Annuloplasty repair devices, systems and methods
First Claim
1. An annuloplasty prosthesis for implantation adjacent an annulus of a heart valve of a heart, the annulus having at least an anterior and posterior aspect adjacent anterior and posterior leaflets, respectively, the prosthesis comprising:
- a closed ring body made of a single piece of shape memory material and having a central opening defined entirely by an inner perimeter edge of the ring body, the ring body comprising;
an anterior portion and a posterior portion shaped to conform to, and for implantation adjacent, the anterior and posterior aspects of the annulus, respectively; and
at least a first tissue attachment member having a point configured to secure into tissue of the annulus and integrally connected to and extending from the ring body; and
at least one commissural leg integrally connected to and extending from the ring body, the at least one commissural leg having a total length greater than a total length of the first tissue attachment member.

Abstract
An annuloplasty prosthesis and delivery system for implanting the prosthesis adjacent an annulus of a heart valve having leaflets for adjusting the annulus to improve valve function includes a ring prosthesis made of shape memory material and having tissue attachment members which attach to the annulus in the atrium and commissural legs extending from the ring between the leaflets and secure against the underside of the valve in the ventricle. The prosthesis is carried via an orientation loop and attaches to the heart tissue such that when the prosthesis is manipulated and relaxed the annulus is adjusted to reduce or eliminate regurgitation.

31. An annuloplasty prosthesis being a unitary article made of a single piece of shape memory material for implantation adjacent an annulus of a heart valve of a heart, the annulus having at least an anterior and posterior aspect adjacent anterior and posterior leaflets, respectively, the prosthesis comprising:
-
a closed ring body made of a single piece of shape memory material and having a central opening defined entirely by an inner perimeter edge of the ring body, the ring body comprising an anterior portion and a posterior portion shaped to conform to, and for implantation adjacent, the anterior and posterior aspects of the annulus, respectively; and at least one commissural leg integrally connected to and extending from the ring body, the at least one commissural leg configured such that when the prostheses is implanted, the commissural leg locates near the junction of the anterior and posterior aspects of the annulus and within a ventricle of the heart while the ring body is positioned in an atrium of the heart.
