Problem to be solved: to provide a hemostasis valve for guiding catheter control in a robotic catheter system, with respect to the field of a catheter system for performing diagnosis and \/ or intervention measures.The blood flow stop valve 34 includes a valve body having a lumen extending between the proximal port, the distal port, and the proximal port and the distal port.A valve is disposed in a lumen adjacent to the proximal port.A rotary lube connector 48 is rotatably connected to the valve body near the distal port to attach a guide catheter.The rotary lube connector includes a driven member 56 adapted to be rotatably driven by a drive mechanism.Diagram
