Abstract

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 computerized medical devices, within a sterile field during an interventional procedure.
