Spinal stabilization devices and their methods of insertion and use to treat degenerated lumbar, thoracic or cervical spinal discs in minimally invasive, outpatient procedures are described. In one embodiment, the spinal stabilization device is an expandable cage made of a coil or perforated cylindrical tube with a bulbous or bullet-shaped distal end and a flat or rounded proximal end. In a preferred embodiment, the spinal stabilization device is mechanically expanded to a larger diameter or is made of a superelastic nickel-titanium alloy which is thermally programmed to expand to a relatively larger diameter when a pre-determined transition temperature below body temperature is reached. To treat a degenerated disc, a guide wire is inserted into the disc and an endoscope is inserted through a posterolateral puncture in the back and advanced up to the facet of the spine. Mechanical tools or laser energy, under endoscopic visualization, are used to remove or vaporize a portion of the facet bone, creating an opening into the foraminal space in the spine for insertion of an endoscope, which enables the disc, vertebra and nerves to be seen. The passageway is expanded, mechanical tools or laser of RF energy are used to make a tunnel into the disc, and a delivery cannula is inserted up to the opening of the tunnel. An insertion tool is used to insert one or more spinal stabilization devices into the tunnel in the disc, preserving the mobility of the spine, while maintaining the proper space between the vertebra. Laser or radio frequency (RF) energy is used to coagulate bleeding, vaporize or remove debris and shrink the annulus of the disc to close, at least partially, the tunnel made in the disc.

The invention relates generally to methods and apparatus for inducing hypothermia in an animal. Known methods for inducing hypothermia all involve cooling the outside or inside of an animal, sometimes in conjuction with drugs that disable the animal's homeostatic responses. The present invention is directed to a method and apparatus for applying heat to the hypothalamus of a warm-blooded animal in order to utilize the physiological mechanisms that regulate body temperature to effect a compensatory cooling response, thereby lowering body temperature. It is new and unsuggested in the art to apply heat in an effort to reduce body temperature. The invention effects the desired lowering of body temperature by the method od raising the temperature of the hypothalamus, a brain structure situated in humans just above the pituitary gland responsible for temperature regulation, by warming a nasal passage, or a sinus, such as the sphenoid sinus that is nearest to the hypothalamus, or by direct warming of the hypothalamus, or a combination of these.

The Ice Belt To Reduce Body Temperature is a belt made of a turned out strip of flexible material of amble width and length to gird the waist from the midriff down, contains pocket-like receptacles on its innermost body-contacting side for the placement of flexible ice bags, and is secured around the waist by a connecting means. The Ice Belt to Reduce Body Temperature is a new concept of belts intended for sports, exercise and safety because the Ice Belt To Reduce Body Temperature provides the wearer with the comfort of a lower body temperature when exposed to high climatic conditions. In fact, most belts pertaining to the prior art are designed to promote sweating—a symptom of high body temperature—rather than reduce sweating. Therefore, the Ice Belt helps to lessen the risk of the user acquiring heat exhaustion when exposed to high climatic conditions.

Body temperature measurements are obtained by scanning a thermal radiation sensor across the side of the forehead over the temporal artery. A peak temperature measurement is processed to compute an internal temperature of the body as a function of ambient temperature and the sensed surface temperature. The function includes a weighted difference of surface temperature and ambient temperature, the weighting being varied with target temperature through a minimum in the range of 96° F. and 100° F. The radiation sensor views the target surface through an emissivity compensating cup which is spaced from the skin by a circular lip of low thermal conductivity.

A method of determining a temperature of a patient includes measuring a first temperature of the patient with a temperature device without contacting the patient with the device, and measuring a second temperature of the patient by contacting a measurement site of the patient with the device. The method also includes determining a temperature value indicative of a core temperature of the patient based on the first and second temperatures.
