Stent design with sheath attachment members
First Claim
1. A stent comprising a radially-expandable body having first and second axial ends, and at least one bendable tab extending from said first axial end, each bendable tab comprising two free ends, each bendable tab having a first configuration and a second configuration, when the bendable tab is in the first configuration the two free ends of the bendable tab are directed in a first direction and when the bendable tab is in the second configuration the two free ends are directed in a second direction opposite the first direction, the bendable tab at least partially overlapping the body in the second configuration;
- wherein said at least one tab is connected to said body via a single bendable stem, the stem being straight when the bendable tab is in the first configuration, the stem having a bend when the bendable tab is in the second configuration.

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.

17. A stent comprising a radially-expandable body having first and second axial ends, and at least one bendable tab extending from said first axial end, each bendable tab comprising two free ends, each bendable tab having a first configuration and a second configuration, when the bendable tab is in the first configuration the two free ends of the bendable tab are directed in a first direction and when the bendable tab is in the second configuration the two free ends are directed in a second direction opposite the first direction, the bendable tab at least partially overlapping the body in the second configuration
wherein said tab generates a relative pressing force with said body to hold a sheath in place, said sheath being not bonded to said tab with said pressing force solely acting to hold said sheath in place.

18. A prosthesis comprising:
-
a plurality of circumferential bands, one of the plurality of circumferential bands forming a first end of the prosthesis, another of the plurality of circumferential bands forming a second end of the prosthesis, the plurality of circumferential bands including first circumferential bands of a first wavelength, each first circumferential band comprising; a plurality of first struts interconnected by a plurality of first turns directed towards a first end of the prosthesis and a plurality of second turns directed towards a second end of the prosthesis, each turn engaged to two of the plurality of first struts forming a first unit of the first circumferential band, the first unit having a first configuration; a plurality of tabs, each tab comprising a turn and two second struts, a first end of each second strut engaged to the turn and a second end of each second strut being a free end, the turn and two second struts of the tab having a second configuration, the second configuration being the same as the first configuration of the first unit of the first circumferential band, each tab engaged to an end of the prosthesis; a first sheath, the first sheath engaged to the prosthesis by at least some of the plurality of tabs. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
