Venous valve with sinus
First Claim
Patent Images
1. A venous valve, comprising:
- a structural member having an inlet region that defines an inlet cross sectional area, a middle region that defines a middle cross sectional area, and an outlet region that defines an outlet cross sectional area, the inlet cross sectional area being different than the middle cross sectional area, and the inlet cross sectional area being at least approximately equal to the outlet cross sectional area;
a first valve leaflet connected to the structural member, the first valve leaflet including a first inflow surface and a first outflow surface opposite the first inflow surface, and being configured to shift between an open position and a closed position; and
a sinus defined by a volume between the structural member at the middle cross sectional area and the first outflow surface of the first valve leaflet in the open position.

19. A method, comprising:
-
forming a middle region in a venous valve frame with an inlet region and a outlet region, the middle region being substantially different than the inlet region, and the inlet region being at least approximately equal to the outlet region; and
coupling valve leaflets to the venous valve frame, where a free edge of the valve leaflets are located adjacent the middle region to form a sinus between the middle region in the venous valve frame and the valve leaflets. - View Dependent Claims (20, 21, 22, 23, 24, 25)
