An endoprostheses for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen can be formed with a structure, referred to as a stress reliever, designed to distribute and reduce the amount of strain which can act on the movable struts of the stent. Stress relievers can be disposed at a strut junction where one end of a strut is attached to the end of an adjacent strut. The positioning and shape of the stress reliever help to distribute the amount of strain that would otherwise be exerted on the movable struts as the struts move relative to each other. As a result, there is less possibility that the struts will fracture at the strut junction when the struts move from a collapsed position to an expanded position.
