ENDOVASCULAR DELIVERY SYSTEM WITH AN IMPROVED RADIOPAQUE MARKER SCHEME

摘要

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.

主权项

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; an inner tubular member disposed within said outer tubular device, said inner tubular member comprising a proximal portion comprising:
a prosthesis holder comprising a body surrounding an axial guidewire, said body comprising a first generally cylindrical marker aligned in a direction parallel to said axial guidewire and a second generally cylindrical marker aligned in a direction perpendicular to said axial guidewire, wherein said first generally cylindrical marker and said second generally cylindrical marker are spaced an equal distance from said axial guidewire; andan outer surface, upon which a prosthesis may be secured prior to delivery;wherein said prosthesis holder is made of a material that is not fluorescent or radiopaque;wherein said axial guidewire is made of a material that is fluorescent or radiopaque; andwherein said at least two generally cylindrical markers are made of a material that is fluorescent or radiopaque.
