1. An implantable endoluminal prosthesis adapted for placement within a body, comprising:
- a stent member having an outer surface when said stent member is in an expanded configuration;
a graft member;
a first tape member having a first width and a second tape member having a second width different from said first width;
said first tape member covering only a portion of said outer surface of said stent member;
said second tape member covering only a portion of said outer surface of said stent member;
at least one of said first tape member and said second tape member being bonded to said graft member and securing the stent member and graft member together.

Abstract
The invention consists of an endoluminal prosthesis adapted for placement at a bifurcation site within the body. The stent or stent-graft may be constructed to have segments of differing structural properties. A section of the stent-graft may be constructed to have a single-lumen tubular stent member covering a multilumen graft member. The stent-graft may comprise at least two modular components adapted for in situ assembly. An extended cylindrical interference fit may be used to seal the modular components.

10. An endoluminal prosthesis, comprising:
-
a stent member having an outer surface when said stent member is in an expanded configuration; a graft member having a generally tubular shape when said endoluminal prosthesis is in said expanded configuration; said stent member and said graft member generally coaxial to one another when said stent is in said extended configuration; a first tape member having a first width and a second tape member having a second width different from said first width; said first tape member helically configured about an axial length of said graft member when said graft member is in said expanded configuration, and said first tape member covering a portion of said outer surface of said stent member and securing said stent member and said graft member together; said second tape member covering a portion of said outer surface of said stent member. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An implantable endoluminal prosthesis adapted for placement within a body, comprising:
-
a stent member having a first stent member segment with a outer surface and a second stent member segment having a outer surface; a graft member having a first graft member portion and a second graft member portion; said first tape member having a first width and covering only a portion of said outer surface of said first stent member segment, said first tape member being bonded to said first graft member portion and securing the first stent member segment and said first graft member portion together; said second tape member having a second width and covering only a portion of said outer surface of said second stent member segment, said second tape member being bonded to said second graft member portion and securing the second stent member segment and said second graft member portion together; said second width different from said first width.

21. An implantable endoluminal prosthesis adapted for placement within a body, comprising:
-
a stent member having an expandable and expanded configuration, said stent member having an outer surface when in said expanded configuration; a graft member; said stent member comprising a first stent segment and a second stent segment; a first tape member having a first width and covering a portion of an outer surface of said first stent segment and securing the first stent segment and the graft member together; a second tape member having a second width and covering a portion of an outer surface of said second stent segment; said outer surface of said stent member comprising a portion free of cover by said first tape member; said second width different from said first width.
