Abstract
A seamless prosthetic valve comprising a continuous tubular member having an outer abluminal surface, a triple walled intermediate portion, and at least a first valve leaflet that is configured to selectively restrict fluid flow through the valve, the triple walled intermediate portion being formed by everting a first end of member over the member, whereby a double walled end is formed, and reverting the first end over the double walled end of the member, the first valve leaflet being formed by suturing the triple walled intermediate portion at a first commissure connection point.

A seamless prosthetic valve, comprising:
- a continuous tubular member having an outer abluminal surface, first and second ends, a triple walled intermediate portion, and at least a first valve leaflet, said first valve leaflet being configured to selectively restrict fluid flow through said seamless prosthetic valve,
- said triple walled intermediate portion being formed by everting said first end of said tubular member over said tubular member to form a double walled first end and a doubled wall portion proximal to and extending from said double walled end, and reverting said first end of said tubular member over said double walled end of said tubular member,
- said first valve leaflet being formed by suturing said triple walled intermediate portion at a first commissure connection point.
