1. A method of improving valve morphology at target a site, the method comprising:
- providing an apparatus to improve valve morphology, said device having a first bridge portion configured to extend across the center of the valve in a transannular position when the apparatus is positioned and attached to the valve;
attaching a first base portion and a second base portion of the apparatus to tissue at the target site, wherein attachment brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween; and
advancing penetrating members into said tissue, said penetrating members being secured in said tissue and the apparatus, and act as fasteners.

Abstract
Methods and apparatus are provided for valve repair. In one embodiment, the apparatus includes a first bridge portion and a second bridge portion. The apparatus may also include at least one base on each bridge portion. Attachment of the first bridge portion and the second bridge portion brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween.

7. A method of improving valve morphology at target a site, the method comprising:
-
providing an apparatus to improve valve morphology, said device having a plurality of bridge portions each configured to extend across the valve in a transannular fashion when the apparatus is positioned and attached to the valve;
attaching a first base portion of one bridge portion and a second base portion another bridge portion to tissue at the target site, wherein attachment brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween; and
advancing penetrating members into said tissue, said penetrating members being secured in said tissue and the apparatus, and act as fasteners. - View Dependent Claims (8, 9, 10)

12. A device for improving valve morphology at target a site, the method comprising:
-
a bridge portion;
a base of the bridge shaped to allow the intertrigonal distance to expand during systole for proper aortic valve function and allow the native mitral annulus to deform in its physiologic “
saddle”
shape trough out the cardiac cycle;
wherein attachment of the bridge portion brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween.

-
a first bridge portion;
a second bridge portion;
at least one base on each bridge portion; and
wherein attachment of the first bridge portion and the second bridge portion brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A device for improving valve morphology at target a site, the method comprising:
-
a central bridge portion sized and configured to extend across a center of the valve in a transannular position when the apparatus is positioned and attached to the valve annulus;
at least one side bridge portion;
a C-shaped base portion coupling said central bridge to the side bridge portion;
wherein attachment of the central bridge brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween.

27. A method of improving valve morphology at target a site, the method comprising:
-
providing an apparatus having a first configuration, wherein the apparatus has a reduced outer diameter and a second configuration, wherein the apparatus has an expanded outer diameter;
advancing said apparatus in the first configuration along a catheter;
expanding said apparatus into said second configuration;
attaching a first portion and a second portion of the apparatus to tissue at the target site, wherein attachment brings an anterior leaflet of the valve closer to the posterior leaflet and reduces a gap therebetween;
advancing penetrating members into said tissue, said penetrating members being secured in said tissue and the apparatus, and act as fasteners.
