Prosthetic valves and methods of making

A prosthetic valve, comprising:

• a body defining a longitudinal axis;
• the body comprising at least two leaflets, each leaflet being defined by a tubular member aligned with the longitudinal axis,
• the tubular member comprising a first end, a second end, an exterior surface, and a luminal surface;
• the first end of the tubular member being open and the second end of the tubular member being closed such that the luminal surface of the tubular member forms a top surface of a leaflet, wherein each leaflet comprises a commissure region that is seamlessly continuous with an annulus region.

A method of making a prosthetic valve, comprising:

• providing at least two tubular members, each of the tubular members comprising a tubular member first end, a tubular member second end, an exterior surface, and a luminal surface and defining a tubular member longitudinal axis;
• aligning the at least two tubular members along the tubular member longitudinal axis;
• attaching adjacent tubular members along an adjoining exterior surface in a direction along the tubular member longitudinal axis to form a body, the body comprising a body first end, a body second end, an outer surface, and annular region, and defining a body longitudinal axis, wherein portions of the exterior surface of the adjoined tubular members circumferentially form a wall of the body;
• and
• closing each tubular member at the tubular member second end such that the luminal surface of each tubular member defines a top surface of a leaflet, wherein the portions of the exterior surface at the first end of the adjoined tubular members that do not form the wall of the body define commissures, wherein each leaflet comprises a commissure region that is seamlessly continuous with an annulus region.
