First Claim
Patent Images
1. A system for repairing a tricuspid valve in a patient'"'"'s heart comprising:
- a post having a distal end and a proximal end;
a capture element attached to the distal end of the post, the capture element including;
a plurality of arms each having a first end and a second end, each arm attached at the first end to the post and extending both radially outwardly from the post and proximally, each arm defining an opening at the second end;
a wire passing sequentially through the opening on each arm, whereby tensioning the wire draws the second end of each arm towards the post; and
wherein the post defines a central bore having an orifice at the distal end of the post, and the wire passes into the bore through the orifice.

10. A method of repairing a tricuspid valve having a first leaflet, a second leaflet, and a third leaflet in a heart of a patient, the method comprising:
-
passing an elongate post between the first leaflet, the second leaflet, and the third leaflet; opening a wire into a circular shape that surrounds the post, thereby providing a space between the wire and the post; manipulating the post and the wire until a tip of the first leaflet, a tip of the second leaflet, and a tip of the third leaflet are positioned within the space between the wire and the post; applying a tension force to the wire, thereby reducing a circumference of the circular shape and thereby capturing simultaneously the tip of the first leaflet, the tip of the second leaflet, and the tip of the third leaflet between the post and the wire; and further including locking the wire into a fixed final circumference. - View Dependent Claims (11, 12, 13, 14, 15, 16)
