Abstract

A steerable dilator (100) or catheter including an elongated shaft (102) with a proximal end (104) and a distal end (106), an end effector (200) disposed at the distal end (106) of the shaft (102), and a handle (300) disposed at the proximal end (104) of the shaft (102). The end effector (200) includes a dilation portion (202) disposed proximate the distal end (106) of the shaft (102), and a distal tip portion (206) disposed distally on the dilation portion (202). The handle (300) includes a steering actuator (500). Moving the steering actuator (500) in a first or second actuator direction moves the tip portion (206) in a first or second direction respectively in a first steering plane. Moving the steering actuator (500) in a third or fourth actuator direction moves the tip portion (206) in a third or fourth direction respectively in a second steering plane.
