    摘要: 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.

    摘要: A method and apparatus for lowering the body temperature of a patient while reducing shivering by using a heat exchange device in combination with an α2-adrenoreceptor agonist, a non-opiod analgesic monoamine uptake inhibitor or neuropeptide that temporarily reduces shivering. The devices disclosed include a catheter having a heat exchange balloon thereon with heat exchange fluid circulating through the interior of the balloon. The heat exchange balloon is placed in the vasculature of a patient, and heat exchange fluid at a temperature other than the temperature of the blood in the vasculature is circulated through the interior of the balloon to add or remove heat from the blood of the patient. Various α2-adrenoreceptor agonistα2-adrenoreceptor agonists, non-opiod analgesic monoamine uptake inhibitors and neuropeptides are disclosed including dexmedetomidine, nefopam, neurotensin and anticonvulsant medications and pharmaceutically acceptable salts thereof. A control system for the control of the patient's temperature is disclosed for controlling the patient's temperature in conjunction with administering the α2-adrenoreceptor agonist, non-opiod analgesic monoamine uptake inhibitor or neuropeptide.

    摘要: The heat exchange catheters comprise a catheter body having a heat exchange structure formed over a distal region thereof. Heat exchange structure comprises an elastic chamber or balloon which conforms closely to the catheter body when uninflated and which expands to enhance the available heat transfer surface when heat exchange medium is introduced. The elastic structures may consist of elastomeric sheets or membranes or may comprise non-distensible sheets or membranes having elastic elements in order to control expansion and contraction. Methods for fabrication and use are also disclosed.

    摘要: Methods and apparatus for preventing myocardial infarction, or lessening the size/severity of an evolving myocardial infarction, by cooling at least the affected area of the myocardium using an intravascular heat exchange catheter. The heat exchange catheter may be inserted into the vasculature (e.g., a vein) and advanced to a position wherein a heat exchanger on the catheter is located in or near the heart (e.g., within the vena cava near the patient's heart). Thereafter, the heat exchange catheter is used to cool the myocardium (or the entire body of the patient) to a temperature that effectively lessens the metabolic rate and/or oxygen consumption of the ischemic myocardial cells or otherwise protects the ischemic myocardium from undergoing irreversible damage or infarction.
