ACTUATION HANDLE FOR A CATHETER

摘要

The present invention is a catheter actuation handle (14) for deflecting a distal end (18) of a tubular catheter body (12). The handle (14) comprises a grip portion (22a,b), a first actuator (20), stationary gear racks (72a,b), moveable gear racks (76a,b), pinion gears (66a,b), and a second actuator (22a,b). The grip portion (22a,b) is coupled to the proximal end of the body (12). The first actuator is pivotally coupled to the grip portion (22a,b). The stationary gear racks (72a,b) are fixed relative to the grip portion (22a,b). The moveable gear racks (76a,b) are moveable relative to the grip portion (22a,b) and couple to the actuation wires (81a,b). The pinion gear (66a) is coupled to the first actuator and located between, and engaged with, the stationary gear rack (72a) and the moveable gear rack (76a).
