Abstract
A mode mixer is described for mixing themodes of optical fibers in a laser catheter adapted to be inserted in arteries for treatment of arterial tissue or obstructions. The mode mixer creates microbends in the fibers by physically deforming the fibers, such as by mechanically pressing the fibers against a rigid member to adjust the spot size of light exiting the fibers.
