Abstract
An endoprosthesis that has an interconnected series of struts, selected strut members connected to adjacent strut members at a longitudinal apex. Strut members include a first 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. Some of the strut members can have a nesting feature 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 which overlap those of the other to define a cooperating cell pattern. Also, the endoprosthesis can be configured to naturally tend to contract when the body is smaller than a predetermined diameter and expand when the body is larger than a predetermined diameter.
