Apparatus for implementing hyperthermia
First Claim
1. An apparatus for implementing hyperthermia comprising:
- at least one catheter for creating a fluid external to an animal or patient for which hyperthermia is indicated;
a pump in fluid communication with said at least one catheter, wherein said pump pumps fluid at approximately 2400 ml. per minute;
a heat exchanger through which said fluid circuit flows, said heat exchanger having a fluid reservoir for maintaining fluid in the reservoir at approximately 52°
C.;
at least one each of a pressure sensor, temperature sensor, and alarm; and
a computer and user interface means, adapted to receive signals from the pressure sensor and temperature sensor, for regulating a desured patient temperature, wherein said apparatus is capable of establishing the desired patient temperature in as little as twenty minutes.

Abstract
An apparatus and system for extracorporeal treatment utilizes a hemodialysis machine capable of heating dialysis fluid to 48° C., an optional parallel plate hemodialyzer together with a sorbent-based detoxifier, a tubular heat exchanger and a high flow pump—in addition to various probes and catheters—to effect extracorporeal treatment without adverse physiological effect and without the specific need for general anesthesia. The system inheres in the combined high flow of the pump-up to 2400 ml per minute—and the high temperature—52° C.—achievable in the heat exchanger, which together provide unprecedented speed and efficiency in the administration of hyperthemia treatments. The system is also a potentiating system in the administration of heat sensitive pharmaceutically active agents and is praticularly useful in the isolated anatomic areas of a patient.

6. An apparatus for implementing hyperthermia in a subject comprising:
-
a first fluid circuit including;
a supply of a first fluid; and
a heater for heating a flow of the first fluid to an elevated temperature, wherein said heater establishes the elevated temperature of approximately 52°
C.;
a second fluid circuit including;
an inlet for a flow of a second fluid having a temperature which is lower than the elevate temperature of the first fluid, said inlet being adapted to be placed in fluid communication with the subject;
a pump for pumping the second fluid at a flow rate of substantially 2400 ml per minute; and
an outlet for the flow of the second fluid, said outlet being adapted to be placed in fluid communication with the subject;
a heat exchanger in fluid communication with each of the first and second fluid circuits for placing the flow of the first fluid in heat exchange relationship with the flow of the second fluid in order to raise the temperature of the second fluid for delivery to the subject; and
a control system for regulating the first and second fluid circuit in order to establish a desired treatment temperature for the patient. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
