Abstract
An intraluminal stent includes a continuous helix of zig-zag wire and loops which connect adjacent apices of the wire. The stent is compressible and self-expandable substantially to a pre-compressed configuration. A method of forming the stent includes bending a length of wire into a zig-zag configuration and a helix and connecting adjacent apices of the wire. A method implanting this stent includes compressing the stent radially, implanting it in a predetermined location of a body vessel, and allowing it to recoil to the configuration it had before compression.
Claims6
An intraluminal stent comprising:
- a predetermined length of elastic wire having a zig-zag configuration and defining a continuous helix with a plurality of hoops;
- a plurality of loop members for connecting adjacent apices of adjacent helix hoops;
- the loop members and the wire being separate members and made of different materials, the stent being compressible and self-expandable substantially to a pre-compressed configuration.
An intraluminal stent comprising:
- a predetermined length of elastic wire having a zig-zag configuration and defining a continuous helix with a plurality of hoops;
- a plurality of loop members for connecting adjacent apices of adjacent helix hoops, each said loop member including a single ligature of suture material tied into a loop;
- the stent being compressible and self-expandable substantially to a pre-compressed configuration.
