Patent number: 12256971Abstract: 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.Type: GrantFiled: February 10, 2023Date of Patent: March 25, 2025Assignee: Channel Medsystems, Inc.Inventors: Daniel R. Burnett, William Malecki

Patent number: 11957398Abstract: 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.Type: GrantFiled: November 3, 2020Date of Patent: April 16, 2024Assignee: Channel Medsystems, Inc.Inventor: Daniel R.

Publication number: 20230078672Abstract: 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.Type: ApplicationFiled: November 16, 2022Publication date: March 16, 2023Applicant: Channel Medsystems, Inc.Inventors: William MALECKI, Vincent LOPRESTI, Ulric E.
