Abstract
An example probe multi-spot, multi-fiber, laser probe includes a plurality of optical fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, and a cannula having a distal end and surrounding the plurality of optical fibers along at least a portion of the laser probe at or near the distal end of the laser probe. A distal pass-through element is positioned within the cannula and at or near the distal end of the cannula and has a groove and/or channel corresponding to each fiber and through which a respective optical fiber passes, and is formed so as to induce a radial rotation of each of the plurality of optical fibers, relative to a central longitudinal axis of the cannula, as the respective optical fiber passes through the distal pass-through element.
