Abstract
An apparatus for treating tissue includes a first energy application device to direct energy at tissue of a patient to cause at least one channel to be formed and a controller to control application of energy from the first energy application device to form the at least one channel. The at least one channel may be in the shape of a spiral-like shape or may be in a flower-like shape. Mechanisms are provided to help open channels formed in the human skin structure. A second energy application source may be used to maintain the channel open after formation. The controller may cause the first energy application device to form a plurality of channels of varying depth, width and distribution over the human skin surface. The apparatus to control the application of energy may be operated using a foot-activated pedal.
