Abstract

Medical devices for inducing hypothermia are disclosed. Induced hypothermia is a treatment used to reduce secondary complications caused by reduced oxygen and blood flow during traumatic injuries and surgeries. However, induced hypothermia also has negative side effects such as shivering and lowered immune system. These devices incorporate Highly-Oriented Pyrolytic Graphite (HOPG) for solid conduction to lower the temperature at targeted locations on and inside the body. The benefits of incorporating HOPG include: highly efficient heat conduction, flexibility in design and manufacture, reduction of dependence on inefficient and unstable fluid-filled implants and catheters, and anti-thrombotic effects.

Claims (6)

1. A device for inducing hypothermia comprised of:

a. a Highly Oriented Pyrolytic Graphite (HOPG) implant comprised of one or more sheets of HOPG folded in an accordion-pattern;

b. an HOPG transmission member in solid thermal conductive connection with the HOPG implant, such that the HOPG transmission member transfers heat to and from the HOPG implant by solid conduction; and

c. an external cooling element for cooling the HOPG transmission member.

2. The device of claim 1 , wherein the external cooling element comprises a cooled liquid or gas.

3. The device of claim 1 , wherein the external cooling element comprises an electronic device.
