Transvalvular intraannular band for mitral valve repair
First Claim
Patent Images
1. A transvalvular intraannular band, the transvalvular band comprising:
- an elongate body having a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion connected to the first end and the second end, wherein the central portion comprises a convex arcuate shape and comprises a plurality of crossing struts encapsulated by a material such that the plurality of crossing struts are fixed relative to each other, the crossing struts intersecting at an intersection zone, the central portion configured to be displaced transversely from an intraannular plane when the band is attached to an annulus;
wherein the first end and the second end are configured to be attached to the annulus within the intraannular plane and the central portion is configured to be convex in a direction of outflow to support valve leaflets at a point displaced toward a ventricle from the intraannular plane, wherein the first end and the second end reside on a septal-lateral axis transverse to coaptive edges of the valve leaflets when the band is attached to the annulus, and wherein the band does not comprise an annuloplasty ring.

Abstract
Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.
