  • Cryo-surgical apparatus and method of use
    Patent number: 7422583
    Abstract: Cryosurgical apparatus includes an elongate cryoprobe having a cooling portion and an electrically conductive first portion in the region of the cooling portion. A removable sheath having an electrically conductive second portion is received on the cryoprobe with its electrically conductive second portion spaced from the electrically conductive first portion of the cryoprobe. Electrical insulation is interposed between the first portion and the second portion. Coolant material supplied to the cryoprobe produces tissue freezing in the region of the cooling portion. Electromagnetic energy supplied to either the first portion or the second portion, while the other of such first portion or second portion is connected to ground, provides selective heating in tissue surrounding an iceball produced by the cooling portion to control the configuration of the iceball.
    Type: Grant

  • Cryo-surgical apparatus and methods
    Patent number: 7393350
    Abstract: Cryosurgical apparatus includes an elongate cryoprobe having an electrically conductive first portion and multiple cooling elements. A removable sheath having an electrically conductive second portion is received on the cryoprobe with its electrically conductive second portion spaced from the electrically conductive first portion of the cryoprobe. Electrical insulation is interposed between the first portion and the second portion. In operation, cooling elements in the cryoprobe cool the tissue around a portion of the cryoprobe while electromagnetic energy traveling between the first portion and the second portion heats tissue adjacent to the cooled tissue. The cooling alters the path of the electromagnetic energy by changing the electrical conductivity of the tissue in the region of the cryoprobe.
