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 (22"), the first end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a first longitudinal side of the first annular element and the second end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a second longitudinal side of the first annular element; 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 (22"), the first end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a first longitudinal side of the second annular element and the second end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a second longitudinal side of the second annular element; each ofthe first and second annular elements being expandable between a delivery configuration and a deployed configuration; characterized in that: at least one apex ofthe first annular element includes a foot extension extending between a pair of circumferentially-adjacent strut members, the foot extension including a first foot portion extending circumferentially from the first end of one of the circumferentially-adjacent strut members of the pair and a second foot portion extending circumferentially from the first end of the other of the circumferentially-adjacent strut members of the pair, the first and second foot portions joined at a toe portion of the foot extension, and at least one apex of the second annular element is defined by a direct interconnection between circumferentially-adjacent strut members, and the first and second annular elements being aligned longitudinally adjacent to each other along a longitudinal axis and connected to each other at at least one connection location, the at least one connection location is defined by a direct connection between the foot extension and the apex defined by the direct interconnection between circumferentially-adjacent strut members. 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 (22"), the first end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a first longitudinal side of the first annular element and the second end of selected circumferentially-adjacent strut members are interconnected to define apices proximate a second longitudinal side of the first annular element;
