  • Publication number: 20080125764
    Abstract: A cryosurgical system providing for temperature control of individual cryoprobes so as to simplify and increase treatment flexibility in cryoablation procedures. The cryosurgical system provides individual control of multiple cryoprobes in a closed-loop refrigeration circuit. The individual control allows the simultaneous use of multiple cryoprobes in a procedure. Typically six to eight probes are used but additional probes and control thereof is contemplated by this invention. The primary refrigeration circuit's compressor can also be utilized to generate pressurized hot vapor for heating the probe ends. In order to direct the pressurized hot vapor to the probe ends, an internal valving and control system reverses the direction of pressurized gas flow through the cryoprobes, delivering the hot gas immediately to the ends by bypassing the heat exchangers. Thus each cryoprobe can be independently controllable to provide full, partial or no freezing or heating at any time.

  • Publication number: 20080119833
    Abstract: The present disclosure is directed to a cryoprobe including heating capabilities within the cryoprobe tip for use in a cryosurgical system. A heating element can be operably secured to an inner surface of the cryoprobe tips, wherein the heating element can then be connected to an electrical current source such that heat is generated at the cryoprobe tip as the electrical current flows through the heating element. In one version, the heating element can comprise a resistive element laminated between layers of insulation while in other, alternative versions, the heating element can comprise a small diameter resistance wire attached directly to an inner surface within the cryoprobe tip. The cryoprobe can include a thermocouple secured within the cryoprobe tip so as to take temperature measurements during both freezing and thawing cycles. In some versions, the heating element can be operably secured within the cryoprobe tip using an expanding or rotating mandrel.

  • Publication number: 20080115509
    Abstract: Methods and apparatus for connecting disposable and non-disposable portions of a cryoprobe for use with a cryosurgical treatment system. Representative cryoprobes can include a disposable and non-disposable portion joined with a connector such as a coupler for connecting a single disposable portion to a single non-disposable portion. A representative coupler can include coupler ports into which connecting ends of fluid delivery tubes within the disposable and non-disposable portions can fluidly connect. A manifold mounting plate can include a plurality of slots into which disposable portions can be fluidly interconnected to non-disposable portions.
