Abstract
A catheter extension can include an extension body with a sheath defining a lumen, a cable extending within the lumen, a proximal connector attached to the sheath and configured to couple to a catheter drive mechanism, and a distal connector attached to the sheath and configured to couple to a catheter. An axial biasing member can be coupled to the cable and integrated into either the proximal or distal connector and configured to exert a force on the cable in a first axial direction and permit movement of the cable in a second axial direction. An axial key can be coupled to the cable and integrated into the connector opposite the axial biasing member. The axial key can include a tab attached to the cable and a slot with an inner profile that complements a tab outer profile that can permit the tab to move in within the slot.
