    摘要: A prosthetic mitral valve includes an anchor assembly, an annular 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 annular strut frame is disposed radially within the anchor assembly. An atrial end of the annular strut frame is attached to the anchor assembly such that a ventricular end of the annular strut frame is spaced away from the anchor assembly.

    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 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 loading device configured to radially collapse an expandable medical implant may include an operating handle having an opening therein extending along a longitudinal axis, a native sheath coupled to the operating handle and partially extending into the opening, such that the native sheath is configured to translate relative to the operating handle parallel to the longitudinal axis, a removable sheath removably coupled to the native sheath, an actuation rod extending parallel to the longitudinal axis at least partially through the opening, a lumen of the native sheath, and a lumen of the removable sheath, a distal end of the actuation rod being configured to be removably coupled to the expandable medical implant, and a first control element movable relative to the operating handle and coupled to the native sheath, the first control element being configured to translate the native sheath and the removable sheath relative to the operating handle.
