PERCUTANEOUS TRANSVALVULAR INTRAANNULAR BAND FOR MITRAL VALVE REPAIR
First Claim
Patent Images
1. A method of delivering a transvalvular intraannular implant, comprising:
- providing a delivery catheter, the delivery catheter comprising an elongate body;
a movable outer sheath; and
a transvalvular intraannular implant having a longitudinal axis from a first end to a second end and comprising a valve leaflet support portion and an anchoring portion, the valve leaflet support portion at least partially longitudinally offset from the anchoring portion;
percutaneously delivering the delivery catheter to the vicinity of a heart valve annulus;
transforming the implant from a first radially reduced configuration to a second radially enlarged configuration; and
positioning the implant in its second radially enlarged configuration within the heart valve annulus such that the implant is oriented in the valve annulus such that the longitudinal axis of the implant is oriented substantially transversely to a coaptive edge of a heart valve positioned within the valve annulus.

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.

17. A transvalvular intraannular delivery system, comprising:
-
a percutaneous delivery catheter comprising an elongate body; a movable outer sheath; and a transvalvular intraannular implant having a longitudinal axis from a first end to a second end and comprising a valve leaflet support portion and an anchoring portion, the valve leaflet support portion at least partially longitudinally offset from the anchoring portion, wherein the transvalvular implant is configured to be transformable from a first radially reduced configuration to a second radially enlarged configuration;
wherein the transvalvular implant is configured to be housed within the percutaneous delivery catheter in its first radially reduced configuration, wherein the transvalvular implant is configured to be positioned in its second radially enlarged configuration within a heart valve annulus such that the implant is oriented in the valve annulus such that the longitudinal axis of the implant is oriented substantially transversely to a coaptive edge of a heart valve positioned within the valve annulus. - View Dependent Claims (18, 19, 20)
