1. A method of treating tissue, comprising:
- engaging a first portion of tissue with a handpiece having a recessed chamber;
applying a vacuum force to move a target portion of tissue into the recessed chamber which defines a treatment region of the handpiece so that the target portion is elevated relative to surrounding tissue;
inserting a tool into the treatment region through a conduit opening of the recessed chamber so that a distal end of the tool penetrates the target portion of tissue and enters a subcutaneous region of the target portion of the tissue;
coupling the tool to a guidance track connected to the handpiece; and
moving the tool longitudinally and laterally along the guidance track so that a portion of the tool pivots about the conduit opening and so that the distal end of the tool is moved within a region of predetermined shape within the target portion of tissue defined by the longitudinal and lateral movement of the tool;
wherein the tool treats the target portion of tissue by severing septae at a first depth below the surface of the dermis.

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.

12. A method of treating dermal tissue, comprising:
-
cutting septae in a predetermined shape in subcutaneous tissue by; capturing a target portion of tissue with a handpiece having a recessed chamber; applying a vacuum to the handpiece and elevating the target portion of tissue relative to surrounding tissue and into the recessed chamber; coupling a guidance track to the handpiece; and manipulating an interventional tool longitudinally and laterally along the guidance track such that a portion of the interventional tool pivots about an opening of a conduit in the recessed chamber, such that a distal end of the interventional tool cuts the septae, wherein the interventional tool is coupled to the guidance track which constrains the interventional tool to move the distal end in response to the longitudinal and lateral motion of the interventional tool along the guidance track. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of treating cellulite, comprising:
-
engaging a first portion of tissue comprising epidermis, dermis and subcutaneous tissue with a handpiece having a chamber; applying a vacuum to draw a target portion of tissue into the chamber of the handpiece so that the target portion of tissue is elevated relative to surrounding tissue; inserting a tool through an opening of a conduit in the chamber into the chamber such that a distal end of the tool penetrates the target portion of tissue and extends within the subcutaneous tissue; coupling the tool to a guidance track connected to the handpiece; and moving the tool longitudinally and laterally along the guidance track such that a portion of the tool pivots about the opening and the distal end of the tool is moved within a region of predetermined shape within the target portion of tissue that is defined by the movement of the tool along the guidance track; wherein the tool severs septae in the target portion of tissue at a first depth below the surface of the dermis. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
