Abstract
A steerable catheter, such as a dilator, includes an elongated shaft including a proximal end portion and a distal end portion, an end effector disposed at the distal end portion of the shaft, and a handle disposed at the proximal end portion of the shaft. The end effector includes a dilation portion disposed proximate the distal end portion of the shaft, a transition portion disposed distally on the dilation portion, and a distal tip portion disposed distally on the transition portion. The tip portion is movable relative to the dilation portion. The handle includes a tip portion steering actuator enabling a user to steer the tip portion. The tip portion has a tip portion diameter. The dilation portion has a dilation portion diameter which is greater than the tip portion diameter. The transition portion tapers from the tip portion diameter to the dilation portion diameter.
