摘要：
A method for endovascularly replacing a patient's heart valve including the following steps: endovascularly delivering an anchor and a replacement valve supported within the anchor to a vicinity of the heart valve in a collapsed delivery configuration, the anchor having grasping elements adapted to grasp tissue in a vicinity of the heart valve; expanding the anchor, thereby rotating the grasping elements; and grasping the tissue with the rotating grasping elements.
