Claim Text:
1. A stent for use with a prosthetic heart valve for replacement of a native heart valve comprising an expandable non-woven stent body having a collapsed configuration and an expanded configuration, the stent body including an annulus section adjacent a proximal end of the stent, the annulus section including a plurality of closed cells arranged in a multiplicity of annular rows around a circumference of the stent body, the annulus section in the expanded configuration being generally tubular and adapted to engage the leaflets of the native heart valve and the annulus of the native heart valve with a proximal end of the annulus section adjacent the annulus of the native valve and a distal end of the annulus section adjacent distal ends of the native leaflets, the stent body including a plurality of latch members formed integrally with the annulus section, each of the latch members including a pair of connection struts and an engagement portion adapted to engage an exterior surface of a leaflet of the native valve, the connection struts being connected to the stent body at circumferentially-spaced locations in the annulus section and projecting distally from the locations to distal ends located distal to the annulus section, and the engagement portion being connected to the connection struts adjacent the distal ends thereof and projecting proximally from the distal ends of the connection struts to an engagement portion proximal end unconnected to other structure, each of the engagement portions being spaced from a next adjacent engagement portion around the circumference of the stent.
