Transvalvular intraannular band for valve repair

摘要

Aortic regurgitation can be treating by implanting in the aortic 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 aortic valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

主权项

1. An intraannular heart valve implant comprising:
a body having first and second shoulder portions and a convex shaped central portion, wherein the first and second shoulder portions taper from a first width to a second width toward the central portion to reduce resistance to blood flow, wherein the central portion comprises a narrowed portion narrower than part of the first and second shoulder portions to reduce resistance to blood flow, wherein a portion of the body is dimensioned for attachment within an intraannular plane of a heart valve annulus, and wherein part of the implant is configured to be positioned within the intraannular plane of the heart valve annulus such that the central portion extends transversely across a coaptive edge formed by two or three valve leaflets, and such that the central portion is convex in the direction of blood flow to support the two or three valve leaflets and elevate the position of the coaptive edge in the direction of blood flow during closure of the two or three valve leaflets.
