Abstract
Methods and apparatus for delivering prosthetic segments to a body lumen, utilize a delivery device having an elongated flexible member including proximal and distal ends, a plurality of prosthetic segments arranged near the distal end and axially along the elongated flexible member and an outer sheath slidably disposed over at least a portion of the prosthetic segments. The delivery device also includes a control mechanism coupled with the outer sheath and the elongated flexible member, wherein the control mechanism is adapted to retract the sheath a fixed distance, the fixed distance selectable by an operator to expose a selected number of prosthetic segments and create a spacing between a proximal prosthetic segment in the selected number and a distal prosthetic segment remaining with the elongated flexible member.
