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.
Claims19
A medical device comprising:
- a catheter and a radially expandable stent mounted on the catheter, the stent comprising a hollow, cylindrical body comprising first and second rings extending circumferentially around the cylindrical body, the first and second rings each comprising a plurality of closed members, each closed member comprising a longer strut and a shorter strut connecting curved peak and valley segments, the longer and shorter struts each comprising a curved portion curved substantially symmetrically about a single circumference of the stent such that the closed members within a ring form a nested chevron pattern;
- circumferential connectors between the longer strut and the shorter strut of circumferentially adjacent closed members;
- and
- at least one longitudinal connection between the first and second rings.
1 more element
A stent comprising:
- a plurality of interconnected rings, each ring extending around a circumference of the stent, each ring comprising a plurality of closed members, each closed member defining a V-shaped opening, each V-shaped opening being symmetric across a midline that comprises a stent circumference, each closed member comprising a longer bent strut and a shorter bent strut, wherein the closed members within a ring form a nested chevron pattern.
