An endoprosthesis that has a plurality of annular elements, each connected to an adjacent annular element at least one connection location. Each annular element includes an interconnected series of struts, selected strut members of which are each connected to adjacent strut members at a longitudinal apex. The selected strut members extend to a strut end portion at a location on the longitudinally opposite site of the annular element from the apex. At least one of the strut members includes a first end portion at a first end of the strut member, which is located at the strut end portion, an intermediate portion hingedly connected to the first end portion, and a second end portion hingedly connected to the intermediate portion and extending to the apex. The endoprosthesis has a delivery diameter when in a delivery condition and a deployed diameter when in a deployed condition. Some of the strut members can have a nesting feature that is configured for nestingly receiving another strut member when the endoprosthesis is in the delivery condition. A scaffolding body of the endoprosthesis can have an inner and outer component, each having a set of interconnected strut members. The interconnected strut members of one component overlap those of the other to define a cooperating cell pattern. Also, the body of the endoprosthesis can be configured to naturally tend to contract when the body is smaller than a predetermined diameter and naturally tend to expand when the body is larger than a predetermined diameter.
An endoprosthesis, comprising:
An endoprosthesis, comprising a plurality of strut members interconnected to form a repeating pattern of interconnected cells, each cell including at least two arrowhead portions extending longitudinally and directed in opposite directions, each arrowhead portion connected with an arrowhead portion of an adjacent cell, wherein the cells are connected in a generally tubular shape having a delivery condition for facilitating delivery of the endoprosthesis to a deployment site and a deployed condition for deployment in a vessel at the deployment site.
An endoprosthesis, comprising:
An endoprosthesis, comprising:
An endoprosthesis comprising a generally tubular scaffolding body, the scaffolding body having a delivery configuration at a first diameter and a deployed configuration at a second diameter, the second diameter being greater than the first diameter, the scaffolding body having an outer component including a first set of interconnected strut members, the scaffolding body further having an inner component including a second set of interconnected strut members;
