摘要：
A steerable cavity creation device comprising: a shaft, a tubing extending therethrough, a hypotube within the tubing, and a pull wire within the hypotube； a deflectable zone on the distal end of the device, wherein the hypotube has a distal zone having slots, wherein the deflectable zone is movable from a substantially straight configuration to a deflected configuration； a controller on the proximal end of the device, actuated by rotation about a longitudinal axis, wherein upon rotation of the controller a proximally directed force is exerted on a movable actuator attached to the pull wire to change the curvature of the deflectable zone, wherein the hypotube is held stationary when the movable actuator applies force to the pull wire； an input port positioned distally on the device relative to the controller； and a cavity creating element carried by the deflectable zone.
