Claim:
1. An assembly for delivering an implantable prosthesis to a target site in a body, the assembly comprising: an elongate inner delivery member disposed within an outer shaft, the elongated delivery member including a longitudinal axis; and a valve retainer connected to the elongate inner delivery member and disposed within the outer shaft during delivery to a target site in the body, wherein the valve retainer has an outer surface, wherein the valve retainer is configured to releasably secure a proximal end of a prosthesis to the elongate inner delivery member during delivery to the target site in a body, and wherein the valve retainer includes a rotational identifier that identifies the rotational orientation of the valve retainer around the longitudinal axis when the valve retainer is positioned proximate to the target site in the body, wherein the rotational identifier is a notch formed in the outer surface of the valve retainer such that the valve retainer is asymmetric relative to the longitudinal axis.
