    摘要： 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.

    摘要： A method for treating a diseased native valve in a patient includes 5 advancing a distal end of a delivery device to a first side of a native valve, deploying an anchor from a delivery configuration to a deployed configuration on the first side of the native valve, and rotating the distal end of the delivery device so as to simultaneously extend the anchor in the deployed configuration through the native valve from the first side to a second side of the native valve and 10 rotate the anchor in the deployed configuration around native chordae.

    摘要： Disclosed herein are prosthetic valve devices, systems, and methods of installation of prosthetic valve devices and systems in a target region of a subject. Prosthetic valve devices disclosed herein comprise a frame structure having expanded and unexpanded configurations aiding in minimally-invasive delivery of the devices to the target region. The prosthetic valve devices include frame structures designed to minimize the amount of material used to form the devices without sacrificing structural strength. The prosthetic valve devices also include frame structures of minimal longitudinal length, allowing easier and more precise delivery and deployment of the devices.
