The present invention provides an apparatus for endovascularly replacing a patient's heart valve. In some embodiments, the apparatus includes an expandable anchor supporting a replacement valve, the anchor and replacement valve being adapted for percutaneous delivery and deployment to replace the patient's heart valve, the anchor having a braid having atraumatic grasping elements adapted to grasp tissue in a vicinity of the patient's heart valve.
What is claimed is: 1. An apparatus for endovascularly replacing a patient's heart valve having native leaflets, the apparatus comprising:an expandable anchor supporting a valve, the anchor and valve being adapted for percutaneous delivery and deployment, the anchor having a proximal end, a distal e
What is claimed is: 1. An apparatus for endovascularly replacing a patient's heart valve having native leaflets, the apparatus comprising:an expandable anchor supporting a valve, the anchor and valve being adapted for percutaneous delivery and deployment, the anchor having a proximal end, a distal end, a longitudinal axis, and an outer surface, the anchor braided from a shape memory material, the anchor being expandable from a collapsed delivery configuration to a fully deployed configuration; andleaflet engagement elements are attached to the anchor, the leaflet engagement elements extending distally from the anchor at a location proximal of the distal end of the anchor in both the collapased delivery configuration and the fully deployed configuration, the leaflet engagement elements extending over at least a portion of the outer surface of the anchor,wherein, when the anchor is in the collapsed delivery configuration, the leaflet engagement elements are parallel to the longitudinal axis of the anchor; and when the anchor is in the fully deployed configuration, the leaflet engagement elements are adapted to sandwich the native leaflets between the leaflet engagement elements and the anchor.
