Abstract

A robotic catheter system includes an arch-shaped suspension system comprising a first and second vertical span, a horizontal span between the pair of vertical spans, and at least one robotic catheter head coupled to the horizontal span. The arch-shaped suspension system can include a pair of linear guide blocks that can be attached to a patient bed and in some embodiments the linear guide blocks can be configured to slidably move along a rail. The arch-shaped suspension system can be moved to allow for proper placement of the arch-shaped suspension system for use on a patient or for placing the system away from a patient or for storage. In some embodiments the robotic catheter system can include a suspension system cart for storing and moving the arch-shaped suspension system.
