Prosthetic valve that permits retrograde flow
First Claim
Patent Images
1. An implantable medical device that provides a valve for regulating fluid flow through a body vessel, comprising:
- a support frame having radially compressed and radially expanded configurations; and
at least one leaflet having first and second edges and being moveable between a first position that permits said fluid flow in a first direction and a second position that substantially prevents said fluid flow in a second, opposite direction, the first edge attached to the support frame and the second edge being free of the support frame;
wherein a portion of the support frame and the second edge of the at least one leaflet cooperatively define an opening that permits a controlled amount of fluid flow in the second, opposite direction.

13. An implantable medical device that provides a valve for regulating fluid flow through a body vessel-comprising:
-
an expandable support frame; and
at least one leaflet attached to the support frame, the at least one leaflet being formed of a bioremodellable material and moveable between a first position that permits said fluid flow in a first direction and a second position that substantially prevents said fluid flow in a second, opposite direction;
wherein the support frame and the at least one leaflet cooperatively define an opening that permits a controlled amount of fluid flow in the second, opposite direction. - View Dependent Claims (14, 15, 16)

22. An implantable medical device that provides a valve for regulating fluid flow through a body vessel, comprising;
-
an expandable support frame;
a first leaflet formed of a bioremodellable material and having first and second edges, the first edge attached to the support frame, the first leaflet defining a first opening; and
a second leaflet formed of a bioremodellable material and having third and fourth edges, the third edge attached to the support frame and the fourth edge cooperating with the second edge of the first leaflet to define a valve aperture having open and closed configurations, the second leaflet defining a second opening;
wherein the first and second openings permit a controlled amount of fluid flow through said medical device when the valve aperture is in the closed configuration. - View Dependent Claims (23, 24)
