    摘要： A prosthetic valve delivery device includes a handle and a delivery catheter. The delivery catheter includes a central elongate member extending from the handle and a proximal sheath configured to slide over and relative to the central elongate member. The proximal sheath is connected to a hollow helical strand, and the hollow helical strand is configured to rotate to retract the proximal sheath and expose at least a portion of the prosthetic valve.

    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 there between. 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 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 delivery system for delivering a medical device includes a delivery device. The delivery device may include an outer delivery sheath having a compartment at a distal end thereof, the compartment configured to receive the medical device. The delivery device may also include a nosecone catheter positioned radially within the outer delivery sheath, the nosecone catheter having an inner tube configured to receive a guidewire therethrough, and an outer tube, an inflation lumen defined between the inner tube and the outer tube. The delivery device may further include a nosecone that has a length that may be adjusted by pushing an inflation medium into the balloon nosecone or withdrawing the inflation medium from the balloon nosecone via the inflation lumen, the balloon nosecone being reversibly coupled to the nosecone catheter.
