A probe tip assembly includes an optical fiber for channeling light energy and a straightening tube circumscribing at least a portion of the optical fiber. The straightening tube includes a first metallic material and is moveable between a first position and a second position. The tip assembly also includes a guiding member circumscribing the optical fiber and the straightening tube. The guiding member includes a second metallic material and a curvable portion configurable between a pre-formed curved state defining a radius of curvature and a straightened state. The guiding member also includes a plurality of notches, wherein, as the straightening tube is retracted from the first position to the second position, the guiding member transitions from its straightened state to its pre-formed curved state.
