Abstract

A kit of parts comprises a system and instructions for use for controlling patient temperature which uses a heat exchange catheter having a heat exchange element. The heat exchange catheter is provided with one or more lumens for providing access to the central blood supply of the patient, and with additional lumens for communicating heat exchange fluid to the heat exchange element. Heat exchange fluid temperature is controlled through a feed back loop in which patient temperature is sensed and used to control a temperature control unit comprising a heating device and/or a cooling device in heat exchange relationship with the heat exchange fluid. A tubing set transports the heat exchange fluid between the central venous line and the temperature control unit, with a pump serving to circulate the fluid in a closed fluid circuit in the system.

Claims

1. A kit comprising:

a heat exchange catheter configured for circulating coolant therethrough in a closed loop such that coolant does not enter a patient'"'"'s bloodstream when the catheter is placed in the bloodstream; and

at least one substrate bearing instructions for using the catheter to induce therapeutic hypothermia in a patient having or recovering from at least one of the following maladies;

myocardial infarction (MI), acute MI, cardiac arrest, and stroke.

2. The kit of claim 1, wherein the heat exchange element comprises an array of hollow fibers adapted to transport a heat exchange fluid.

3. The kit of claim 1, wherein the heat exchange element comprises at least one balloon adapted to contain a heat exchange fluid.

4. The kit of claim 3, wherein the catheter defines inlet and outlet lumens for respectively delivering the heat exchange fluid to and from the balloon.

5. The kit of claim 1, wherein the catheter includes at least one anchoring device for holding a portion of the catheter onto the skin of a patient.

6. The kit of claim 1, wherein the catheter is configured for being introduced into a patient percutaneously.

7. The kit of claim 1, wherein the catheter defines at least one infusion lumen for infusing fluid into a patient.
