    Abstract: A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.

    Abstract: Embodiments of the present disclosure provide methods of loading a prosthetic heart valve within a delivery apparatus such that it can be used for delivery of the prosthetic heart valve to a native valve site via the human vasculature. The methods can include attaching the prosthetic heart valve to a valve-retaining mechanism at a distal end of the catheter and causing a torque shaft of the delivery apparatus to rotate relative to the catheter, wherein the torque shaft extends within the catheter and is coupled to the valve delivery sheath. Rotation of the torque shaft relative to the catheter can cause relative longitudinal movement between the valve sheath and the prosthetic heart valve such that the prosthetic heart valve is covered by the valve sheath.

    Abstract: A delivery assembly includes a prosthetic device, a catheter shaft, a release wire, a first line, and a second line. The prosthetic device has a first arm and a second arm. The release wire extends through the catheter shaft. The first line includes a first loop. The first line extends from the catheter shaft, through the first arm of the prosthetic device, and to the release wire, where the release wire extends through the first loop. The second line includes a second loop. The second line extends from the catheter shaft, through the second arm of the prosthetic device, and to the release wire, where the release wire extends through the second loop.

    Abstract: Using a catheter, a device is delivered to the heart of a subject. The device includes a cord and multiple anchors distributed along the cord. Subsequently, the device is arranged in an arrangement at the tissue such that the cord is positioned and laid out correspondingly to the tissue. While the device remains in the arrangement, (i) a first subset of the anchors which are positioned for successful anchoring is identified, and (ii) subsequent to the identifying, for each of the anchors of the first subset, a respective anchor launcher is actuated to drive the anchor into the tissue. Subsequently, for each of the anchors that remain not driven into the tissue, (i) the anchor is positioned for successful anchoring, and (ii) a respective anchor launcher is actuated to drive the anchor into the tissue. Other embodiments are also disclosed.

    Abstract: Prosthetic heart valves and methods of implantation thereof are disclosed herein. In embodiments, a prosthetic heart valve includes a self-expandable frame configured to support of valve member and comprising a plurality of interconnected strut members forming a mesh structure. An inflow end and outflow end portions of the mesh structure respectively define an inflow terminal end and an outflow terminal end of the frame. A portion of the frame tapers inwardly from the inflow terminal end to form a reduced diameter section. In implementations, the frame increases in diameter from the reduced diameter section to an intermediate section. In implementations, the valve member is secured to the frame at the inflow end portion. In implementations, the frame further comprises a plurality of retaining arms that extend from the outflow terminal end and are configured to engage with a valve retaining mechanism of a delivery apparatus.

    Abstract: Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.
