1. A robotic catheter system, the system comprising:
a first drive mechanism configured to move a first elongated medical device disposed within a lumen of a second elongated medical device along a longitudinal axis of the first elongated medical device;
a holder to secure a proximal end of the second elongated medical device;
a first wiper assembly disposed between the holder and the first drive mechanism, in a fixed position with respect to the holder, and configured to wipe the first elongated medical device;
a housing to the holder and the first wiper assembly are fixed;
a second wiper assembly configured to wipe the second elongated medical device; and
a second drive mechanism disposed between the holder and the second wiper assembly, the second drive mechanism configured to move the proximal end of the second elongated medical device along its longitudinal axis away from the second wiper assembly, causing the holder and the first wiper assembly to move away from the second wiper assembly,
wherein the first drive mechanism is configured to maintain the first elongated medical device substantially stationary with respect to the second wiper assembly while the second drive mechanism moves the proximal end of the second elongated medical device along its longitudinal axis away from the second wiper assembly, and
wherein movement of the proximal end of the second elongated medical device along its longitudinal axis away from the second wiper assembly causes movement of the housing away from the second wiper assembly.
