Abstract:
1. A method of dissecting tissue below a surface of a dermis of a patient, comprising: engaging a first portion of the dermis with a handpiece; applying a force to the dermis to move a target portion of tissue into a treatment region of the handpiece so that the dermis and the target portion of tissue is elevated relative to surrounding tissue; inserting a tool through an aperture of a wall of the handpiece, through the dermis and into the treatment region so that a distal end of the tool penetrates the target portion of tissue; coupling the tool to a guidance track; coupling the guidance track to the handpiece; and moving the tool along the guidance track in forward, backward and side-to-side motions so that the tool pivots about the aperture and the distal end of the tool is moved within a region of predetermined shape within the target portion of tissue; wherein the tool creates a first dissection in the predetermined shape at a first depth below the surface of the dermis.
