Embodiments of the invention provide a system for temperature control of the human body. The system includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient's body or a selected portion thereof. In particular, strategies for optimizing the rewarming of patients for various medical procedures are provided, including stroke, neurosurgery, and myocardial infarction.

Method and device for patient temperature control employing optimized rewarming

Methods and apparatus are provided for heating or cooling a patient's whole body or a selected portion of a patient's body. In one embodiment, the method begins by inserting a catheter having a dual balloon system into the large intestine of a patient. A heated or chilled liquid is conducted through a supply tube of the catheter and into the inner balloon. The liquid is evacuated from the inner balloon through a return lumen of the catheter. The outer balloon conducts heat transfer between the patient's tissues and the inner balloon, and further provides a degree of safety against rupture of the inner balloon.

Embodiments of the invention provide a system for temperature control of the human body. The system includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient's body or a selected portion thereof. In particular, methods and devices, including software, are provided for administering cooling or rewarming and controlling the same based on a projected control temperature measured by a temperature sensor within the catheter.

System and method for patient temperature control employing temperature projection algorithm

A system and method for temperature control of the human body includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient's body or a selected portion thereof. Cooling is provided while monitoring an EEG signal of a patient, and employing the same to monitor a depth of hypothermia of the patient.

Method and apparatus for patient temperature control employing titration of therapy using EEG signals

A device and method for providing body cooling for treating fever. The cooling device applies cooling to blood flowing in a vein or artery, e.g., the vena cavae, that is then distributed throughout the body.

Fever regulation method and apparatus

System and method for inducing hypothermia with active patient temperature control employing catheter-mounted temperature sensor and temperature projection algorithm

A fluid level detector system, which may measure the amount of fluid in a reservoir, and may further trigger an alarm when the fluid level in the cassette reaches a low level condition. The cassette's reservoir may contain a transient sterile solution, which is moving through the cassette to be either cooled or heated in the heat exchanger area. The detection scheme includes a ring magnet housed in a float assembly located in the fluid reservoir of the cassette and, e.g., two magnetic sensors, such as may form a Hall effect integrated circuit, which may be fixed within the console.

Low fluid level detector system

A method and apparatus is provided for determining an effective thermal mass of a patient. The effective thermal mass is employed to determine a gain factor used in a feedback control system controlling patient temperature. The method begins by inducing hypothermia or hyperthermia in at least a selected portion of the patient with a device having a heat transfer surface. Next, power is transferred between the device and the patient. A change in temperature over time, which arises in the selected portion of the patient, is measured while performing the step of inducing hypothermia or hyperthermia. Finally, an effective thermal mass is calculated based on the measured power and the measured temperature change over time.

Method for determining the effective thermal mass of a body or organ using a cooling catheter

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 through the urethra and into the bladder of the patient. A heated or chilled fluid is conducted through a supply lumen of the catheter and into the bladder. The fluid is evacuated from the bladder through a return lumen of the catheter. Finally, a quantity of urine is monitored which flows out of the bladder and through the return lumen of the catheter. The rate of fluid flowing through the supply lumen of the catheter may be adjusted in a manner that is based at least in part on the monitored quantity of urine flowing out of the bladder.
