Abstract
A method of manufacturing a prosthetic heart valve includes coupling a plurality of prosthetic leaflets to each other, and coupling the plurality of prosthetic leaflets to a cuff, to form a valve assembly. The valve assembly may be coupled to a stent to form the prosthetic heart valve. The valve assembly may be formed prior to the plurality of prosthetic leaflets being coupled to the stent and prior to the cuff being coupled to the stent.
Claims7
A method of manufacturing a prosthetic heart valve, the method comprising:
- coupling a plurality of prosthetic leaflets to each other, each of the plurality of leaflets having a free edge and a scalloped edge;
- coupling a portion of the scalloped edge of each of the plurality of prosthetic leaflets at spaced apart locations to a straight first edge of a cuff, to form a valve assembly;
- positioning the plurality of prosthetic leaflets on the luminal side of a stent and wrapping the cuff around an inflow edge of the stent so that at least a portion of the cuff is positioned on the abluminal side of the stent;
- and
- coupling the valve assembly to the stent to form the prosthetic heart valve;
- wherein the valve assembly is formed prior to the plurality of prosthetic leaflets being coupled to the stent and prior to the cuff being coupled to the stent.
