Abstract

Unique semi-circular papillary muscle and annulus bands are described that are useful for modifying the alignment of papillary muscles, a mitral valve annulus and/or a tricuspid valve annulus. Methods to effect the alignment are also described and an unique sizing device that can be used for such alignment is described.

Claims

1. A method for reconstruction of cardiac geometry comprising:

attaching an annuloplasty device to an annulus of a heart valve of a ventricle;

inserting a papilloplasty device through trabeculae of papillary muscles of the ventricle; and

connecting the annuloplasty device to the papilloplasty device to prevent the devices from moving away from each other after the respective attaching and inserting, wherein the annuloplasty device is connected to the papilloplasty device by at least two neo basal stay chords such that the chords pass through the valve trigones before being directly connected to the annuloplasty device.

2. The method of claim 1, wherein a ratio of about 0.8 is fixed between an aortic valve annulus diameter and an intertrigonal distance.

3. The method of claim 1, wherein the method fixes a substantially similar distance between papillary muscle tips, papillary muscles to mitral fibrous trigones and intertrigonal distance.
