The ZOLL Intravascular Heat Exchange Catheters (Quattro® Intravascular Heat Exchange Catheter Kit, Quattro® Intravascular Heat Exchange Catheter Premium Access Kit, Cool Line® Intravascular Heat Exchange Catheter, ICY® Intravascular Heat Exchange Catheter) are sterile, single use heparin coated flexible catheters designed for placement in the femoral, jugular, or subclavian veins. The

{6}------------------------------------------------

Solex 78 Intravascular Heat Exchange Catheter Premium Access Kit is a sterile, single use 9.3F flexible catheter designed for placement in the superior vena cava from an insection site in the jugular and subclayian veins. The Cool Line catheter contains two heat exchange balloons, the ICY catheter contains three heat exchange balloons, the Quattro catheter contains four heat exchange balloons and the Solex 7® catheter consists of a serpentine balloon. The ZOLL catheters are connected to a single use, disposable Start-Up Kit (SUK), the Coolgard 3000® Console and Thermogard XP® Console. The catheters connect to the console coolant well via tubing integral to the SUK. The catheter is connected to the SUK by connecting the male outflow Luer of the SUK to the female inflow Luer of the catheter and the female inflow Luer of the SUK to the male outflow Luer of the catheter. Both SUK Luers, in turn, are connected via tubing to a heat exchange coil through which saline circulates. The coil is placed in a coolant well located in the console. The controlled temperature saline is circulated through the closed-loop circuit of the SUK and catheter using the console pump, after which the saline is then returned within the SUK to the console heater and chiller coolant well via the catheter's outflow lumen. The catheters, SUK, the Coolgard 3000® Console and the Thermogard XP® Console are supplied separately. The ZOLL Intravascular Heat Exchange System is also designed for use with an off-the-shelf temperature probe, which is supplied separately and not manufactured by ZOLL.
