Method and apparatus for repairing a mitral valve
First Claim
1. A method for beneficially displacing a papillary muscle, the method comprising:
- anchoring one end of an implant suture to a trigone or central fibrous body of the mitral valve;
passing another end of the implant suture through a papillary muscle so that the implant suture extends between a trigone or central fibrous body of the mitral valve and the papillary muscle;
tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve; and
securing the tensioned implant suture to the displaced papillary muscle so as to maintain the displaced papillary muscle in position relative to the trigone or central fibrous body of the mitral valve;
wherein the foregoing steps of anchoring, passing, tensioning and securing are all effected while the heart is beating;
wherein a fixed anchor is used to anchor one end of the implant suture to a trigone or central fibrous body of the mitral valve;
wherein the fixed anchor is secured against the atrial side of the mitral annulus; and
wherein the fixed anchor is secured against the atrial side of the mitral annulus by;
passing a free end of a suture from the left ventricle, through the mitral annulus and into the left atrium;
retrieving the free end of the suture in the left atrium and drawing the free end of the suture through the mitral leaflets, into the left ventricle and out of the heart;
securing one end of an implant suture to the free end of the suture suture retrieved from the left atrium, wherein the implant suture has the fixed anchor secured to its other end; and
using the suture to tow the implant suture into the left ventricle, through the mitral leaflets, through the left atrium, through the mitral annulus and through the left ventricle until the fixed anchor is seated against the atrial side of the mitral annulus.

Abstract
A method for beneficially displacing a papillary muscle, the method comprising: anchoring one end of an implant suture to a trigone or central fibrous body of the mitral valve; passing another end of the implant suture through a papillary muscle so that the implant suture extends between a trigone or central fibrous body of the mitral valve and the papillary muscle; tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve; and securing the tensioned implant suture to the displaced papillary muscle so as to maintain the displaced papillary muscle in position relative to the trigone or central fibrous body of the mitral valve; wherein the foregoing steps of anchoring, passing, tensioning and securing are all effected while the heart is beating.

anchoring one end of an implant suture to a trigone or central fibrous body of the mitral valve; passing another end of the implant suture through a papillary muscle so that the implant suture extends between a trigone or central fibrous body of the mitral valve and the papillary muscle; tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve; and securing the tensioned implant suture to the displaced papillary muscle so as to maintain the displaced papillary muscle in position relative to the trigone or central fibrous body of the mitral valve; wherein the foregoing steps of anchoring, passing, tensioning and securing are all effected while the heart is beating; and wherein the step of tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve is accomplished while observing the beating heart with echocardiogram.

7. A method for beneficially displacing a papillary muscle, the method comprising:
-
anchoring one end of an implant suture to a trigone or central fibrous body of the mitral valve; passing another end of the implant suture through a papillary muscle so that the implant suture extends between a trigone or central fibrous body of the mitral valve and the papillary muscle; tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve; and securing the tensioned implant suture to the displaced papillary muscle so as to maintain the displaced papillary muscle in position relative to the trigone or central fibrous body of the mitral valve; wherein the foregoing steps of anchoring, passing, tensioning and securing are all effected while the heart is beating; wherein the step of tensioning the implant suture while displacing the papillary muscle toward the trigone or central fibrous body of the mitral valve is accomplished by; advancing a sliding anchor over the implant suture; advancing a cannulated tool against the sliding anchor so that the sliding anchor engages the papillary muscle and displaces the papillary muscle toward the trigone or central fibrous body of the mitral valve; and tensioning the implant suture while the cannulated tool is engaged with the sliding anchor. - View Dependent Claims (8, 9)
