Disclosed are apparatus, method, devices and instruments, including an apparatus that includes a flexible waveguide coupled to a supporting structure, and further coupled to a treatment tip. The apparatus also includes a beam controller to control application of a radiation beam emitted from the flexible waveguide to distribute the beam over an area different than an area covered by direct application of the beam to a single location on a target tissue. Further disclosed is an apparatus that includes a waveguide, coupleable to a laser source, and a thermal protection instrument. The thermal protection instrument includes a tissue contacting member to contact a part of an area of a tissue irradiated by laser radiation, and a beam blocking element to absorb at least some of radiation not absorbed by the area of the tissue, the beam blocking element being thermally isolated from the area of the tissue. |
