An intravascular tissue removal tool has an elongated flexible sheath with a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, the lumen having a distal lumen diameter near the distal end cutting elements extending into the lumen near the distal end of the flexible sheath a forceps having an open state and a closed state, and further having an extended position relative to the flexible sheath, in which the forceps is located substantially outside the flexible sheath near the distal end and a retracted position relative to the flexible sheath, in which the forceps is located substantially inside the flexible sheath and an elongated actuation member being attached to the forceps for switching the forceps between the open state and the closed state and for moving the forceps between the extended state and the retracted state.
