Abstract
A control handle includes a housing and at least one control wire that extends from the housing to terminate at a distal tip. A steering assembly is coupled with the at least one control wire for selectively tensioning the at least one control wire to effectuate movement of the distal tip. The steering assembly includes at least one cam that is rotatable about an axis and presents a winding surface that extends circumferentially. The at least one control wire is connected to the at least one cam. An actuator dial is rotatable about the axis and coupled with the at least one cam for rotatably driving the at least one cam from a neutral position to an actuated position to at least partially wind the control wire about the winding surface and to tension the at least one control wire for deflecting the distal tip.
