  • Patent number: 8679110
    Abstract: A catheter includes a plurality of primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes an electrode located at the working end of the catheter. Separation is maintained between the primary leads such that each primary lead can individually receive power of selected polarity. The primary leads are constructed to expand outwardly to place the electrodes into apposition with an anatomical structure. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure. The diameter of the hollow anatomical structure is reduced by the heating effect, and the electrodes of the primary leads are moved closer to one another. Where the hollow anatomical structure is a vein, energy is applied until the diameter of the vein is reduced to the point where the vein is occluded. In one embodiment, a secondary lead is surrounded by the primary leads, and extends beyond the primary leads.

  • Patent number: 8515554
    Abstract: A radiometric heating/sensing probe for radiating electromagnetic waves of a first frequency capable of heating tissue and detecting electromagnetic waves of a second frequency emitted by the tissue indicating tissue temperature. The probe includes a dual frequency antenna, a signal transmitting path to the antenna and a signal receiving path from the antenna to a radiometer. A diplexer connected between those paths inside the probe includes a quarter wave stub in the form of a shorted slab line-type transmission line in the signal transmitting path. The entire probe package is only about 0.4 in. long and 0.08 in. in diameter so that it can be used in many minimally invasive applications.

  • Patent number: 8353906
    Abstract: A method and apparatus for dehydrating, electro-oxidizing, or electro-reducing a target tissue is described. The apparatus utilizes an electrochemical probe or other device to deliver one or more beneficial agents into the target tissue. Water from the target tissue provides a precursor that may be split by electrolysis to generate the beneficial agent. Alternatively, water is provided from an external source to generate the beneficial agent. The beneficial agent facilitates in situ oxidation and/or reduction of a material within the tissue. One type of beneficial agent is ozone.

  • 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: 8007525
    Abstract: The present invention provides a method and apparatus for controlling the internal body temperature of a patient. According to the present invention, a catheter is inserted through an incision into a large blood vessel of a patient. By selectively heating or cooling a portion of the catheter lying within the blood vessel, heat may be transferred to or from blood flowing within the vessel and the patient's body temperature may thereby be increased or decreased as desired. The invention will find use in treating undesirable conditions of hypothermia and hyperthermia, or for inducing a condition of artificial hypothermia when desired.

  • Patent number: 7993337
    Abstract: A circumferential ablation device assembly which is adapted to forming a circumferential conduction block in a pulmonary vein is described. The assembly includes a circumferential oblation clement which is adapted to ablate a circumferential region of tissue along a pulmonary vein wall which circumscribes the pulmonary vein lumen, thereby transecting the electrical conductivity of the pulmonary vein against conduction along its longitudinal axis and into the left atrium. The circumferential ablation element includes an expandable member with a working length that is adjustable from a radially collapsed position to a radially expanded position. An equatorial band circumscribes the outer surface of the working length and is adapted to ablate tissue adjacent thereto when actuated by an ablation actuator. A pattern of insulators may be included over an ablation element which otherwise spans the working length in order to form the equatorial band described.

  • Patent number: 7981147
    Abstract: A method of treating meibomian gland dysfunction. Heat is applied to the outside of the eyelid to provide conductive heat transfer to the meibomian glands. The application of heat assists in the expression of obstructions or occlusions in the meibomian glands to restore sufficient sebum flow to the lipid layer to treat dry eye. A force may also be applied to the outside of the patient's eyelid to improve conductive heat transfer and reduce blood flow in the eyelid that causes convective heat loss. Thus, the application of force can further increase the temperature level and/or reduce the time to reach desired temperature levels for removing obstructions or occlusions. Reaching increased temperature levels may improve the melting, loosening, or softening of obstructions or occlusions in the meibomian glands while reducing the amount of time to reach desired temperature levels and/or aid in reducing discomfort to the patient during treatment.

  • Patent number: 7976543
    Abstract: Methods and apparatus employed in surgery involving making precise incisions in vessels of the body, particularly cardiac blood vessels in coronary revascularization procedures conducted on the stopped or beating heart are disclosed. Such incisions are created by applying an elongated electrosurgical cutting electrode to the outer surface of the vessel wall in substantially parallel alignment with the body vessel axis, the elongated electrosurgical cutting electrode having a predetermined cutting electrode length exceeding the cutting electrode width. RF energy is applied between the electrosurgical cutting electrode and the ground electrode at an energy level and for a duration sufficient to cut an elongated slit through the vessel wall where the elongated electrosurgical cutting electrode is applied to the surface of the vessel wall.
