International Classification:

A61F 7/00

US Classification:

607106, 607 96, 607104

Abstract:

Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.

US Classification:

422/045000, 604/006110, 604/006140

Abstract:

Apparatus and methods for pumping and oxygenating blood are provided that include a gas removal system. An integrated blood processing unit is provided in which a gas removal/blood filter, pump and blood oxygenation element are mounted within a common housing. The gas removal system includes a sensor mounted on the housing to sense the presence of gas, and a valve is operably coupled to the sensor to evacuate gas from the system when the sensor detects an accumulation of gas.

US Classification:

422/044000, 604/006090

Abstract:

Apparatus and methods for removing gas from a blood handling system. A filter apparatus for monitoring and removing gas is provided comprising of a gas removal/blood filter, a sensor to sense the presence of gas, and a valve operably coupled to the sensor to evacuate gas from the apparatus when the sensor detects an accumulation of gas. When used with a previously known blood handling system, the present filter apparatus facilitates priming and the addition of additional blood handling elements during operation of the blood handling system.

US Classification:

422/045000, 604/006140

Abstract:

Apparatus for processing blood in an extracorporeal circuit with automatic flow control is provided in which error conditions are sensed and system operation is modulated responsive to the error conditions. The apparatus comprises an extracorporeal blood processing system, at least one sensor to sense the presence of gas or to monitor venous pressure, and a controller operably coupled to the blood processing system to selectively reduce pump speed or reconfigure flow paths the blood processing system responsive to the sensor output.
