    Abstract: An apparatus and method for thermally destroying tumors. A tip has a plurality of deployable thermal conductive elements whose temperatures are individually controllable. This allows the shape of the thermal field to be controlled and for specific areas to be protected from excessive heat by cooling those specific areas while ablating other areas. In another embodiment, the deployable thermal conductive elements are individually deployable to various lengths to further aid in shaping the thermal field. The temperatures and the shape of the thermal field may be monitored and controlled by a data processing device, such as a microprocessor. Further selectivity in defining the area of tissue to be treated may be achieved by introducing into the tissue thermal additives that alter the thermal properties of the tissue.

  • Patent number: 8840609
    Abstract: A jaw heating element of a handpiece of a thermal tissue operating system is tested on an ongoing basis by supplying a test heater power signal to the jaw heating element between individual thermal tissue operations. Voltage and current through the jaw heating element is sensed and the resistance of the jaw heating element is calculated. If the calculated resistance is outside a range of predetermined acceptable values, an error condition is indicated.

  • Publication number: 20140276707
    Abstract: A therapy system for use with a patient and a method of treating a medical condition of a patient. Electrical stimulation energy is delivered to a stimulation site on the wall of a blood vessel, thereby evoking at least one compound action potential in a nerve branch associated with the blood vessel. The evoked compound action potential(s) is sensed at a sensing site on the wall of the blood vessel. A circumferential location of the nerve branch is identified as being adjacent one of the stimulation site and the sensing site based on the sensed compound action potential(s). Ablation energy is delivered to an ablation site on the wall of the blood vessel adjacent the circumferential location of the nerve branch, thereby ablating the nerve branch and treating the medical condition.

  • Patent number: 8753381
    Abstract: An apparatus for determining a thermal property of tissue includes a base unit with one or more energy source and at least two, preferably detachable, leads. The distal end of each lead, which is introduced into the tissue to be treated, has at least two longitudinally spaced temperature measuring elements to measure surrounding tissue temperature and at least two longitudinally spaced electrode surfaces for applying current to the tissue. Each distal end is also provided with an element which uses energy emitted by the sources of energy to heat up the surrounding tissue. The base unit has computing elements, current generating elements for generating an alternating current, and conductance determining elements for determining the tissue conductance between pairs of electrode surfaces based on the alternating current applied by the current generating elements to the tissue. Methods for using the device and leads for use in the device are also described.

    Abstract: A treatment device for a medical treatment heats a biotissue. The device includes a treatment tool which includes a heat transfer portion and a resistance element, a storage section which stores a time-power list including time-power relations, and a controller. The controller includes a resistance value acquiring section acquiring a resistance value of the resistance element, a power supplying section supplying the power to the resistance element, and a control section. The control section causes the power supplying section to supply a predetermined state detection power in a state detection period, calculates a change of the resistance value in the state detection period, acquires the time-power relation corresponding to the change of the resistance value, and causes the power supplying section to supply the power based on the acquired time-power relation.
