Systems are provided for rotationally aligning the distal end of the medical device relative to the distal mount of the auxiliary system. Additionally or alternatively, systems are provided for facilitating securing of the auxiliary system and other medical device relative to each other. For instance, systems are provided for securing the sheath along the length of the medical device, and subsequently releasing the secure coupling.
