Abstract: A tethered system for cryogenic treatment is disclosed in which a hand piece having an elongate probe with a distal tip and a flexible length, at least one infusion lumen positioned through or along the elongate probe, and a liner may be tethered to a base station having a reservoir of a cryoablative fluid via a connection having an elongate flexible body. The connection defines at least one fluid lumen for delivery of the cryoablative fluid from the reservoir and to the infusion lumen within the hand piece.

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.

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.

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 and temperature sensing elements which may allow for control of the pressure and temperature 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, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.
