Abstract
A uni-directional, plunger-type electrophysiology catheter handle is designed to reduce the input force a user must apply to deflect the distal end of the catheter. A force amplifier is operatively coupled to a deflection actuator of the handle. The force amplifier can be a pulley or a system of gears. The force amplifier can increase the output force of deflection actuator by the same factor as that by which the user input force is reduced. A variable-friction autolocking system can also be used to reduce the input force a user must apply during initial deflection as compared to later deflection of the catheter.
