Abstract:
1. A system for treating tissue with light, comprising: a laser device with a pulsed light output and a controller for the laser device, wherein the controller implements a user interface which permits a user to specify input parameters for defining microablation treatment parameters and wherein the controller controls the laser light output to achieve the desired microablation treatment parameters specified by the user; the laser device being selectable through the controller to control the laser device output to produce an ablative pulsed laser output and a non-ablative heating output, the non-ablative heating output heating targeted subsurface tissue to create a thermal affected zone and cause non-ablative collagen remodeling; wherein the controller is further configured to control the laser light output such that the laser light output comprises a plurality of consecutive pulses, at least one of the plurality of consecutive pulses being an ablative pulsed laser output followed by non-ablative heating, the at least one ablative pulsed output and the non-ablative heating output being overlapping in area of effect on the tissue; and, wherein the at least one ablative laser pulse causes at least one microchannel to be formed in the tissue, the at least one microchannel providing a conduit to apply non-ablative heating to the targeted subsurface tissue; wherein the light with which the tissue is treated has a wavelength of at least about 9 um; wherein the at least one microchannel has a width from about 50 to less than about 200 um; and wherein a plurality of microchannels are formed in the tissue based on a density of microchannels determined by one or more of the microablation treatment parameters or an operator of the system.
