    摘要： Systems and methods for delivery a medical device to a heart valve annulus are disclosed. A method of delivering a medical device to a heart valve annulus includes: (1) aligning a first imaging sensor such that a view of the first imaging sensor is along a primary plane of the heart valve annulus; (2) aligning a second imaging sensor such that a view of the second imaging sensor is along a longitudinal axis of the heart valve annulus; (3) attaching a delivery system holding the medical device to a delivery arm; (4) adjusting the delivery arm to set an angle of the delivery system perpendicular to the primary plane using images from the first imaging sensor; (5) adjusting the delivery arm to center the delivery device in the heart valve annulus using images from the second imaging sensor; and (6) deploying the medical device into the heart valve annulus.

    摘要： A delivery device includes a central elongate structure including an annular member at the distal end, a sheath, a plurality of tethers extending through the central elongate structure, a handle, and a control on the handle. The handle is connected to the elongate structure, the sheath, and the plurality of tether. The control is configured to move the sheath proximally and distally over the central elongate structure. The annular member includes a plurality of pockets extending radially therearound. Each tether includes a feature on a distal end thereof configured to fit within a pocket of the plurality of pockets to hold the tether in place.

    摘要： A prosthetic mitral valve includes an anchor assembly, a strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween.

    摘要： A delivery device includes a central elongate structure, a sheath, a plurality of tethers extending through the central elongate structure configured to hold a cardiac valve, a cutting mechanism, a handle, and a control. The sheath is configured to slide over the central elongate structure. The cutting mechanism is configured to cut the tethers upon activation to release the cardiac valve. The handle is connected to the central elongate structure. The control on the handle is configured to activate the cutting mechanism.

    摘要： A replacement mitral valve includes an anchor assembly including a ventricular anchor, an annular central portion, and an atrial anchor, an annular strut frame disposed radially within the anchor assembly, a central annular member between the anchor assembly and annular strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly is configured to compress native cardiac tissue between the ventricular anchor and the atrial anchor. The central annular member is connected to both the anchor assembly and the annular strut frame so as to connect the anchor assembly to the annular strut frame.
