A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a "T" with the top of the "T" implanted within the lumen of a vascular structure, and the leg of the "T" extending out of the vascular structure through an incision in the vascular structure. The lumen of the implanted portion of the catheter completely occupies the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the "T" of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter. The leg of the "T" is connected to the side wall of the implant portion of the catheter at an angle, such that the axis of the lumen of the leg of the "T" intersects the axis of the lumen of the implanted portion of the catheter at approximately a 45 degree angle.

A tri-leaflet heart valve includes an annular valve base with an inner surface forming an orifice through which blood flows from the upstream side to the downstream side. Three protruding hinges, each with concave sockets on opposite sides, are formed on the inner surface. Each hinge has a downstream face and an upstream face connected by a ridge. Three leaflets are respectively arranged between adjacent hinges. Each leaflet has round pivots on both sides that rest inside the concave sockets, allowing the leaflets to freely rotate in the annular valve base. When the leaflets are subject to a positive pressure from the blood flow, the leaflets are pushed open and allow a central flow. When the leaflets are subject to a negative pressure, the leaflets are closed to occlude the blood flow.
