Abstract
A delivery apparatus for implanting a prosthetic implant in a native lumen of the body includes a handle portion, and a first shaft extending from and movable relative to the handle portion. The first shaft has a proximal end portion coupled to the handle portion and a distal end portion. The delivery apparatus further includes a second shaft extending from the handle portion and coaxially disposed within the first shaft. The second shaft has a proximal end portion coupled to the handle portion and a distal end portion configured to mount a prosthetic implant in a radially compressed state. The handle portion of the delivery apparatus also includes a steering assembly configured to move the first shaft longitudinally relative to the second shaft while concurrently flexing the second shaft.
