Embodiment Construction

[0042] The present disclosure relates to embodiments of catheter-based prosthetic heart valves. Several exemplary embodiments of prosthetic heart valves are disclosed herein, and in the accompanying picture displayed in . These embodiments should not be construed as limiting in any way. On the contrary, the present disclosure relates to all novel and non-obvious features and aspects of the various disclosed embodiments, both alone and in various combinations and subcombinations with each other.

[0043] figure 1 is a perspective view of a prosthetic heart valve 10 according to one embodiment picture . picture The illustrated prosthetic valve is adapted to be implanted in the native aortic annulus, although in other embodiments it may be adapted to be implanted in other native annulus of the heart. The prosthetic valve 10 may have three main components: a stent or frame 12 , a valve structure 14 and an inner skirt portion 16 . The prosthetic valve 10 is configured to be ...

Abstract

A prosthetic heart valve according to the present disclosure includes a radially collapsible and expandable annular frame and a leaflet structure including a plurality of leaflets mounted within the frame. In particular embodiments, the frame can have a commissural attachment portion configured to support the valve at a location spaced radially inward toward the longitudinal flow axis of the prosthetic valve relative to the frame portion constraining the movable portion of the leaflets. The commissure of the leaflets. As the leaflets open under the pressure of blood flowing through the prosthetic valve, the movable portion of the leaflets is held at a position spaced inwardly from the inner surface of the frame so as not to rub against the leaflets.

Description

technical field [0001] The present disclosure relates to embodiments of prosthetic heart valves, and delivery systems for implanting a prosthetic heart valve. Background technique [0002] The human heart can suffer from a variety of valvular diseases. These valvular diseases can lead to significant cardiac dysfunction and eventually require replacement of the natural valve with an artificial valve. There are many known artificial valves and many known methods of implanting these artificial valves in humans. [0003] A variety of surgical techniques are available to replace or repair diseased or damaged natural valves. Due to stenosis and other heart valve diseases, thousands of patients undergo surgery each year in which a defective natural heart valve is replaced by an artificial valve. Another less drastic method for treating a defective valve is by repair or reconstruction, which is typically used on minimally calcified valves. The problem with surgical therapy is th...
