Abstract
A catheter with a distal end that rotates through the conversion of linear motion to rotational motion, thus the distal end may be rotated without longitudinally advancing or retracting the distal end. The catheter includes a tube with a single helix or a dual chirality helix cut into the tube, a distal end segment, means for linear displacement of the helix, and means for coupling the junction point of the helix to the distal segment.
