The present invention is a catheter actuation handle 14 for deflecting a distal end 18 of a tubular catheter body 12 , the handle including an auto-locking mechanism, 54 . The handle comprises upper and lower grip portions 24 a , 24 b, an actuator 20 , and an auto-locking mechanism, 54 . The auto-locking mechanism 54 is adapted to hold a deflected distal end 18 of the catheter 10 in place without input from the operator. When the distal end 18 of the catheter 10 is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator 20 . The auto-locking mechanism 54 acts by providing a second force that resists this force from the distal end 18 and holds the distal end 18 in place. As a result, the operator does not need to maintain contact with the buttons 22 a , 22 b to maintain the distal end 18 in a set position once placed there by actuating the actuator 20.
