Aortic ring (1) made of a flexible, suturable and biocompatible material, having a length, in the implanted state, making it possible to maintain a normal aortic ring diameter, said ring comprising, or being able to be combined with, means for holding the ring in a closed position in its site of implantation, in particular in a subvalvular plane.

Aortic ring and ancillary device for implanting it

Devices and methods are provided for surgical repair of dilated aortic root to restore aortic valve competence while preserving native leaflets. In one aspect of the invention an expandable annuloplasty ring is provided for external placement at the base of a dilated aortic root. The expandable ring is capable of elastically expanding between a first diastolic diameter and a larger second systolic diameter to provide a physiologically representative surgical repair of the aortic root. In a further aspect of the invention, is provided a holder assembly for aortic annuloplasty ring and suitable for other cardiac valve prosthesis. The holder assembly consists of a holder body pivotingly coupled to a handle member through a ball-and-socket arrangement.

Expandable annuloplasty ring and associated ring holder

A method comprises implanting an aortic ring externally on the outer surface and around the aortic root to form a closed-perimeter flexible structure only around the subvalvular region externally of the aortic root, generally adjacent the nadir portion of the valve annulus and below the attachment points of the coronary arteries; and constraining the aortic root with the closed-perimeter structure to an anatomically representative geometry that improves coaptation of the leaflet free margins in the diastolic phase of the cardiac cycle.
