1. A prosthetic valve, comprising;
- an expandable stent comprising a plurality of zigzag ring structures, each of which comprises a plurality of “
V”
structures, each “
V”
structure comprising a base between first and second arms, wherein the ring structures are coupled longitudinally to each other so that at least one “
V”
structure base of each ring structure is attached at a junction to a “
V”
structure base of an adjacent ring structure;
a replacement valve positioned at least partially within the expandable stent and comprising a substantially tubular valve body wall;
a plurality of sutures attaching the valve body wall to the stent at the first and second ends of the stent; and
, at least one intermediate suture located at one of the “
V”
structure bases between the first and second ends and attaching the “
V”
structure base to the valve body.

Abstract
A prosthetic valve including a replacement valve having a tubular valve body wall, an expandable stent having a framework with first and second ends, and suturing holding the framework to the valve body at the first and second ends. The suturing at the first end is colored differently from the suturing at the second end.

14. A prosthetic valve, comprising;
-
an expandable stent having first and second ends and having a framework at least partially defined by plural framework sections and plural junctions between framework sections; a replacement valve positioned at least partially within the expandable stent and comprising a substantially tubular valve body wall and a plurality of leaflets, each of which extends from an inside surface of the valve body wall to a commissure, and wherein the valve comprises a sinus area between each adjacent pair of commissures; a plurality of sutures attaching the framework to the valve body wall at the first and second ends of the stent; and at least one intermediate suture located at a junction of the stent that is adjacent to one of the sinus areas of the valve. - View Dependent Claims (15, 16, 17)

18. A prosthetic valve, comprising;
-
an expandable stent comprising a plurality of zigzag ring structures, each of which comprises a plurality of V-shaped members, wherein each V-shaped member comprises a base between first and second arms, and wherein the ring structures are coupled longitudinally to each other so that at least one V-shaped member base of each ring structure is attached at a junction to a V-shaped member base of an adjacent ring structure; a replacement valve positioned at least partially within the expandable stent and comprising a substantially tubular valve body wall; and a plurality of sutures attaching the framework to the valve body wall at the first and second ends of the stent; and a plurality of intermediate sutures arranged in a pattern, wherein each of the intermediate sutures attaches a junction of the stent to the valve body wall to minimize inward bowing of the valve body wall relative to the stent. - View Dependent Claims (19, 20)
