Claim:
1. A catheter for debulking of an undesired deposit from an inner surface of at least one of a blood vessel wall and a stent located in a blood vessel, said catheter having a tip section comprising a wall at an end of the tip section, the tip section having a central longitudinal axis, said tip section comprising: circumferentially-directed laser optics comprising a plurality of optical fibers disposed within the wall and positioned parallel to said central longitudinal axis and configured to provide transmission of laser radiation, parallel to said central longitudinal axis from a distal end of said tip section to the undesired deposit, when in use; and a circular-action cutter, wherein said cutter is formed from a distal edge of the wall of said tip section or affixed to said distal end of said tip section's wall inwardly or outwardly to the plurality of optical fibers; and wherein said cutter is positioned outside an optical path of said laser radiation; wherein said circumferentially-directed laser optics is configured to transmit laser radiation for ablating an area of the undesired deposit thereby preparing said area for penetration of said cutter; and wherein said cutter is configured to cut through said ablated area and thereby debulk at least a part of the undesired deposit.
