Claims27
A method of manufacturing a replacement venous valve for transcatheter delivery and deployment, comprising:
- cutting a planar and fixated sheet of biological tissue to have a top section and a bottom rectangular section, wherein the top section is cut to resemble the shape of a single cusp having a belly curve;
- folding the top section over the bottom rectangular section to form an apex of a monocusp shape of a leaflet;
- suturing the top section onto the bottom rectangular section to form margins of the monocusp shape;
- and
- rolling opposite lateral edges of the rectangular section into a generally cylindrical shape to form a monocusp leaflet of a replacement venous valve capable of placement via a catheter and operating as a monocusp valve using the monocusp shape.
