Abstract
The present invention provides valve prostheses adapted to be initially crimped in a narrow configuration suitable for catheterization through body ducts to a target location and adapted to be deployed by exerting substantially radial forces from within by means of a deployment device to a deployed state in the target location.

2. A prosthetic valve assembly comprising:
-
(a) a support structure having an inlet end, an outlet end and a plurality of longitudinally rigid support beams disposed thereon, said support structure configured to be radially collapsible and expandable while retaining a fixed longitudinal length; and
(b) a valve comprised of a pliant material having an inlet end and an outlet, said pliant material having a plurality of tabs at said outlet configured to be operably attached to said support beams at said outlet end of said support structure. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for implanting a prosthetic valve assembly comprising:
-
(a) providing a catheter having a proximal end and a distal end;
(b) mounting said prosthetic valve assembly on said distal end, said prosthetic valve assembly comprising (i) a support structure having an inlet end, an outlet end and a plurality of longitudinally rigid support beams disposed thereon, said support structure configured to be radially collapsible and expandable while retaining a fixed longitudinal length; and
(ii) a valve comprised of a pliant material having an inlet end and an outlet, said pliant material having a plurality of tabs at said outlet configured to be operably attached to said support beams at said outlet end of said support structure;
(c) guiding said catheter through said body lumen to a target site with a guiding tool;
(d) deploying said prosthetic valve assembly at said target location; and
(e) retracting said catheter. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
