Expandable stent and method of use
First Claim
Patent Images
1. A stent comprising:
- a series of circumferentially disposed cylindrical rings, each such ring including a series of apexes extending toward a proximal side and a series of apexes extending toward a distal side, wherein apexes of adjacent cylindrical rings are nested within one another and wherein adjacent cylindrical rings are linked by bridging members extending between apexes located on the same side of each ring, the bridging elements extending from a cylindrical ring alternatingly extend between the apexes of the distally and proximally adjoining cylindrical rings; and
transverse sections extending between apexes of the cylindrical rings which are sufficiently curved such that transverse sections extending from the same apex substantially contact one another.

Abstract
A configuration for expandable stents wherein a series of circumferentially disposed serpentine elements are spaced such that apexes defined by adjacent serpentine elements are nested within one another and only apexes extending along the same side of each serpentine element are linked. Such configurations impart enhanced coverage areas, expansion ratios and radial strength to the stent.
