1. A tissue treatment system, comprising:
a handle;
an elongate lumen extending from the handle;
at least one infusion lumen positioned through or along the elongate lumen;
at least one delivery lumen in fluid communication with the infusion lumen, wherein the delivery lumen defines one or more openings for infusing a cryoablative agent;
a liner defining an interior in which the elongate lumen is positionable;
a sheath translatable relative to the elongate lumen;
an exhaust lumen in fluid communication with the interior of the liner; and
a valve positioned within the exhaust lumen, wherein the valve is configured to control a pressure of the cryoablative agent within the system.
