Abstract
Abstract A prosthetic cardiac valvular member of flexible material includes a flexible stent member which may be either attached to the cardiac valvular member or molded therein. The stent member is formed by a plurality of adjacent filaments which are bound together by suturing, braiding, jacketing or encapsulating. The prosthetic cardiac valvular member may be either a flexible heart valve or an annuloplasty ring. Post members are formed into the stent member when the stent member is used in the flexible heart valve.
