubated and sedated.

Device Description
The CoolGard and Catheter Thermal Regulation System consists of the CoolGard™ 3000, a disposable Start Up Kit used in the CoolGard™ for interface with the cooling bath and patient catheter and the Intravascular Catheter. The Alsius CoolGard™ 3000 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 essentially identical to those of widely used multi-lumen central venous catheters except for the dedicated closed loop fluid path through the heat exchange balloons. The Alsius Catheter materials are all biocompatible polyurethanes. Likewise, the CoolGard™ 3000 heater/cooler has the same technical features as the medical heater/cooler unit Identified as the predicate device. These common technical features include connections for recirculating coolant to and intravascular catheter and all or combinations of the following: redundant safety controls and alarms, patient monitoring and control and temperature displays for the clinician users. Two Models of Intravascular catheters are available for use with the CoolGard and Catheter Thermal Regulation System: - 1. Cool Line™ Catheter Kit Model CL 2085B (2 lumens) - 2. Cool Line™ Catheter Kit Model CL 2295A (3 lumens) The Cool Line™ catheters are multi lumen intravascular catheters in two sizes. Two of the catheter's lumens are used to circulate sterile saline to exchange heat with the central venous blood supply. When the heat exchange feature of the catheter is in use, heated/chilled saline is pumped through the heat exchange lumen, expanding the diameter of the distal portion of the catheter to a nominal 5mm where the heating/cooling membranes interface with the patient's circulating blood. The inflow lumen/outflow lumen forms a closed-loop system through which the heated/chilled saline circulates. The chilled saline is not infused into the patient. Additional lumens of the Alsius Catheters consist of a standard quide wire lumen that can be used as a primary infusion lumen, and a second or third infusion lumen within the shaft, depending on the catheter model selected by the clinician. The Catheter blood contact surfaces are coated with Duraflo® Treatment, a heparin coating manufactured by Edwards Lifesciences Corporation. The Alsius Catheters are supplied sterile for single-use only.

Technical Characteristics:
The CoolGard and Catheter Thermal Regulation System consists of the CoolGard™ 3000, a disposable Start Up Kit used in the CoolGard™ for interface with the cooling bath and patient catheter and the Intravascular Catheter. The Alsius CoolGard™ 3000 is an integrated electro-mechanical heater/cooler that consists of a temperature monitor, a temperature controller unit, a heat exchanger unit, and roller pump.

The technical characteristics of the Catheter are essentially identical to those of widely used multi-lumen central venous catheters except for the dedicated closed loop fluid path through the heat exchange balloons. The Alsius Catheter materials are all biocompatible polyurethanes.
Likewise, the CoolGard™ 3000 heater/cooler has the same technical features as the medical heater/cooler unit Identified as the predicate device. These common technical features include connections for recirculating coolant to and intravascular catheter and all or combinations of the following: redundant safety controls and alarms, patient monitoring and control and temperature displays for the clinician users.
Two Models of Intravascular catheters are available for use with the CoolGard and Catheter Thermal Regulation System:
-
- Cool Line™ Catheter Kit Model CL 2085B (2 lumens)
-
- Cool Line™ Catheter Kit Model CL 2295A (3 lumens)
The Cool Line™ catheters are multi lumen intravascular catheters in two sizes. Two of the catheter's lumens are used to circulate sterile saline to exchange heat with the central venous blood supply. When the heat exchange feature of the catheter is in use, heated/chilled saline is pumped through the heat exchange lumen, expanding the diameter of the distal portion of the catheter to a nominal 5mm where the heating/cooling membranes interface with the patient's circulating blood. The inflow lumen/outflow lumen forms a closed-loop system through which the heated/chilled saline circulates. The chilled saline is not infused into the patient.

The Catheter blood contact surfaces are coated with Duraflo® Treatment, a heparin coating manufactured by Edwards Lifesciences Corporation.
The Alsius Catheters are supplied sterile for single-use only.
Principles of Operation:
The CoolGard™ 3000 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 currently marketed devices.
Summary of the Basis for Finding of Substantial Equivalence:
The Cool Line™ indication statements and intended use are identical to those for central venous catheters and heater/cooler units. The Cool Line™ catheter provides access to the central circulation for fluid administration. Additionally, the closed loop connections on the catheter can be attached to the heater/cooler unit for patient heating or cooling via conductive heat transfer from the temperature controlled saline. The Cool Line™ integrates venous access and temperature control which, separately, are intended uses for numerous devices.
The integration of temperature control and venous access could potentially affect safety and effectiveness in new ways that would raise new types of safety or effectiveness questions. Accepted scientific methods were used to generate performance data demonstrating the substantial equivalence of the Cool Line™ Catheters and CoolGard™ System to the predicate. In addition, the clinical study under IDE G990263 was conducted to further define safety characteristics.
Conclusion
In summary, descriptive information and performance data demonstrate that the Alsius Cool Line™ Catheter and CoolGard™ System's different technological characteristics either do not raise new questions of safety and effectiveness or, where appropriate, performance data demonstrate equivalence.
