A method of implanting a prosthesis in a patient at a treatment site includes the steps of providing a prosthesis delivery sheath with an alignment device, loading a prosthesis into the sheath, advancing the sheath in a patient up to the treatment site, and viewing at least one of a rotational and an axial position of the alignment device at the treatment site and, if the sheath is not in a desired position, moving the sheath to the desired position based upon the position of the alignment device. The alignment device can be a pair of markers on opposing sides of a longitudinal axis of the sheath such that, when viewed from a side of the sheath, the pair forms a given shape that communicates to a user a direction in which the sheath needs to rotate minimally to align the markers and form the given shape. |
