Abstract

Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.
