Abstract
An endovascular self-expanding stent system that can include a braid with a proximal end, a distal end, and a lumen formed therebetween. The braid can be formed from one or more wires woven to comprise interstices. A first expansion ring can be connected to the proximal end of the braid. A second expansion ring can be connected to the distal end of the braid. Each expansion ring can include a frame that imparts an outwardly expanding radial force to the braid. The frame can include a plurality of elongate members interconnected by one or more intersections.
Claims20
An endovascular system comprising a self-expanding braid for treating an aneurysm, the system comprising:
- a braid comprising a proximal end, a distal end, and a lumen formed therebetween, the braid formed from one or more wires woven to comprise interstices;
- a first expansion ring connected to the proximal end of the braid;
- a second expansion ring connected to the distal end of the braid;
- wherein, each expansion ring comprises a frame that imparts an outwardly expanding radial force to the braid, the frame comprising a plurality of elongate members interconnected by one or more intersections.
A method of using a braid, the method comprising:
- providing a braid having a proximal end, a distal end, and a lumen formed therebetween by one or more braided wires;
- positioning a first expansion ring with the proximal end, the first expansion ring configured to be self-expanding and apply an outward radial force to the proximal end of the braid;
- positioning a second expansion ring at a distal end of the braid, the second expansion ring configured to be self-expanding and apply an outward radial force to the distal end of the braid;
- engaging at least one of the first and second expansion rings to a delivery wire;
- and
- delivering the braid to an aneurysm by distally advancing the delivery wire.
