1. A method of performing a neurovascular procedure, comprising the steps of:
providing an access catheter coupled to a catheter hub;
magnetically coupling the access catheter and the catheter hub to a hub adapter across a sterile barrier so that axial movement of the hub adapter causes the hub adapter to exert a magnetic force across the sterile barrier on the catheter hub that causes axial movement of the catheter hub and the access catheter along the sterile barrier, the hub adapter being axially movably carried by a support table;
driving the access catheter axially in response to movement of the hub adapter axially along the support table until the access catheter is positioned to achieve supra-aortic vessel access;
decoupling the access catheter from the hub adapter after supra-aortic vessel access is achieved;
magnetically coupling a procedure catheter to the hub adapter across the sterile barrier so that the procedure catheter moves axially in response to axial movement of the hub adapter; and
driving the procedure catheter axially in response to axial movement of the hub adapter along the support table.
