Description
- This is a continuation-in-part of and claims priority from co-pending U.S. patent application Ser. No. 11/527,332, filed Sep. 25, 2006.
- The present invention relates generally to methods and apparatus for exchanging heat with the spine of a patient.
- It has been discovered that the medical outcome for a patient suffering from various maladies, e.g., severe brain trauma or from ischemia caused by stroke or heart attack or cardiac arrest is improved if the patient is cooled below normal body temperature (37° C.). Furthermore, it is also accepted that for such patients, it is important to prevent hyperthermia (fever) even if it is decided not to induce hypothermia. Moreover, in certain applications such as spinal surgery or to counter the effects of spinal injury, the present invention recognizes that cooling the spine can be advantageous.
- The following U.S. patents, all of which are incorporated herein by reference, disclose various intravascular catheters/systems/methods which, as understood herein, can be used in the novel non-intravascular approach described herein: U.S. Pat. Nos. 6,749,625, 6,419,643, 6,416,533, 6,409,747, 6,405,080, 6,393,320, 6,368,304, 6,338,727, 6,299,599, 6,290,717, 6,287,326, 6,165,207, 6,149,670, 6,146,411, 6,126,684, 6,306,161, 6,264,679, 6,231,594, 6,149,676, 6,149,673, 6,110,168, 5,989,238, 5,879,329, 5,837,003, 6,383,210, 6,379,378, 6,364,899, 6,325,818, 6,312,452, 6,261,312, 6,254,626, 6,251,130, 6,251,129, 6,245,095, 6,238,428, 6,235,048, 6,231,595, 6,224,624, 6,149,677, 6,096,068, 6,042,559, and U.S. patent application Ser.

- SUMMARY OF THE INVENTION A method for treating a patient includes instructing a medical caregiver to advance a closed loop heat exchange catheter into the retroperitoneal space of the patient or into the vasculature of the patient, and to circulate heat exchange fluid through the catheter. The instructions may be given by, e.g., a medical device manufacturer as part of regulatory labeling.
- The catheter may be advanced percutaneously into the patient, and in preferred implementations the heat exchange fluid is colder than the patient. The catheter is closed loop in that heat exchange fluid does not exit the catheter into the patient.
- Preferably, a heat exchange element of the catheter is positioned against the spinal column or in the vena cava. The heat exchange element can be spiral shaped, it can be plastic or metal, and/or it can be a balloon.
- In another aspect, a method for cooling at least a portion of a spinal column of a patient disposed in an operating room includes advancing a closed loop heat exchange catheter into the retroperitoneal space or vasculature of the patient, and circulating heat exchange fluid through the catheter to cool the spinal column. Spinal surgery is then conducted on the patient.
- In another aspect, a method for treating a patient for a hypoxia condition of the spine includes advancing a closed loop heat exchange catheter into the retroperitoneal, space or vasculature of the patient, and circulating heat exchange fluid through the catheter to cool the spinal column and thereby relieve the patient of at least some deleterious effects of spinal hypoxia. The hypoxia condition may be caused by cardiac arrest, myocardial infarction, stroke, or trauma.
- The details of the present invention, both as to its construction and operation, can best be understood in reference to the accompanying drawings, in which like numerals refer to like parts, and which;
-
FIG. 1 is a block diagram of an exemplary patient cooling system; and -
FIG. 2 is a cross-section of a patient, showing the retroperitoneal space and the catheter placed therein. - Referring initially to
FIG. 1 , a patient heat exchange system, is shown and generally designated 10. Thesystem 10 includes an indwellingheat exchange catheter 12 that can be inserted into a patient to heat or cool the patient. Thecatheter 12 may be any of the catheters disclosed in the above-referenced patents or other appropriate closed loop heat exchange catheters. - Coolant such as but not limited to saline is circulated through the
catheter 12 in a closed loop to and from a member such as aheat exchange system 14 through coolant supply andreturn tubes catheter 12 is made of biocompatible material that may be coated with an anti-coagulant substance such as Heperin®. Preferably, thecatheter 12 is made of flexible plastic, and on its distal end it may include one or moreheat exchange elements 13 such as balloons or fibers (including intertwined spiral balloons) or metallic structures. - in the particular non-limiting embodiment shown in
FIG. 1 , thecooling system 14 includes a workingfluid hath container 22 in which a workingfluid bath 24 such as saline, glycol, a mixture thereof, or other appropriate working fluid is disposed. Thecontainer 22 may define acooling receptacle 26 that can receive atubing set 28 through which coolant flows as pan of the closed coolant path. Thetubing set 28 may be implemented as a single length of IV tubing or, as indicated inFIG. 1 , thetubing set 28 may include a serpentine-like coolant path in a bag-like cartridge assembly that can be easily engaged and disengaged with thereceptacle 26. In any case, it will be appreciated that the working fluid in thebath 24 is in thermal contact with thecooling receptacle 26 and, hence, with the coolant in the tubing set 28 to cool the patient coolant flowing through the path when the patient coolant is warmer than the working fluid. - The
cooling system 14 also includes aheat sink 30 that is in thermal contact with the working fluid in thebath 24. The working fluid may be circulated between theheat sink 30 and thebath 24. Theheat sink 30 may be a combined heater/chiller system that can include a refrigerant compressor and/or a thermo-electric cooler (TEC) to cool working fluid.
