Abstract
A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.
Claims10
A stent comprising:
- a plurality of proximal and distal apices connected by a plurality of generally straight portions,
- where each proximal apex comprises a first curved portion and each distal apex comprises a second curved portion, where the first curved portion and the second curved portion each comprises at least one radius of curvature, and the radius of curvature of at least one of the proximal apices is greater than the radius of curvature of at least one of the distal apices;
- and
- where a first radius of curvature of one of the proximal apices is from about 4 mm to about 9 mm.
