Abstract
A system for treating a diseased native valve in a patient includes a valve prosthesis and a delivery device. The prosthesis includes an anchor and a frame. The delivery device includes an outer sheath, an inner shaft, an anchor guide, and a tether. The anchor is shaped to encircle chordae or leaflets of a native valve. The frame is configured to sit within the anchor. The inner shaft is positioned within the outer sheath and translatable and rotatable relative to the outer sheath. The anchor guide is attached to a distal end of the inner shaft and has a curved distal section. The tether is configured to detachably couple to the anchor and to longitudinally translate the anchor within the inner shaft and anchor guide. The anchor is configured to be actuated from a delivery configuration to the deployed configuration when the anchor is translated out of the anchor guide.
