1. A medical device comprising:
- a tube comprising a lumen and a longitudinal axis;
a longitudinal displacer configured to be moved relative to the tube, the longitudinal displacer being configured to transmit a longitudinal force to the tube when the longitudinal displacer is moved relative to the tube;
a cut along a distal end of the tube, wherein the cut comprises a helical or a spiral cut; and
a handle, wherein a proximal end of the tube is secured to the handle;
wherein a distal end of the tube is curved or angled relative to the longitudinal axis of the tube; and
wherein the tube is configured to rotate about the longitudinal axis of the tube when a longitudinal force is transmitted to the tube by the longitudinal displacer when the longitudinal displacer is moved relative to the tube.

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.
