1. A biomedical valve device for implantation in a body vessel of an animal in need thereof, comprising:
- a first frame member having a first closed circumference having a first length;
a second frame member connected to the first frame member, the second frame member having a second closed circumference having a second length that is less than the first length; and
a tissue valve attached to the second frame member.

Abstract
Biomedical valve devices, support frames for use in such devices, methods of making such devices, and methods of treating animals, including humans, for valve-related conditions are described. The biomedical valve devices can includes a native tissue valve attached to a support frame or a tissue attached to a support frame in a manner to form a valve. The tissue valve or tissue can be autogenous to the animal being treated.

19. A biomedical valve device, comprising:
-
first and second interconnected frame members, the first frame member having a first axial length, the second frame member having a second axial length that is shorter than the first axial length, the second frame member defining a relatively wide base portion and a relatively narrow upper portion;
a tissue valve defining a valve orifice, the tissue valve attached to the second frame member such that the valve orifice is disposed on the upper portion of the second frame member.

20. A method of treating an animal, comprising the steps of:
-
providing a support frame comprising a first frame member having a first closed circumference having a first length and a second frame member connected to the first frame member, the second frame member having a second closed circumference having a second length that is less than the first length;
harvesting a tissue valve from said animal;
attaching the tissue valve to the support frame to form a biomedical valve device; and
implanting the biomedical valve device in a body vessel of said animal.
