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.
Claims18
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;
- an inner tubular member configured to be disposed within an outer tubular device, said inner tubular member comprising a longitudinal axis and a proximal portion comprising:
- a rotatable prosthesis holder comprising a body and a plurality of markers;
- and
- an outer surface, upon which a prosthesis may be secured prior to delivery,
- wherein the plurality of markers comprises a first marker having a longitudinal axis aligned in a direction generally parallel to said inner tubular member longitudinal axis and a second marker having a longitudinal axis aligned in a direction generally perpendicular to said inner tubular member longitudinal axis.
