An apparatus, system, and method for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The apparatus and method, which are appropriate for cardiovascular and peripheral vessels, use a pulling member and a spring element, for example a compression spring, to oscillate a distal component disposed at a distal end of the spring element. The apparatus further includes a sleeve covering the spring element and at least a portion of the distal component. The sleeve may reduce friction between the spring element and the vessel lumen as the spring element vibrates during operation of the apparatus. The sleeve may also serve to protect or seal the spring element from blood and/or plaque debris that is loosened from an occlusion during a re-canalization procedure.
