Patent ID: 8900261

Claim:
A tissue treatment system, comprising: a handpiece comprising a recessed tissue engaging chamber defining a treatment region in which target tissue may be positioned, the recessed tissue engaging chamber having a top and being configured to allow elevation of the target tissue into the chamber in the treatment region relative to surrounding tissue; a tissue cutting device movably coupled to a guidance track so that a distal end of the tissue cutting device is positionable into the recessed chamber and in the treatment region for treating tissue, the handpiece further comprising a conduit configured to allow at least a portion of the tissue cutting device to pass into the recessed tissue engaging chamber and defining a pivot point when at least a portion of the tissue cutting device passes through the conduit and into the recessed tissue engaging chamber; the guidance track being configured to operably connect to the handpiece, wherein the guidance track is configured to constrain a portion of the tissue cutting device to move within a predetermined area such that the distal end of the tissue cutting device moves relative to the top within a predetermined shape within the treatment region; and the top having an apposition surface and the target tissue is configured to be elevated into contact with the apposition surface wherein the position of the apposition surface defines a depth of the distal end of the tissue cutting device relative to the apposition surface, wherein the tissue cutting device moves laterally within a plane at the depth from the apposition surface.
