Aortic Valve Annuloplasty Rings
First Claim
Patent Images
1. An aortic annuloplasty ring, comprising:
- a collar having first and second ends that together form a fastener operable to secure the first and second ends together and thereby so shape the collar as to engage the aorta circumferentially; and
a flap depending from the collar for wrapping over the aorta;
the ring being sized to fit around the aorta, and further being transitionable between a first state, in which the fastener does not secure the first and second ends together, and a second state, in which the fastener so secures the first end to the second end that the collar is shaped to engage the aorta circumferentially.

Abstract
An aortic annuloplasty ring may include a ring, having a “C” shape. The ring may be so sized as to fit around and circumferentially engage an aortic root. The ring may be formed at least in part of a biocompatible material so nonresiliently deformable as to permit manual adjustment of the ring. An aortic annuloplasty method may include disposing an aortic annuloplasty ring around an aorta root, the ring having a “C” shape, and the ring being so sized as to fit around and circumferentially engage the aortic root; and deforming the ring to circumferentially engage the aortic root.

15. An adjustable aortic annuloplasty ring, comprising:
-
a collar having first and second ends that together form a fastener operable to secure the first and second ends together and thereby so shape the collar as to engage the aorta circumferentially, the fastener having a plurality of catches on the second end selectively receivable by an aperture in the first end, thereby making the ring adjustable; and
a plurality of flaps depending from the collar for wrapping over the aorta;
the ring being sized to fit around the aorta, and further being transitionable between a first state, in which the fastener does not secure the first and second ends together, and a second state, in which the fastener so secures the first end to the second end that the collar is shaped substantially circularly to engage the aorta circumferentially.

16. An aortic annuloplasty ring, comprising:
-
a ring, having a “
C”
shape, and being so sized as to fit around and circumferentially engage an aortic root;
the ring being formed at least in part of a biocompatible material so deformable as to permit manual adjustment of the ring and so nonresilient as to keep the shape into which it is adjusted. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. An aortic annuloplasty method, comprising:
-
disposing an aortic annuloplasty ring around an aorta, the ring including a collar having first and second ends, the first and second ends forming a fastener operable to secure the first and second ends together, the ring further including a flap depending from the collar;
fastening the first and second ends of the collar to each other, thereby so shaping the collar as to engage the aorta circumferentially; and
wrapping the flap over the aorta. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56)

disposing an aortic annuloplasty ring around an aorta root, the ring having a “
C”
shape, the ring being so sized as to fit around and circumferentially engage the aortic root, and the ring being formed at least in part of a biocompatible material so deformable as to permit manual adjustment of the ring and so nonresilient as to keep the shape into which it is deformed; and
deforming the ring to circumferentially engage the aortic root. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66)
