1. A method for replacing a native aortic valve comprising:
- endovascularly delivering completely out of a delivery catheter a replacement valve and an anchor comprising an expandable braid to an anchor site within the native aortic valve; and
thenactively foreshortening the anchor to radially expand the anchor to an expanded shape to secure the anchor at the anchor site, wherein the foreshortening step comprises applying a distally directed force on a deployment system interface at a proximal end of the anchor.
