Percutaneous Mitral Annular Stitch to Decrease Mitral Regurgitation
First Claim
Patent Images
1. A catheter system, comprising:
- a catheter defining a lumen therethrough;
a band deployment unit that is structured to deploy a mitral annulus band through said lumen of said catheter; and
a mitral annulus band adapted to be deployed through said lumen of said catheter by said band deployment unit,wherein said mitral annulus band is structured to attach to a posterior portion of a mitral annulus or posterior portion of mitral valve tissue of a mitral valve of a heart of a patient and said mitral annulus band is structured to also attach to an anterior portion of said mitral annulus or anterior portion of mitral valve tissue of said mitral valve, andwherein said mitral annulus band is structured to decrease a distance between said posterior and anterior portions of said mitral annulus while in operation to alleviate mitral regurgitation in said heart of said patient.

Abstract
This invention relates to methods and devices for treatment of regurgitation by connecting the anterior and posterior mitral annulus with a plurality of stitches or anchors called “mitral annulus bands”, instead of anchoring via the coronary sinus.

9. A mitral annulus band, comprising:
-
a first clip structured to attach to a posterior portion of a mitral annulus of a patient'"'"'s heart; second clip structured to attach to an anterior portion of said mitral annulus of said patient'"'"'s heart; and a cross member between said first clip and said second clip, wherein a length of said cross member is adjustable when said first clip is attached to said posterior portion of said mitral annulus and when said second clip is attached to said anterior portion of sad mitral annulus to thereby decrease a distance between said posterior and anterior portions of said mitral annulus to decrease an amount of mitral regurgitation.
