Patent ID: 8852265

Claim:
A method for making an implantable radiopaque stent having a length, the stent comprising: arranging a plurality of elongated filaments comprising at least one non-radiopaque filament and at least one radiopaque filament for permanent attachment to form a hollow tubular structure having a length, the elongate filaments traverse the length of the hollow tubular structure in a direction transverse to a longitudinal axis of the tubular structure, the at least one radiopaque filament having a diameter that is larger than a diameter of the at least one non-radiopaque filament, the tubular structure providing a tubular wall defining an interior surface and an exterior surface and having opposed open first and second ends; arranging the at least one radiopaque filament in a helix configuration about a centerline of the tubular structure with a common axis; and applying a radiopaque compound to an intersection of adjacent filament ends located at one of the opposed open ends, the radiopaque compound comprising radiopaque material and polymeric material, wherein the radiopaque compound and the radiopaque filament improve external imaging of the tubular structure on imaging equipment.
