  • Patent number: 8007496
    Abstract: A method of treating a tissue region (e.g., a tumor) is provided. The method comprises introducing a delivery sheath within an anatomical conduit that supplies the tissue region with a fluid (e.g., blood or air). The anatomical conduit may be any naturally occurring conduit within a patient. The method further comprises expanding an occlusive device (e.g., a balloon) associated with the delivery sheath, such that the conduit is at least partially occluded to reduce the flow of fluid through the conduit. The method further comprises introducing a tissue treatment catheter within the delivery sheath, advancing the treatment catheter from the delivery sheath through an aperture in a wall of the conduit adjacent the tissue region, and conveying thermal energy from (i.e., hyperthermia) or to the treatment catheter (i.e., hypothermia) to treat (e.g., by ablating) the tissue region.

  • Patent number: 7959658
    Abstract: A medical, electrically powered thermal cover for fitting predominantly the trunk and head of a person experiencing or potentially experiencing traumatic or cold-exposure hypothermia. The thermal cover encases all of the torso and neck, and portions of other body areas. Heating may be distinctly non-uniform, being applied to the body surface only in special regions where the body's capacity for heat uptake may be relatively high. In sum, the system may monitor deep body core temperature, direct heat to the body core where it may be most needed, and controls therapy over time to restore normothermia.

  • Patent number: 7871427
    Abstract: A system and method for portably delivering a therapeutic dose of heat to the skin to relieve pain, reduce accommodation of thermal nerve receptors, promote healing, and deliver transcutaneous medications. The heating device is user programmable or pre-programmed to deliver according to a variety of cycles, patterns and algorithms. The cycles, patterns, and algorithms of the heat are programmable parameters, are under the user's control, and increase the effectiveness and efficiency of the device. The heating algorithms are designed to interact with an individual user's thermal nerve receptors and other tissue characteristics and to reduce the tendency of the receptors to accommodate to the external stimuli with back pain, muscular pain, dysmenorrhea, headaches, fibromyalgia, post-herpetic neuralgia, nerve injuries and neuropathies, and sprains and strain.
