First Claim
Patent Images
1. A method for heating or cooling at least a selected portion of a body, comprising:
- inserting a catheter into the colon, the catheter including a supply lumen and a return lumen;
conducting a heated or chilled fluid through the supply lumen of the catheter; and
evacuating the fluid from the catheter through the return lumen, wherein the fluid is conducted into the supply lumen by a working fluid source including a temperature control system.

Abstract
A method and apparatus is provided for heating or cooling at least a selected portion of a patient'"'"'s body. The method begins by inserting a catheter having a balloon into the colon or stomach of the patient. A heated or chilled fluid is conducted through a supply lumen of the catheter and into the balloon. The fluid is evacuated from the balloon through a return lumen of the catheter.

4. A method for heating or cooling at least a selected portion of a body, said method comprising:
-
irrigating a balloon inserted into the colon with a heated or chilled fluid;
controlling at least one measurable parameter of the fluid irrigating the balloon;
evacuating the fluid from the balloon; and
monitoring, during the irrigation step, the at least one measurable parameter of fluid flowing out of the balloon, wherein irrigating the balloon includes the step of irrigating the balloon with a flow of fluid. - View Dependent Claims (5, 6, 7, 8, 9)

11. An apparatus for heating or cooling at least a selected portion of a body, comprising:
-
a catheter for irrigating and evacuating a balloon for insertion into the colon with a heated or chilled fluid;
means, coupled to the catheter, for controlling at least one measurable parameter of the fluid irrigating the balloon; and
means for monitoring at least one parameter selected from the group consisting of;
the at least one measurable parameter of fluid flowing out of the balloon while it is being irrigated and a core temperature of the body, wherein the at least one measurable parameter is the temperature of the fluid flowing into and out of the balloon. - View Dependent Claims (12, 13, 14, 15)
