Implantable Prosthetic Vascular Valve
First Claim
Patent Images
1. A prosthetic valve for implantation in a vessel, wherein the valve allows primarily one-way flow of a fluid within the vessel and wherein the valve comprises a generally cylindrical tube comprising:
- an outer surface defining an outer diameter,an inner surface defining an inner diameter,an inlet,an outlet,a central portion between the inlet and the outlet, andat least two leaflets, wherein, when the valve is in a relaxed state, the leaflets are at least partially in contact with one another and substantially prevent a fluid from flowing from the outlet to the inlet, and wherein, upon application of pressure from the direction of the inlet, the leaflets separate from contact to allow a fluid to flow from the inlet to the outlet.

45. A prosthetic valve for implantation in a vessel, wherein the valve allows primarily one-way flow of a fluid within the vessel and wherein the valve comprises a generally cylindrical tube comprising:
-
an outer surface defining an outer diameter, an inner surface defining an inner diameter, a flared inlet, a flared outlet, a central portion between the inlet and the outlet, and at least two leaflets, wherein, when the valve is in a relaxed state, the leaflets are at least partially in contact with one another and substantially prevent a fluid from flowing from the outlet to the inlet, and wherein, upon application of pressure from the direction of the inlet, the leaflets separate from contact to allow a fluid to flow from the inlet to the outlet.
