Endoprosthesis having foot extensions
First Claim
1. An endoprosthesis for delivery in a body lumen comprising:
- a first set of interconnected strut members defining a first annular element, each strut member of the first annular element including a first end and a second end; and
a second set of interconnected strut members defining a second annular element, each strut member of the second annular element including a first end and a second end; and
a radiopaque marker incorporated into the endoprosthesis;
the first annular element and the second annular element aligned longitudinally adjacent to each other along a longitudinal axis and connected to each other with a connector at at least one connection location, the connector includes a first component of a first material and a second component of a bio-absorbable material disposed about at least a portion of the first component, wherein each strut member is free of bio-absorbable material between the first and second ends thereof.

Abstract
Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration. The annular elements are longitudinally aligned and connected at connection locations with connectors, wherein at least one of the connectors is constructed of a bio-absorbable material.
