  • Publication number: 20080027419
    Abstract: A probe for use in a cryosurgical system has an integral device for delivering a treatment agent. A representative delivery device can take on a variety of forms, including a lumen located in an outer retractable sheath surrounding the cryoprobe tip, a channel attached to the side of the cryoprobe tip, a channel inside the cryoprobe tip, or a capsule located at the distal end of the cryoprobe tip. The delivery device is sealed to prevent air from being introduced into the system and is provided with a puncture member to break the seal and release the treatment agent as desired by a medical professional.

  • Publication number: 20050177147
    Abstract: A cryoablation system including a cannula having a proximal end, a distal end, and a longitudinal axis, an expandable balloon extending from the distal end of the cannula and fluidly connected to a source of heat transfer fluid by at least one fluid path, a pump for circulating the heat transfer fluid into and out of the balloon, a probe handle coupled to the proximal end of the cannula and in fluidic communication with the balloon through the cannula, and a heat exchanger for varying the temperature of the heat transfer fluid, wherein the heat exchanger is fluidly connected to a secondary refrigerant source. The heat exchanger may be positioned within the probe handle, within the cannula, or at least partially within the balloon. The heat transfer fluid of this cryoablation system preferably has a freezing point lower than about ?110° C. and a boiling point greater than about 50° C.

  • Publication number: 20050177148
    Abstract: A cryoablation system for performing endometrial ablation comprising an elongated tubular cannula having a proximal end, a distal end, and a longitudinal axis, an expandable balloon extending from the distal end of the cannula and fluidly connected to a source of heat transfer fluid by at least one fluid path, a pump for circulating the heat transfer fluid into and out of the balloon, a probe handle coupled to the proximal end of the cannula and in fluidic communication with the balloon through the cannula, and a heat exchanger for varying the temperature of the heat transfer fluid, wherein the heat exchanger is fluidly connected to a secondary refrigerant source, and wherein the heat exchanger comprises an outer tubular wall and a plurality of fins extending from the tubular wall toward the interior portion of the heat exchanger.

  • Publication number: 20040211193
    Abstract: A system including (i) a primary loop including a first oil compressor configured to raise the pressure of a refrigerant flowing through the primary loop, an oil separator configured to separate oil contaminant from the refrigerant, a valve configured to return the separated oil back to the first oil compressor, at least one heat exchanger, and a first expansion element; and (ii) a secondary loop including a primary/secondary heat exchanger, the primary/secondary heat exchanger also forming a part of the primary loop; wherein the refrigerant includes constituents (a) that function as a solvent of the oil contaminant which fail to be separated from the refrigerant and (b) that at least substantially condense in the primary/secondary heat exchanger.
