    摘要: Valvular implants and blood vessel closure devices herein are configured to be positioned in the heart and to block regurgitant blood flow from the heart into blood vessels supplying blood to the heart. The valvular implants can have a cover, a membrane, a valve, a resilient frame, and/or other features. Some valvular implants can have anchors to be positioned in the blood vessels, such as in pulmonary veins, and can anchor the implant to the heart wall. Various embodiments of covers and/or membranes act as valves contracting and expanding, to alternately permit and block blood flow. The valvular implants can cover one or more blood vessels, such as one, two, three, or four pulmonary veins, and can also be configured and implanted to block an appendage to the heart, such as the left atrial appendage.

    摘要: A prosthetic heart valve is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The heart valve includes an annular inner frame formed with a plurality of angled first strut members, the inner frame being configured to foreshorten from a first length corresponding to the collapsed configuration to a second length corresponding to the expanded configuration. A leaflet structure is situated at least partially within the inner frame. An outer frame is disposed radially outward of the inner frame and coupled to the inner frame. The outer frame is configured to collapse with the inner frame and radially expand with the inner frame, and includes a plurality of second strut members. Portions of the second strut members are configured to bend radially outwardly into a curved shape as the inner frame and the outer frame move from the collapsed configuration to the expanded configuration.

    摘要: A delivery catheter is in various embodiments configured to deliver an anchoring device to a native valve annulus of a patient's heart, where the anchoring device can better secure a prosthesis at the native annulus. The delivery catheter can includes a distal section that includes one or more spines or is laser cut to assume a particular shape for better facilitating delivery of the anchoring device at the implant site and can include a flexible tube, a first pull wire, and a second pull wire. The flexible tube can comprise a bore extending between the first end and the second end sized for passing the anchoring device therethrough. The distal portion can comprise a first flexing section and a second flexing section. Actuation of the first pull wire and the second pull wire can cause the flexible tube to move from a first configuration to a second configuration.
