Abstract
Embodiments of a steerable catheter control system and methods are disclosed. The steerable catheter control system comprises a housing which defines an inner housing and a slide assembly which linearly translates within the inner housing. At least two control wires are positioned through the slide assembly wherein one of the at least two controls wires are indirectly coupled to the slide assembly via the direction reversing element. The steerable catheter control system further comprises a slack limiting element, coupled to at least one of the at least two control wires. The slack limiting element allows for frictional engagement of the control wire to limit slack. The control system includes a control knob for linearly translating the slide assembly, enabling the slide assembly to manipulate the control wires which causes a change in deflection of the steerable catheter.
