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.
Claims20
A system comprising:
- a plurality of tissue anchors;
- a template catheter comprising a first configuration in which the template catheter has a low profile and a second configuration in which the template catheter is expanded to be positioned relative to a valve annulus, the template catheter comprising a plurality of pathways;
- an anchor catheter configured to move along a pathway of the plurality of pathways of the template catheter to deliver a tissue anchor of the plurality of tissue anchors to the valve annulus;
- and
- a transvalvular band configured to move along a suture toward the tissue anchor, wherein the transvalvular band comprises an eyelet configured to receive the suture.
