Patent ID: 8317744

Claim:
A robotic catheter manipulator assembly comprising: a support member having a longitudinal axis; a catheter manipulation base operably coupled to the support member; a sheath manipulation base operably coupled to the support member, each manipulation base configured to be linearly movable relative to the other manipulation base and to the support member along the longitudinal axis of the support member, the catheter manipulation base being releasably connectable to a catheter cartridge and the sheath manipulation base being releasably connectable to a sheath cartridge; wherein one of the catheter manipulation base and the catheter cartridge includes at least one finger engagable in a substantially linear motion with at least one complementary component in the other one of the catheter manipulation base and the catheter cartridge for controlling deflection of a catheter by pulling a steering wire attached to the catheter and one of the finger and the slider block; and at least one drive mechanism for moving the catheter and sheath manipulation bases relative to each other and to the support member.
