Prosthetic valve with leaflet connectors
First Claim
1. Apparatus, comprising:
- a unitary flexible sheet, folded to define;
a panel, defining a plane, and having a first side facing in a first direction away from the plane, and a second side that is opposite the first side;
a first tab, disposed on the first side of the panel, and protruding in the first direction away from the panel; and
a second tab, disposed on the first side of the panel, and protruding in the first direction away from the panel;
a first prosthetic leaflet having a first-leaflet commissural portion disposed between the first tab and the second tab;
a second prosthetic leaflet having a second-leaflet commissural portion disposed between the first tab and the second tab;
wherein;
at the first tab, the sheet is folded to define a first cushion at a downstream edge of the first tab, the first cushion being configured and positioned to inhibit deflection of a downstream portion of the first prosthetic leaflet away from the second prosthetic leaflet and toward the plane, andat the second tab, the sheet is folded to define a second cushion at a downstream edge of the second tab, the second cushion being configured and positioned to inhibit deflection of a downstream portion of the second prosthetic leaflet away from the first prosthetic leaflet and toward the plane.

Abstract
A unitary flexible sheet is folded to define: (i) a panel, defining a plane, and having a first side facing in a first direction away from the plane, (ii) a first tab, disposed on the first side of the panel, and protruding in the first direction away from the panel, and (iii) a second tab, disposed on the first side of the panel, and protruding in the first direction away from the panel. Between the first tab and the second tab are secured (i) a first-leaflet commissural portion of a first prosthetic leaflet, and (ii) a second-leaflet commissural portion of a second prosthetic leaflet. At the first tab, the sheet is folded to define a first cushion at a downstream edge of the first tab. At the second tab, the sheet is folded to define a second cushion at a downstream edge of the second tab.

9. A method, comprising:
-
folding a unitary flexible sheet to define; a panel, defining a plane, and having a first side facing in a first direction away from the plane, and a second side that is opposite the first side, a first tab, disposed on the first side of the panel, and protruding in the first direction away from the panel, and a second tab, disposed on the first side of the panel, and protruding in the first direction away from the panel; securing, between the first tab and the second tab; a first-leaflet commissural portion of a first prosthetic leaflet, and a second-leaflet commissural portion of a second prosthetic leaflet; at the first tab, folding the sheet to define a first cushion at a downstream edge of the first tab, the first cushion being configured and positioned to inhibit deflection of a downstream portion of the first prosthetic leaflet away from the second prosthetic leaflet and toward the plane; and at the second tab, folding the sheet to define a second cushion at a downstream edge of the second tab, the second cushion being configured and positioned to inhibit deflection of a downstream portion of the second prosthetic leaflet away from the first prosthetic leaflet and toward the plane. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
