1. A tissue treatment system, comprising:
- a handpiece having a tissue engaging structure having an apposition surface and a perimeter wall defining a chamber which defines a treatment region in which target tissue may be positioned,the perimeter wall having a conduit defining an opening configured to provide access to the treatment region,a seal disposed within the conduit,a vacuum source configured for application to the tissue engaging structure to elevate the target tissue in the treatment region relative to the surrounding tissue;
a tool configured to be movably coupled to the handpiece through the opening so that a distal end of the tool is positionable in the treatment region for treating target tissue; and
a guidance track operably connectable to the handpiece and the tool,wherein the guidance track is configured to constrain a portion of the tool to move longitudinally and laterally within a predetermined path of the guidance track such that a portion of the tool pivots about the opening and the distal end of the tool moves within a subcutaneous region of the target tissue in a predetermined shape within the treatment region defined by the predetermined path.

Abstract
A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

13. A tissue treatment system, comprising:
-
a handpiece having a tissue engaging structure having an apposition surface and a perimeter wall defining a chamber which defines a treatment region in which target tissue may be positioned, the perimeter wall having a conduit defining an opening configured to provide access to the treatment region, a seal disposed within the conduit, a tool configured to partially pass through the opening such that a distal end thereof is positionable in a subcutaneous region of the target tissue, the engaging structure attached to a vacuum source to elevate the target tissue in the treatment region relative to surrounding tissue; a guidance track operably connectable to the handpiece; and an interfacing structure configured to movably couple the tool to the guidance track, wherein the guidance track defines a predetermined shape and is configured to constrain a portion of the tool to move longitudinally and laterally within a predetermined area of the guidance track such that a portion of the tool pivots about the opening and the distal end of the tool moves within the subcutaneous region of the treatment region within the predetermined shape. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A tissue treatment system, comprising:
-
a handpiece having an apposition surface and a perimeter wall defining a chamber which defines a treatment region for receiving target tissue, the perimeter wall having a conduit defining an opening and configured to provide access to the treatment region, a seal disposed within the conduit, a tool having a distal end positionable through the conduit and into the treatment region, the handpiece being configured to elevate the target tissue in the treatment region relative to surrounding tissue; a first guidance track connectable to the handpiece and defining a first predetermined shape; an interfacing structure configured to movably couple the tool to the first guidance track such that the tool is constrained to move longitudinally and laterally within a predetermined area of the first guidance track whereby a portion of the tool pivots about the opening and the distal end of the tool moves within the first predetermined shape within a subcutaneous region of the target tissue; a second guidance track connectable to the handpiece and defining a second predetermined shape different from the first predetermined shape, the second guidance track having a second predetermined area configured to allow movement of the distal end of the tool within the second predetermined shape. - View Dependent Claims (23, 24, 25, 26, 27)
