Embodiment approach

[0063] Figure 6 An exemplary embodiment of a prosthetic heart valve is illustrated in a collapsed configuration. A covering (eg, fabric or tissue) has been removed from the frame to allow viewing of the frame 600 below. The frame has been rolled out and flattened. Prosthetic valve frame 600 has an atrial region 606 , an annular region 608 and a ventricular region 610 . Frame 600 is formed from a plurality of interconnected struts that form a series of peaks and valleys that can expand and contract relative to each other to allow loading of the frame onto a delivery catheter in a collapsed configuration. , and subsequently expand radially at the target treatment site for implantation. The preferred embodiment is self-expanding and can be made using superelastic nitinol or other self-expanding materials. Shape memory alloys that snap open above the transition temperature may also be used, and expandable members may also be used to expand the frame when plastic deformation (...

Abstract

A sequentially deployed prosthetic cardiac valve includes a self-expanding frame having an atrial skirt, a ventricular skirt, and an annular region disposed therebetween. A first anterior tab is disposed on an anterior portion of the frame. A posterior tab is on a posterior portion of the self-expanding frame. The frame may be designed so that any portion may expand sequentially in any desired order. For example, a portion of the first anterior tab and a portion of the posterior tab may partially self-expand first. Next, the first anterior tab may fully self-expand before the posterior tab fully self-expands. The posterior tab may fully self-expand next followed by the ventricular skirt, or the ventricular skirt may self-expand next followed by full expansion of the posterior tab.
