A system for controlling multiple computerized medical devices includes a passive sterile mouse and an active mouse-sensing base for sensing a position of the passive sterile mouse and generating a control signal for controlling at least one computerized medical device. A sterile mouse pad is selectively positioned over the active mouse sensing base for sealing the active mouse-sensing base thereunder. A multiplexer is coupled to the active mouse-sensing base for receiving the control signal and providing the control signal to the at least one computerized medical device enabling control of the at least one computerized medical device, within a sterile field during an interventional procedure.
