Patent ID: 7935145

Claim:
An annuloplasty ring for implantation in a mitral valve annulus designed to correct ischemic mitral valve insufficiency, the native mitral valve being located at the orifice between the left atrium and left ventricle and having two leaflets which coapt to form a one-way valve within an overall orifice area, the annuloplasty ring comprising: a generally oval shaped ring body having a metallic core and oriented about a central flow axis, the flow axis defining an upward direction and a downward direction, the downward direction corresponding to the direction of blood flow through the mitral valve annulus from the left atrium to the left ventricle, and wherein in plan view as seen along the flow axis the ring body has a major axis perpendicular to a minor axis, the major and minor axes being perpendicular to the flow axis, the ring body having, in atrial plan view, an anterior section generally defined between an anterolateral trigone and a posteromedial trigone, and a posterior section around the remaining periphery of the ring body and between trigones, the posterior section being divided into three sequential segments, (P 1 ), (P 2 ), and (P 3 ), starting from the anterolateral trigone and continuing in a counterclockwise direction, wherein the minor axis intersects both the anterior section and the (P 2 ) segment of the posterior section, and wherein a portion of the posterior section deflects downward with respect to the remaining sections of the ring body to a single apex; and, wherein, given a predetermined major axis dimension, the ratio of the minor axis dimension to the major axis dimension is less than 3:4.
