A system for the advancement or retraction of a guide catheter has a base member, support, linear actuator and bedside support. The base member has a hemostasis valve affixed which includes a valve body with a first leg having a proximal port, a distal port and a lumen with a linear axis 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 valve body has a second leg extending at an angle relative to the first leg and has a lumen in fluid communication with the lumen of the first leg. The support is affixed to the base member such that it functions to move the base member and its affixed valve in concert with the movement of the linear actuator along its linear axis. The liner actuator to which the support is affixed has a linear axis along which it may be advanced or retracted in a continuous or incremental manner. The bedside support is slidingly affixed to the linear actuator to allow the linear actuator to move relative to the bedside support.
