1. A device for manipulating the shaft of a catheter comprising:

  • a body portion having a lumen sized to receive the shaft of the catheter such that the shaft of the catheter extends lengthwise through the lumen and proximal and distal end portions of the shaft protrude from opposite ends of the body portion;

    a first arm connected to the body portion for rotation about a first pivot axis with respect to the body portion, the first arm comprising a first shaft engaging surface enclosed within the body portion and configured to rotate with the first arm about the first pivot axis; and

    a second arm connected to the body portion for rotation about a second pivot axis with respect to the body portion, the second arm comprising a second shaft engaging surface enclosed within the body portion and configured to rotate with the second arm about the second pivot axis,wherein the first and second arms have a locked position in which the first and second arms are oriented about the first and second pivot axes such that the first and second shaft engaging surfaces are configured to engage the shaft of the catheter to lock the body portion on the shaft, and an unlocked position in which the first and second arms are oriented such that at least one of the first and second shaft engaging surfaces is configured to be disengaged from the shaft of the catheter so that the body portion is free to rotate and axially translate over the shaft of the catheter.
