A method is proposed for generating Bessel-like optical beams with arbitrary trajectories in free space. The method involves phase-modulating an optical wavefront so that conical bundles of rays are formed whose apexes write a continuous focal curve with pre-specified shape. These ray cones have circular bases on the input plane; ...

Short-segment tracheal stenosis is often treated by segmental resection and end-to-end anastomosis. Longer-segment stenosis can sometimes be treated using dilation, laser therapy, bronchoscopic stent insertion and segmental resection and reconstruction. Long-segment restenosis with a buildup of scar tissue due to successful resection surgery in the past represents a particular therapeutic ...
