Abstract: The present invention relates to an apparatus or making extracorporeal blood circulation available, in particular a heart-lung machine, comprising a venous connection and an arterial connection, between which a blood reservoir, a blood pump and a bubble detector for the detection of air bubbles are provided, with, downstream of the bubble detector, an arterial line leading to the arterial connection via an arterial clamp and a bypass leading via a bypass clamp back into the blood reservoir which is connected to a pump extracting air from the blood reservoir. In addition, the present invention relates to a method of operating such an apparatus.

Abstract: A balloon catheter is used in a closed-loop heat exchange system for manipulating the temperature of a patient. The balloon catheter is positioned in the stomach of the patient, and then expanded with a heat exchange fluid delivered through a lumen formed in the shaft of the catheter. The balloon catheter comes into contact with the wall of the stomach, and the stomach substantially conforms around the expanded balloon catheter. The heat exchange fluid is allowed to flow continuously into and out of the balloon catheter. Heat is exchanged between the balloon catheter and the stomach so as to controllably alter the temperature of at least a portion of the patient. Anti-shivering mechanisms and automatic control based on temperature feedback from the patient may be used in connection with the heat exchange system.

Abstract: A peristaltic pump has an arcuate raceway with a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The arc defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and translationally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A motor is coupled to the rotor to rotate the rotor plural are rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. The motor is prevented from stopping at a predetermined angular position to facilitate loading and unloading tubing.

Abstract: Catheter devices and methods for intravascular heating and/or cooling of human or veterinary patients. The catheter devices generally comprise catheters having inflow and outflow lumens and at least one curvilinear balloon connected to the inflow and outflow lumens such that heat exchange fluid may be circulated through the balloon(s). The catheter is inserted into the vasculature and heated or cooled fluid is circulated through the balloon(s) to heat or cool blood flowing in heat-exchange proximity to the balloon(s), thereby effecting heating or cooling of all or a portion of the patient's body.

Abstract: A cooling system for an indwelling heat exchange catheter includes a heat exchange bath that is configured to receive a conduit that carries saline to and from the catheter. A heating/cooling fluid is in the bath and exchanges heat with the saline. The heating/cooling fluid flows through a heat exchanger that includes a refrigerant and two variable speed DC compressor for removing heat from the refrigerant. A gear pump circulates the working fluid to and from the catheter and is removably engaged with a pump support platform.
