Prosthetic heart valve with reduced stitching
First Claim
1. An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the prosthetic valve comprising:
- an annular frame including a plurality of angled strut members;
a skirt member disposed inside the frame and secured to the frame, the skirt member including a plurality of extension portions extending radially outwardly through the frame and wrapped around at least one strut member adjacent the extension portions, the extension portions defining respective openings, extension portions on opposite sides of the at least one strut member being wrapped around the at least one strut member in opposite directions such that the at least one strut member is outside the bounds of the openings defined by the extension portions; and
a cord member threaded through the openings of at least a portion of the plurality of extension portions in a longitudinal direction through the openings to secure the skirt member to the at least one strut member.

17. An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration, the prosthetic valve comprising:
-
an annular frame including a plurality of angled strut members; a skirt member secured to an edge portion of a valve leaflet to form a leaflet-skirt assembly, the leaflet-skirt assembly being disposed inside the frame and secured to the frame, the skirt member including first and second longitudinal edge portions and a plurality of extension portions extending from at least one of the longitudinal edge portions radially outwardly through the frame, the extension portions defining tubular portions, sequential extension portions along a longitudinal axis of the skirt member on opposite sides of at least one strut member being wrapped around the at least one strut member in opposite directions such that their respective tubular portions are coaxially aligned with each other on the outside of the frame; and a cord member threaded through at least a portion of the plurality of extension portions to secure the skirt member to the at least one strut member.

19. A method, comprising:
-
situating a skirt member adjacent a strut member of a frame of a prosthetic valve, the skirt member including a plurality of extension portions defining respective openings, the skirt member being situated such that the plurality of extension portions extend radially outwardly through the frame, the prosthetic valve being radially collapsible to a collapsed configuration and radially expandable to an expanded configuration; wrapping at least a portion of the plurality of extension portions around the strut member such that extension portions on opposite sides of the strut member are wrapped around the strut member in opposite directions with the at least one strut member being outside the bounds of the openings defined by the wrapped extension portions; and threading a cord member through the openings of the extension portions wrapped around the strut member in a longitudinal direction to secure the skirt member to the frame. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
