Abstract
Improved stent configurations exhibiting limited recoil, resistance to compression and improved longitudinal flexibility are disclosed. The stent comprised of a plurality of annular elements aligned to form a cylindrical stent body. The annular elements are comprised of a plurality of open, generally boomerang-shaped segments interconnected top-to-bottom around each of the annular elements. Adjacent annular elements are interconnected by interconnecting element.
Claims16
A generally cylindrical, radially expandable stent comprised of
- a plurality of annular elements aligned to form a cylindrical stent body,
- each element comprised of a plurality of open, boomerang-shaped segments, each segment having a top and a bottom, the segments interconnected top-to-bottom around each of the annular elements,
- adjacent annular elements interconnected in one or more places.
A generally cylindrical, radially expandable stent comprised of
- a plurality of annular elements aligned to form a cylindrical stent body,
- each element comprised of a plurality of open, boomerang-shaped segments interconnected top-to-bottom around each of the annular elements, and
- interconnecting U-shaped elements interconnecting adjacent ends of each boomerang-shaped segment to a neighboring segment in an adjacent annular element.
A generally cylindrical, radially expandable stent comprised of
- a plurality of annular elements aligned to form a cylindrical stent body,
- each element comprised of a plurality of open, boomerang-shaped segments, each segment having a top and a bottom, adjacent segments in an annular element connected by a link extending from the top of a segment to the bottom of an adjacent segment,
- adjacent annular elements interconnected by one or more interconnecting elements, each interconnecting element extending from an end of a boomerang-shaped segment in one annular element to an end of a boomerang-shaped segment in an adjacent annular element.
