Stents with attached looped ends
First Claim
1. An implantable prosthesis, including:
- a plurality of elongate strands cooperating to form an open-frame tubular structure radially expandable and contractible between an enlarged-radius state and a reduced-radius state, wherein different ones of the elongate strands are integrally coupled to one another along respective end regions thereof to form a plurality of strand couplings along a selected end of the tubular structure; and
a closure member connected to a pair of associated strand couplings and extending between the associated strand couplings to form a loop segment directed axially outwardly from the associated strand couplings.

Abstract
An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.
