Abstract: In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises an imaging system that receives a return signal from the aperture. The return signal received from the aperture has a second path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or BBL beam.

Abstract: In one aspect, methods of treating a wound are described herein. A method described herein, in some embodiments, comprises treating a wound, such as a chronic wound, by performing a full field laser ablation in a wound bed of the wound and subsequently performing a fractional laser ablation in the wound bed. Additionally, in some cases, the fractional laser ablation step is carried out at substantially the same time as, or immediately following, the full field laser ablation step. In addition, in some instances, a method described herein further comprises performing debridement in the wound bed prior to performing the full field laser ablation in the wound bed.

Abstract: An applicator is configured with an optical window formed from a first and a second lens section. The applicator is configured for modulating the temperature of a working surface while simultaneously exposing the working surface to a radiation source. The first and the second lens sections form boundaries of a medium cavity for channeling a temperature regulating medium which is preferably a cooled liquid medium. The first lens section has an outer lens and an inner lens which are preferably separated by a distance in the range of 0.1 to 1.0 cm and form boundaries of an insulating region. In a preferred method, a temperature regulating medium is circulated through the medium cavity while exposing a target tissue to laser radiation through the optical window. The insulating region helps reduce fogging of the optical window thereby improving visibility through the window and reducing scattering of the laser radiation. Preferably, the insulating region is under vacuum.

Abstract: A selective aperture for a laser delivery system for providing incision, ablation and coagulation. A laser crystal disposed between two reflective surfaces forms a laser beam. An aperture member positioned between the laser crystal and one of the reflective surfaces includes a substantially circular aperture for passing the laser beam. The size of the aperture is selectively adjustable. The aperture member has a plurality of apertures of various different sizes and is rotatable about an axis of rotation. The axis of rotation is parallel to the longitudinal axis of the laser crystal. By appropriately rotating the aperture member, a selected one of the apertures is positioned to pass the laser beam. A stepper motor and flexible shaft are utilized for rotating the aperture member. At least one of the apertures is surrounded by a beveled portion of the rotatable member. Alternatively, two lasers with different size fixed apertures could be utilized and directed to a common surface.
