Abstract
This invention provides prosthesis delivery systems with tips constructed to permit both easier advance into the body and easier removal from the body after expanding the prosthesis. The tip includes a distal taper that can gently widen a lumen during advance in instances where the lumen is narrower than the tip and a proximal taper that can gently widen the lumen on retraction in instances where the prosthesis does not immediately expand the lumen to provide clearance for the larger diameter tip.
