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 transluminal access or via thoracotomy.

A method of delivering and anchoring a transvalvular band to a valve annulus of a valve, the method comprising:
- positioning a delivery catheter to deliver a first tissue anchor of a plurality of tissue anchors to the valve annulus;
- delivering the first tissue anchor to the valve annulus, wherein the first tissue anchor comprises a first suture;
- delivering the transvalvular band to the valve annulus, wherein the transvalvular band moves along the first suture toward the first tissue anchor, wherein the transvalvular band comprises a first aperture to receive the first suture;
- and
- moving a first locking clip along the first suture, wherein the first locking clip secures the transvalvular band to the valve annulus.
A method of delivering and anchoring a transvalvular band to a valve annulus of a valve, the method comprising:
- delivering a first tissue anchor of a plurality of tissue anchors to a first location on the valve annulus, the first tissue anchor having a first suture extending from the first tissue anchor;
- delivering a second tissue anchor of the plurality of tissue anchors to a second location on the valve annulus, the second location different from the first location, the second tissue anchor having a second suture extending from the second tissue anchor;
- moving a first end of the transvalvular band toward the first tissue anchor;
- disposing a first locking clip over the first end of the transvalvular band and securing the first end of the transvalvular band to the valve annulus;
- moving a second end of the transvalvular band toward the second tissue anchor;
- and
- disposing a second locking clip over the second end of the transvalvular band and securing the second end of the transvalvular band to the valve annulus.
A method of delivering and anchoring a transvalvular band to a valve annulus of a valve, the method comprising:
- delivering a first tissue anchor of a plurality of tissue anchors to a first location on the valve annulus, the first tissue anchor having a first suture extending from the first tissue anchor;
- delivering a second tissue anchor of the plurality of tissue anchors to a second location on the valve annulus, the second location different from the first location, the second tissue anchor having a second suture extending from the second tissue anchor;
- positioning a delivery catheter relative to the valve and moving a first end of the transvalvular band through the delivery catheter toward the first tissue anchor, wherein the first suture passes through a first aperture of the first end of the transvalvular band;
- and
- moving a second end of the transvalvular band through the delivery catheter toward the second tissue anchor, wherein the second suture passes through a second aperture of the second end of the transvalvular band.
