A projector includes an integrator illumination optical system. The first attenuator receives an optical signal emitted by a transmitter of a first transceiver and delivers the received optical signal to a receiver of a second transceiver. Light is refracted from the time light is incident on the first curved surface to the time the light is emitted from the second curved surface. The construct can be configured to be disposed in tissue to draw the tissue toward bone, and the coaxial region can be deconstructed so that the first and second limbs can be used to help secure the desired location of the tissue with respect to the bone.
