  • Patent number: 10687887
    Abstract: A bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The jaws members are connected to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. At least one non-conductive and spaced-apart stop member is disposed on an inner-facing surface of the jaw members to regulate the gap distance between the jaw members when tissue is held therebetween. The forceps also includes a longitudinally reciprocating knife which severs the tissue after sealing at a location which is proximate the sealing site.

  • Patent number: 10653474
    Abstract: A working surface of the electrode head, designed to be essentially hemispherical in shape, is made of a suitable high-temperature-resistant metal. The electrode head is supplied with power via an electrical connecting line. The rear surface of the electrode head forming the sectional surface of the hemisphere is planar and is covered with an insulating cover made of a ceramic material. The transitional region from the working surface to the rear surface does not have an edge but instead is rounded with a minimum radius of curvature, which is substantially greater than one-thirtieth of the width, which corresponds to the hemisphere diameter (=twice the radius of the hemisphere), which is the dimension of the electrode head in the direction of its maximum extent. The relatively large radius of curvature prevents the main activity of the electrode from occurring at its boundary due to excessively high local current densities.

  • Patent number: 10610292
    Abstract: The present disclosure relates to devices, systems and methods providing evaluation and feedback to an operator of a device providing neuromodulation treatment, such as modulation of renal nerves of a human patient. In one embodiment, for example, a system monitors parameters or values generated before treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of various electrical properties associated with an electrode carried by a catheter. The electrode measures an electrical property of biological material making contact with the electrode while deploying the electrode, the electrical property being dependent on a ratio of a wall-interface area to a fluid-interface area.

    Abstract: A method of cancer hyperthermia therapy includes placing a device including an exogenously-excitable polymeric material at a cancer hyperthermia therapy site of a patient. The method also includes supplying an exogenous energy to the device such that the exogenous energy excites the exogenously-excitable polymeric material at the cancer hyperthermia therapy site to heat the cancer hyperthermia therapy site to a hyperthermia temperature. A method of preparing a polymeric material includes combining an alcohol monomer, a seed of the polymeric material, and an aqueous liquid in a vessel. The method also includes adding an acid monomer to the vessel and supplying an exogenous energy to the vessel. The polymeric material is exogenously excited by the exogenous energy to heat the polymeric material. The method further includes removing water from the vessel and producing the polymeric material, which is a polyester, in the vessel.
