Abstract
A stent is provided having attachment members for allowing attachment of a sheath or sheaths. Accordingly, a practitioner is able to selectively choose a desirable sheath, such as a polymeric sleeve, a biomaterial, or a natural blood vessel, at a point-of-use and attach it to the sheath. The attachment members may be bendable tabs and/or secondary support stents.

A stent comprising a radially-expandable body having first and second axial ends, at least one bendable tab extending from said first axial end, said tab being bendable to at least partially overlap said body for forcibly engaging a sheath.
A method of preparing a covered stent for implantation, said method comprising:
- providing a stent having a radially-expandable body with first and second axial ends, at least one bendable tab extending from said first axial end;

- and
- bending at least one of said tabs into engagement with said sheath.
A covered stent comprising a main stent having a radially-expandable body, at least one support stent, and a sheath interposed between said body and said at least one support stent with no portions of said main stent being in contact with said at least one support stent.
A method of preparing a covered stent for implantation, said method comprising:
- providing a main stent having a radially-expandable body;
- disposing a sheath in concentric arrangement with said body;
- and,
- disposing at least one support stent externally of said sheath such that said sheath is interposed between said body and said at least one support stent, and no portion of said main stent is in contact with said at least one support stent.
