  • Patent number: 12256971
    Abstract: Liners for cryogenic treatment systems are described where a cryogenic fluid or gas may be introduced into a liner expanded within a body lumen such as the uterine cavity. The liner may be intentionally sized to be substantially larger than the typical size of the uterine cavity, e.g., 1.2 times (or more), greater than the size of the uterine cavity into which the liner is inserted. Because the liner is sized intentionally larger than the body lumen to be treated, the liner may never fully expand when deployed. But even with folds or portions of the liner being folded upon itself, the liner may remain sufficiently supple such that the resulting uncontrolled folds allow for complete conformance of the liner against the anatomy of the contacted tissue.

  • Patent number: 12150688
    Abstract: An exhaust collection bag for cryogenic treatment is described herein and may generally comprise a first layer and a second layer attached along a periphery and forming an enclosed volume. The periphery defines four radiused corners and an extension member. A tubing connector may be positioned along the first layer and extend through the first layer and may also be located along a centerline of the first layer and in proximity to a bottom edge of the first layer. A drain closure may also be positioned along the first layer and located away from the centerline and in proximity to the bottom edge.

  • Patent number: 11957398
    Abstract: Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure sensing elements which may allow for control of the pressure within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled or room temperature fluid such as water may then be used to rapidly terminate the treatment session.

  • Publication number: 20240016533
    Abstract: Apparatus and methods for regulating cryogenic treatments are disclosed which comprise devices and methods for delivering controlled treatment of a cryoablative agent. In one variation, such devices may generally comprise an elongate probe having a distal tip and a flexible length, at least one infusion lumen positioned through or along the elongate probe, wherein the infusion lumen defines one or more openings along its length, and a liner expandably enclosing the probe. An inflow reservoir or canister valve may be fluidly coupled with a reservoir or canister containing the cryoablative agent and a modulation control unit may also be fluidly coupled with the inflow reservoir or canister valve and in fluid communication with the at least one infusion lumen. Additionally, a warming element may also be thermally coupled with the reservoir or canister.

The liner may be intentionally sized to be substantially larger than the typical size of the uterine cavity, e.g., 1.2 times (or more), greater than the size of the uterine cavity into which the liner is inserted. Because the liner is sized intentionally larger than the body lumen to be treated, the liner may never fully expand when deployed. But even with folds or portions of the liner being folded upon itself, the liner may remain sufficiently supple such that the resulting uncontrolled folds allow for complete conformance of the liner against the anatomy of the contacted tissue.

  • Publication number: 20230078672
    Abstract: Exhaust removal apparatus and methods for cryogenic treatment are described herein. The apparatus may generally include a housing having an inlet for fluidly coupling to a source of water and an outlet for fluidly coupling to a drain, and a suction chamber in fluid communication with the housing, wherein the suction chamber is further configured to be detachably coupled to an exhaust collection reservoir having a volume of exhaust gas. Introduction of water through the inlet generates a pressure reduction within the suction chamber such that the volume of exhaust gas is drawn from the exhaust collection reservoir and into the housing for dissolving into the water and out through the drain.

  • Publication number: 20220249173
    Abstract: A treatment system for treating tissue is disclosed in which a handle with an elongate shaft projecting from the handle, a sheath axially slidable relative to the elongate shaft, and an electrode mounted on a proximal portion of the sheath is provided. A substrate having an elongate portion may be located within the handle. A plurality of first and second capacitive sensors may be positioned along the elongate portion. The electrode may be configured to slide along the elongate portion during movement of the sheath. The electrode may maintain contact with at least one of the first capacitive sensors at least one of the second capacitive sensors during movement of the sheath. The substrate may be configured to determine an axial position of the electrode based on a coupling capacitance caused by an electrode overlapping one or more of the first capacitive sensors and one or more of the second capacitive sensors.
