    摘要: A delivery system for percutaneously deploying a valve prosthesis. The system includes a catheter assembly including a delivery sheath capsule and a handle having an oscillating device. The capsule is configured to compressively retain the valve prosthesis during implantation. After the valve prosthesis is partially exposed during implantation, the oscillating device can create a vibratory motion to reduce the friction between the valve prosthesis and the delivery sheath capsule in order to recapture the valve prosthesis.

    摘要: A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.

    摘要: In some embodiments, a valve prosthesis includes an inlet portion that is substantially s-shaped and configured to engage the floor of the outflow tract of the native heart atrium. In some embodiments, a valve prosthesis includes a chordae guiding element configured to reduce bending of the chordae to reduce stress on the chordae during the cardiac cycle. In some embodiments, a valve prosthesis includes a central portion having an hourglass shape configured to pinch a native annulus in order to provide axial fixation of the valve prosthesis within a valve site. In some embodiments, a valve prosthesis includes a frame having an outflow end that is flared to provide a gap between an outflow end of the frame and an outflow end of prosthetic leaflets when the prosthetic leaflets are fully opened.

    摘要: An embolic protection device includes a first filter configured to be disposed in a first vessel and a second filter configured to be disposed in a second vessel. A first tether extends from a proximal end of the first filter and a first magnet is coupled to the first tether. A second tether extends from a proximal end of the second filter and a second magnet is coupled to the second tether. The device is configured such that when the first filter is disposed in the first vessel and the second filter is disposed in the second vessel, the first magnet and the second magnet are magnetically coupled to each other to couple the first tether to the second tether.

    摘要: Prosthetic heart valve devices and associated methods for percutaneous or transcatheter heart valve replacement are disclosed herein. A heart valve prosthesis configured in accordance herewith includes a frame having a valve support and a plurality of support arms extending therefrom. The plurality of support arms may include a main support arm configured to extend from the valve support for capturing at least a portion of a valve leaflet of a native heart valve therebetween when the valve prosthesis is in an expanded configuration and deployed within the native heart valve. In addition, the plurality of support arms may include multiple supplemental support arms disposed about the circumference of the valve support that when deployed in the expanded configuration are configured to at least partially engage subannular tissue at the native heart valve.
