Stent having less invasive ends and improved radial force
Abstract:
The present invention provides a stent having less invasive ends and improved radial force. In one embodiment, the stent comprises a series of proximal apices disposed at a proximal end of the stent, a series of distal apices disposed at a distal end of the stent, and at least one angled strut segment disposed between the proximal and distal apices of the stent. At least one apex of the stent may comprise multiple curved portions. In one example, the radius of curvature of one of the curved portions is significantly greater, for example, at least 10 times greater, than each of the other radii of curvature of the apex. The curved portion having the significantly greater radius of curvature may be configured to engage a vessel wall in a less invasive manner.
