Patent number: 8298221Abstract: A sheath for use with a cryoprobe in a cryosurgical procedure can have an opening at its proximal end configured to be inserted over a tip portion of a cryoprobe. The sheath can be connected to the cryoprobe with an end connector. Sheath can have a tip located at its distal that can have a trocar configuration for tissue penetration. A cylindrical section located inwardly from the tip can have a spiral groove defined on an exterior surface. At least one wire can be disposed within the groove so as to fit within the outer perimeter of the sheath. Wires disposed in grooves can include heating elements and temperature sensing elements. Sheath can further include a graduated catheter located inwardly from the cylindrical section and a handle located inwardly from the graduated catheter.Type: GrantFiled: November 19, 2007Date of Patent: October 30, 2012Assignee: CooperSurgical, Inc.Inventors: David W.

Patent number: 8298220Abstract: The present disclosure is directed to a cryoprobe capable of improving the cooling power of a cryosurgical system. A representative cryoprobe can comprise an inner cooling chamber and a radial chamber, positioned between the inner cooling chamber and an exterior wall of the cryoprobe. Preferably, the radial chamber is formed to have a low thermal conductivity so as to significantly reduce the transfer of heat between the body and the refrigerant in the inner chamber during a cryosurgical procedure. The radial chamber can be fabricated such that a vacuum can be applied to the radial chamber to further reduce heat transfer between the body and the inner cooling chamber. The radial chamber extends partially along the length of the cryoprobe such that inner cooling chamber is in direct thermal contact with the exterior wall at a cryoprobe tip.Type: GrantFiled: November 15, 2007Date of Patent: October 30, 2012Assignee: CooperSurgical, Inc.Inventors: Douglas A. Devens, Jr., David W. Vancelette, Michael W. V. Perkins
