1. A catheter deployment system comprising:
a first catheter having a catheter body with a distal end and a proximal hub;
gripping features on the catheter body distal of the proximal hub;
a free-standing support structure having at least one support post having a gap for receiving the catheter body; and
a clamp structure on the support structure, the clamp structure comprising a single screw which is configured to be advanced and retracted to cause the clamp structure assume an opened position, a closed position, and a plurality of intermediate positions between the opened and closed positions;
wherein (a) the gripping features of the catheter body may be inserted into and removed from the gap on the clamp structure when the clamp structure is in its opened configuration, (b) the gripping features of the catheter body may be rotated and axially translated within the clamp structure when the clamp structure is in a first intermediate position, (c) the gripping features of the catheter body may be rotated but not axially translated within the clamp structure when the clamp structure is in a second intermediate position, and (d) the gripping features of the body of the first catheter are prevented from both rotation and axial translation within the clamp structure when the clamp structure is its closed position.
