Embodiments of the invention provide a system for temperature control of the human body. The system includes an indwelling catheter with a tip-mounted heat transfer element. The catheter is fluidically coupled to a console that provides a heated or cooled heat transfer working fluid to exchange heat with the heat transfer element, thereby heating or cooling blood. The heated or cooled blood then heats or cools the patient's body or a selected portion thereof. In particular, strategies for optimizing the rewarming of patients for various medical procedures are provided, including stroke, neurosurgery, and myocardial infarction.

A therapeutic pad system comprises an ice patch having a generally disc-shaped configuration. The ice patch has a circular generally parallel first and second walls fabricated of a plastic-vinyl material. A non-solid gel which is capable of being frozen, thawed and re-frozen a plurality of times is located within the space between the walls. A jacket is fabricated of a cloth material and has a generally disc shaped configuration with an interior panel and an exterior panel and a pocket there between for receiving the ice patch. Common stitching is over approximately the lower two-thirds of the jacket and the upper one-third forms an opening. Decorative indicia coupled to the exterior panel of the jacket.

A shape-retaining bag having a front and a back connected to each other to define a chamber between for housing and retaining a fill material within a plurality of cells within the chamber which are made of a plurality of walls and one or more flow diverters adjacent to the cells and on the ends of the walls. A passageway is on a fill-side with a second passageway on an opposing side, each passageway extending approximately from one end side to another end side of the bag. As fill material is introduced into the chamber, it passes through the cells and the passageways in a fashion dictated by the cells and by the flow diverters until the bag is filled. The configuration of the various cells and flow diverters permit the bag to retain its shape notwithstanding the fill material within.

Systems, apparatus, and methods for treating spinal tissue and other body structures in open and endoscopic spine surgery to relieve symptoms, such as neck or back pain. In particular, the present invention provides methods for the controlled heating of various tissues in or around the vertebral column, including various interspinous tissues, such that spinal ligaments and cartilage surrounding the vertebrae and the facet joints are shrunk or tightened to stabilize the vertebral column of a patient. Thermal energy is applied to the target tissue in a subablation mode of an electrosurgical system to cause shrinkage of the tissue, thereby stiffening the interspinous tissue and stabilizing the vertebral column. In an exemplary embodiment, a high frequency RF voltage can be applied between one or more active electrode(s) and one or more return electrode(s) to heat a target interspinous tissue to within a temperature range at which irreversible shrinkage of the tissue occurs.

Cooling pads, mattresses, and limb-conforming sleeves reduce a person's temperature by evaporative and/or conductive cooling. An open cell foam pad defines an internal air flow passages proceeding according to serpentine or other desired routing. The pad is wetted, and a blower circulates air through the air flow passage and evaporatively cools the pad by removing warm water vapor. By contacting the cooled structure, the person is conductively cooled. The pad also employs evaporative cooling if water is permitted to seep from the foam pad onto the person's skin and subsequently evaporate. Another cooling device is a multi-layer evaporative cooling mattress. The mattress comprises an open cell foam structure having a person-receiving side and a base side. At the person-receiving side lies an absorbent layer with internal liquid delivery lines, and optionally having an outer film applied thereto. Beneath the absorbent layer is an air manifold comprising air flow passages defined in a cushion layer, or an open mesh layer interposed between the absorbent layer and cushion layer. Another cooling device is a thermal cooling sleeve, with a series of multiple elongated, parallel ridges. Pairs of adjacent ridges are separated by intervening channels, and each ridge has a lateral liquid passage through it. When the first and last ridges are brought around to meet each other, the ridges form a contiguous sleeve. Within the sleeve's body, the passages cooperatively define a continuous conduit proceeding from ridge to ridge inside the sleeve.

A cancer thermotherapy apparatus of the present invention has an ortho-hexahedral cavity resonator and a loop antenna on a upper inner wall surface of the cavity resonator. The loop antenna is attached so that its loop face can be parallel to two side inner wall surfaces which are opposed each other, and orthogonal and adjacent to the upper inner wall surface. A high frequency electric power introduced into the cavity resonator is resonated in the parallel direction to the side wall surfaces on an excited mode with a constant electric field intensity along the side wall surfaces. A human body is set in the direction parallel to the side inner wall surfaces in the cavity resonator, and the resonated high frequency electric power is applied to the human body.

The invention relates generally to methods of treating cancer and other diseases by modulating body temperature. Heat may directed to the hypothalamus of a warm-blooded animal to cool the animal, utilizing the physiological mechanisms that regulate body temperature to effect a compensatory cooling response, thereby lowering body temperature (hypothermia), and rendering other methods of lowering body temperature more effective. Heat may be withdrawn from the hypothalamus of an animal, cooling the hypothalamus, inducing a compensatory increase in body temperature (hyperthermia), and rendering other methods of raising body temperature more effective. Body temperature may be directly modulated by heat-exchange catheter positioned within a blood vessel of a patient. The invention relates generally to methods of treating cancer by inducing hypothermia by directing heat to the hypothalamus, optionally maintaining cancerous tissue at or near to normal body temperature, and optionally applying another cancer treatment. This other cancer treatment may be radiation therapy, chemotherapy, a combination of radiation and chemotherapy, or some other cancer treatment. The invention relates generally to methods of treating diseases including cancer, viral infections, and other diseases, comprising inducing hyperthermia by cooling the hypothalamus, and optionally applying another treatment, for example radiation, chemotherapy, antiviral therapy, or a combination of therapies.

Disclosed is an apparatus and method for preventing secondary ischemic injury in the brain. The apparatus includes an interstitial brain-cooling probe that is placed into an ischemic region of the brain by stereotaxic surgical technique, and a control console. The control console provides a source of cooling fluid to the interstitial brain-cooling probe, and controls the flow of cooling fluid according to signals received from a temperature sensor mounted on the interstitial brain-cooling probe. The interstitial brain-cooling probe cools an ischemic region of the brain from within the ischemic region, and cooling is substantially limited to the ischemic region. Cooling is provided for a period of time greater than one hour.
