Claim Text:
1. A tissue treatment system, comprising: 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; at least one delivery lumen slidingly positioned through or along the infusion lumen, wherein translation of the delivery lumen relative to the infusion lumen controls a number of unobstructed openings along the infusion lumen such that 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 liner expandably enclosing the probe such that a cryoablative fluid introduced through the unobstructed openings is sprayed into contact with an interior surface of the liner and coats the interior surface.
