US Patent:

6648906, Nov 18, 2003

Filed:

Apr 5, 2001

Appl. No.:

09/827010

Inventors:

Juan C. Lasheras - La Jolla CA
Steven A. Yon - San Diego CA
Michael Magers - Encinitas CA

Assignee:

Innercool Therapies, Inc. - San Diego CA

International Classification:

A61F 700

US Classification:

607105, 607104, 604 27

Abstract:

A method and apparatus is provided for heating or cooling at least a selected portion of a patients 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.

Filed:

Feb 25, 2002

Appl. No.:

10/082964

Inventors:

Michael Magers - Encinitas CA
Steven A. Yon - San Diego CA

Assignee:

Innercool Therapies, Inc. - San Diego CA

International Classification:

A61F 700

US Classification:

607105, 607106

Abstract:

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.

Appl. No.:

10/216487

Inventors:

Michael Magers - Encinitas CA

Assignee:

Innercool Therspies, Inc. - San Diego CO

International Classification:

A61F 700

US Classification:

607105, 607106

Abstract:

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 patients 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.

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 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.

Assignee:

Innercool Therapies, Inc. - San Diego CA

International Classification:

A61F007/00

US Classification:

606105, 607113

Abstract:

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.
