摘要:
A stent is provided for an endoprosthesis having a main body portion and two leg portions, particularly suitable for treatment of an abdominal aortic aneurism. The stent includes barbs that are twisted and shaped set to point radially outward. Each barb, as formed, points substantially perpendicular relative to the longitudinal axis of the stent, even when in a non-deployed configuration. The motion to move the barb into a deployed configuration for gripping tissue is a twisting motion which moves the barb from being substantially aligned with the circumference of the stent to extending radially outwards from the stent.
