    摘要: The present disclosure is directed to the use of a cryoprotective agent to protect healthy tissue while damaged tissue is cryosurgically treated. A cryoprotective agent can be delivered utilizing a delivery probe that is inserted into healthy tissue either prior to or during a freeze portion of a first freeze/thaw cycle. The cryoprotective agent diffuses through the healthy tissue, but diffusion is controlled at the freeze edge by the diffusion limiting characteristics of the tissue that is frozen. When the frozen tissue is thawed, the disrupted tissue will continue to restrict the diffusion of the cryoprotective agent. Additional freeze/thaw cycles can then be conducted and the cryoprotective agent will continue to protect the healthy tissue. The delivery probes can also function as thermal sensor probes that can also be used to monitor the temperature at selected tissue locations.

    摘要: 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.

    摘要: Improved imaging and monitoring systems for use with a closed loop cryosurgical system. As described herein, various systems can be used alone or in conjunction with one another to plan and/or monitor cryosurgical procedures in order to improve cryosurgical outcomes. These systems can include computer assisted planning systems, non-ultrasound based imaging systems and temperature monitoring systems utilized individually or in combination. Through the use of these systems, the precision by which cryosurgical procedures are performed are enhanced.

    摘要: 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.

    摘要: An improved closed loop cryosurgical system and related methods of use. The closed loop cryosurgical system can utilize a reduced size cryoprobe by moving a pre-cool heat exchanger into a control console for the system. The cyroprobe can further include a sheath having at least one thermal wire spaced around the sheath that can be heated using the control console so as to thaw frozen tissue. By incorporating thermal wiring into the sheath, the time necessary for a cryosurgical procedure can be significantly reduced, especially where multiple freeze-thaw cycles are conducted. In another aspect, an improved, environmentally friendly mixed gas refrigerant can be provided for use in cooling the cyroprobes. The mixed gas refrigerant avoids the use of the refrigerant R22 while also providing faster and more efficient ice ball formation at the cryoprobe tip, therefore allowing the cryosurgical treatment to be accomplished in less time.
