摘要： PROBLEM TO BE SOLVED: To provide a central venous line catheter adapted to actively perform heat exchange with a patient's body and can thereby raise or lower the body temperature at need. SOLUTION: A heat exchange element arranged to have a heat exchange relation with the blood of a patient is supplied to the central venous line. The heat exchange element houses in its inside a circulating fluid and the fluid is automatically cooled or warmed outside the patient' body in compliance with the patient's body temperature feedback mechanism.

摘要： A patient control system uses a patient-implanted catheter in thermal communication with a fluid bath via a circulating fluid circuit. A controller automatically controls the temperature of the fluid bath as required for selectively cooling or heating the patient in accordance with patient temperature measurements. The controller thermally decouples the catheter and patient from the fluid bath during changes in fluid bath temperatures in order to overcome the effects of system thermal mass.

摘要： A catheter adapted for heat exchange within a body includes a shaft with at least one input lumen and at least one output lumen in fluid communication with one or more elongate elements which each include a heat transfer lumen. The elongate element is arranged in one or more lengths which include heat transfer lumens being folded into first elongate substantially parallel and juxtaposed portions arranged either in series or parallel or both with adjacent wings. The juxtaposed portions are arranged together in planes extending radially from the center axis of the assembly and are equiangularly placed about that axis. The ends of the portions may be bonded together to create the radial plane. An infusion lumen may extend through the heat transfer assembly with an open end for infusing into the blood stream or sampling therefrom. The efficiency of the heat transfer region is maximized through the elongate thin-walled elements in that surface area is increased and turbulence may be maintained with sufficient input pressure. The employment of the catheter includes its preparation, insertion and expansion with fluid pressure. Additionally, the system may be pressurized to insure turbulent flow through the heat transfer lumens. Use in cardiac surgery and fever control is contemplated with placement of the catheter in the groin, the chest or neck of the patient.

摘要： A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter includes a shaft with a heat exchange region disposed at its distal end. This region may include hollow fibers which are adapted to receive a remotely cooled heat exchange fluid preferably flowing in a direction counter to that of the body fluid. The hollow fibers enhance the surface area of contact, as well as the mixing of both the heat exchange fluid and the body fluid. The catheter can be positioned to produce hypothermia in a selective area of the body or alternatively positioned to systemically cool the entire body system.
