Heart failure mitral annuloplasty ring with multiple sets of suture placement indicia
First Claim
1. An annuloplasty device for an annulus of a mitral valve, comprising:
- a structural component sized for the annulus of the mitral valve, said structural component having a generally C-shaped posterior portion including a central portion and first and second lateral portions; and
a relatively softer outer layer overlying said structural component, said outer layer including means for identifying sets of suturing locations through said outer layer, each said set corresponding to a discrete predetermined amount of cinching of the annulus.

Abstract
An annuloplasty ring includes an anterior portion, and a posterior portion which defines a central portion and two lateral portions. The ring is adapted for optional removal of the anterior and/or the central posterior portion. Removal of the central posterior portion reduces the gradient across the ring providing enhanced valve performance. Removal of the anterior portion preserves normal annular movement. The lateral posterior portions are stiffer than the construction at the anterior and central posterior portions. If the ring is used with the central posterior portion intact, the gradient is also reduced. The ring includes indicia of multiple sets of suture markings, each set identifying a plurality of suture locations about the perimeter of the ring which are adapted to cinch the annulus a predetermined amount about the ring. A single ring may be used to cinch the annulus in accord with relatively different degrees of desired valve area reduction.

13. An annuloplasty device for repair of a mitral valve after heart failure, comprising:
an annuloplasty ring having a posterior portion P with a central portion P2, and lateral portions P1 and P3, wherein said central portion P2 is provided with at most a single set of indicia corresponding to suture locations, and said lateral portions P1 and P3 each include multiple sets of discrete indicia corresponding to different suture locations, wherein said indicia corresponding to each of said sets of indicia on P1 and P3 are spaced apart from each other by a distance different than a distance by which indicia in the other of said sets of indicia on P1 and P3 is spaced apart. - View Dependent Claims (14)
