Abstract
Apparatus and method for providing hypothermia or effecting hemostasis to prevent hemorrhaging in organs or regions of the human body and the like. In one application described herein, the apparatus provides hypothermia to the heart during, for example, cardio-pulmonary bypass. The apparatus comprises a unitary preferably disposable coolant fluid circuit, including a length of flexible tubing having a heat exchange portion and a flexible, inflatable bag through which a sterile coolant fluid passes. The inflatable bag is connected to the flexible tubing by a double lumen. The tubing is provided with appropriate fittings proximate to its juncture with the double lumen to allow introduction of coolant fluid. The heat exchanger portion of the coolant fluid circuit is located within a preferably disposable container which contains refrigeration means for reducing the temperature of the coolant fluid. A pump is provided which operates externally to the coolant fluid circuit in order to cause the coolant fluid to circulate therethrough. Just prior to locating the bag into proximity with the organ to be treated, the fluid circuit is filled with coolant fluid by parting the tubing at the fitting (which may comprise a three-way petcock) and introducing the coolant fluid with the bag maintained in a deflated condition. The bag is then appropriately located proximate to or within the organ, the tubing joined and the bag distended by introducing additional coolant fluid through the fitting using a syringe of the like.
