Claim:
1. A vascular device for cutting and removing occlusive material from body lumens, the device comprising: a catheter body having a proximal end, a distal end, and a center axis along which axial advancement occurs, wherein the distal end is sized and configured for rotation about the center axis from the proximal end of the catheter body; a cutter assembly attached at the distal end of the catheter body, the cutter assembly comprising a cutter configured to rotate about the central axis to cut the occlusive material from the body lumen; a deflecting mechanism configured to deflect the cutter assembly relative to the center axis of the catheter body without necessitating axial advancement of the catheter body in the body lumen; and a torque control device, separate from the deflecting mechanism, the torque control device configured to rotate the distal end of the catheter body while the cutter assembly is deflected, to sweep the cutter assembly in an arc about the center axis to cut occlusive material in a region larger than an outside diameter of the cutter assembly.
