First Claim
1. A robotic catheter system, the system comprising:
- a housing including a first channel having a first axis and a second channel having a second axis, the second channel intersecting the first channel, the second axis is not co-axial and not parallel to the first channel;
a first drive mechanism supported by the housing adjacent the first axis and configured to impart axial movement to a first catheter device along the first axis, the first drive mechanism moveable between an engaged position in which the first drive mechanism engages the first catheter device and a disengaged position in which the first drive mechanism does not engage the first catheter device;
a second drive mechanism supported by the housing adjacent to the second axis configured to impart axial movement to a second catheter device along the second axis, the second drive mechanism imparting axial movement to the second catheter device independent of axial movement of the first catheter device, the second drive mechanism moveable between an engaged position in which the second drive mechanism engages the second catheter device and a disengaged position in which the second drive mechanism does not engage the second catheter device; and
a single manual control configured to allow a user to manually move the first drive mechanism and the second drive mechanism simultaneously between the engaged and disengaged positions;
wherein the first drive mechanism and the second drive mechanism are also configured to be moved between the engaged and disengaged positions by an electronic actuator responsive to a user'"'"'s activation of a control;
wherein the first drive mechanism and the second drive mechanism are configured to be moved between the respective engaged and disengaged positions synchronized with each other.

Abstract
A catheter system including a housing and a first drive mechanism supported by the housing configured to impart movement to a first catheter device is provided. The first drive mechanism is moveable between an engaged position in which the first drive mechanism engages the first catheter device and a disengaged position in which the first drive mechanism does not engage the first catheter device. The catheter system includes a second drive mechanism supported by the housing configured to impart movement to a second catheter device. The second drive mechanism is moveable between an engaged position in which the second drive mechanism engages the second catheter device and a disengaged position in which the second drive mechanism does not engage the second catheter device. The catheter system includes a manual control configured to allow a user to manually move the first drive mechanism and the second drive mechanism between the engaged and disengaged positions. The first drive mechanism and the second drive mechanism are also configured to be moved between the engaged and disengaged positions by an electronic actuator responsive to a user'"'"'s activation of a control. The first drive mechanism and the second drive mechanism are configured to be moved between the respective engaged and disengaged positions synchronized with each other.
