1. An endovascular delivery system, comprising:
- an elongate outer tubular device having an open lumen and opposed proximal and distal ends with a medial portion therein between;
a prosthesis holder disposed within said outer tubular device, said prosthesis holder comprising;
an axial guidewire extending through said prosthesis holdera body surrounding said axial guidewire, said body comprising at least two generally cylindrical markers aligned in a direction parallel to said axial guidewire and each spaced an equal distance from said axial guidewire; and
an outer surface, upon which a prosthesis may be secured prior to delivery.

Abstract
An endovascular delivery system for an endovascular prosthesis includes a radiopaque marker system for accurate delivery of the prosthesis. The radiopaque marker system is disposed within a prosthesis or stent holder within the delivery system. The radiopaque marker system includes a plurality of radiopaque markers that provide different views rotation of the prosthesis or stent holder.

28. A method of delivering a prosthesis within a body lumen, comprising the steps of:
-
(a) providing a delivery system comprising; (i) an elongate outer tubular device having an open lumen and opposed proximal and distal ends with a medial portion therein between; and (ii) a prosthesis holder disposed within said outer tubular device, said prosthesis holder comprising; an axial guidewire extending through said prosthesis holder a body surrounding said axial guidewire, said body comprising at least two generally cylindrical markers aligned in a direction parallel to said axial guidewire and each spaced an equal distance from said axial guidewire; an outer surface; and a prosthesis secured to said outer surface; (b) inserting said delivery system within a body lumen and directing said prosthesis holder to a desired location within the lumen; (c) using a device to view the location of the generally cylindrical markers; (d) aligning said prosthesis holder at a rotational angle based upon the generally cylindrical markers; and (e) releasing said prosthesis within said body lumen.
