Claim Text:
1. A tissue treatment system, comprising: a handle having a housing; an elongate probe extending from the housing and having a distal tip and a flexible length; a liner expandably enclosing the probe; at least one infusion lumen positioned through or along the elongate probe, wherein the infusion lumen defines one or more openings along its length; at least one delivery lumen slidingly positioned through or along the infusion lumen, wherein proximal retraction of the delivery lumen relative to the infusion lumen from a first location increases the number of unobstructed openings, and distal translation of the delivery lumen relative to the infusion lumen from the first location decreases the number of unobstructed openings; and a controller which is programmed to infuse ambient air into the interior of the liner, and wherein the controller is further programmed to infuse a cryoablative fluid or gas into an interior of the liner via the infusion lumen for a period of time of up to 150 seconds such that the cryoablative fluid or gas is sprayed within the liner and into contact upon an interior surface of the liner.
