摘要： A crimping device for reducing the size of prosthetic heart valve devices and other medical devices. A hydraulically operated piston advances a pusher toward an opening of a funnel. An interior surface of the funnel is configured to provide substantially uniform compression forces to a prosthetic heart valve device between the pusher and the funnel as the pusher advances the prosthetic heart valve device into the funnel. A system may comprise the crimping device and a prosthetic heart valve device positioned between the pusher and the funnel. A technique for using the crimping device includes delivering a pressurized fluid and crimping a prosthetic heart valve device using the interior surface of the funnel.

摘要： Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae (CT). A chordae management catheter (520) is positioned within a ventricle of the heart, the chordae management catheter having a displacement component (530) at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system (2040) is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis (101) at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.

摘要： A prosthetic valve including an inner frame, an outer frame, and a connection assembly interconnecting the frames. The inner frame defines an interior volume for receiving a valve structure within the interior volume. The outer frame surrounds the inner frame. The inner and outer frames are each configured to be transitionable between compressed and expanded conditions. The prosthetic heart valve provides a initial deployed state in which the inner and outer frames are in the expanded condition, and a radial shape of the outer frame is adjustable via the connection assembly to a final deployed state. A shape of the outer frame can be adjusted upon implant to enable radial anchoring at the native annulus, while addressing possible non-uniformities of the native annulus and possible anatomical concerns such as LVOT obstruction.

摘要： Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart. A valve delivery system is introduced into a ventricle of the heart via a ventricular wall of the heart. The valve delivery system has a displacement component (1830) at the distal portion thereof. The valve prosthesis (101) is in a delivery configuration and the displacement component is in a delivery state in which the displacement component has a first outer diameter. While the valve prosthesis is in the delivery configuration, the displacement component of the valve delivery system is radially expanded into an expanded state in which the displacement component has a second outer diameter greater than the first outer diameter. The valve delivery system is advanced towards the annulus of the native valve of the heart with the displacement component in the expanded state to displace chordae tendineae.
