| Zusammenfassung: | The invention relates to a steerable catheter. A steerable medical device includes a shaft (14), a steering mechanism (38), and an actuation mechanism (48). The shaft has a proximal portion (16), a distal portion (18), a first traction wire (20), and a second traction wire (22). The distal ends of the first traction wire (20b) and the second traction wire (22b) are coupled to the distal portion of the shaft. The actuation mechanism has a first wheel (40) and a second wheel (42) coupled by a differential mechanism (44). The proximal ends of the first traction wire (20a) and the second traction wire (22a) are coupled to the first wheel and the second wheel, respectively. The actuation mechanism is coupled to the manipulation mechanism. Actuating the actuation mechanism in the first mode of operation causes the distal portion of the shaft to bend in a first plane. Actuating the actuation mechanism in the second mode of operation causes the distal portion of the shaft to bend away from the first plane.
