Abstract
Systems and methods to place a prosthesis to have a preselected overlap with a receiving structure are provided. In one embodiment, a delivery system may include a primary sheath comprising a primary sheath lumen. The delivery system may further include a secondary sheath comprising a secondary sheath lumen. The primary sheath may be at least partially received within the secondary sheath lumen such that the primary sheath may translate longitudinally within the secondary sheath lumen. The delivery system may further include a prosthesis having proximal and distal ends and being received within the primary sheath lumen adjacent to the primary sheath distal end in a contracted delivery state. The delivery system may further include a length reference mechanism that indicates a length of the primary sheath distal end that extends distal to the secondary sheath distal end during the contracted delivery state of the prosthesis.
