Dual wavelength laser treatment device

Abstract

Embodiments of the invention include a compact, lightweight, hand-held laser treatment device that combines the emissions of two separate laser energy sources into a common optical pathway for improved therapeutic effect. In some embodiments, the device includes a housing having separate first and second laser sources disposed within the interior thereof. In some embodiments, the laser energy emissions from the two internal laser sources can be individually or concurrently transmitted to a delivery tip of the device via a laser transmission path also defined within the interior of the housing. In some embodiments, the structural and functional features of the first and second laser sources, in concert with the unique architecture of the laser transmission path, can be configured to provide efficacy and efficiency in the operation of the device within the spatial constraints of the lightweight, hand-held housing thereof.

Benefits of technology

[0033]In some embodiments, the first laser emission and the second laser emission are applied to the target tissue site in pulses. In some further embodiments, the first treatment effect comprises a first ablation depth. In some further embodiments, the second treatment effect comprises a second ablation depth different from the first ablation depth, and the synergistic treatment effect comprises a third ablation depth greater than either one of the first ablation depth and the second ablation depth. In some other embodiments of the method, the second ablation depth is characterized by no ablation.

[0034]Some embodiments of the method include applying a fluid to the target tissue site. In some embodiments, the first
