A combined hemostasis valve and drive mechanism is provided. The hemostasis valve has a valve body with a first and second leg. The first leg has a proximal port, a distal port and a lumen extending between the proximal port and the distal port. At least one valve is located in the lumen adjacent the proximal port to permit an interventional device to be passed therethrough. The second leg extends at an angle relative to the first leg and is in fluid communication with the first leg. A rotating male luer lock connector is rotatably connected to the first leg proximate to the distal port. It is configured to secure a guide catheter and has a driven member. The drive mechanism has a drive member removably interfacing with the driven member and a motor operatively connected to the drive member. The motor rotates the guide catheter about its longitudinal axis in a first direction and opposing second direction in response to rotation of the motor in a first direction about an axis of the motor and an opposing second direction about the axis of the motor, through rotation of the drive member, driven member and rotating male luer lock connector.
