Abstract: A bridge vessels-proximal anastomosis supporting device for coronary artery bypass grafting and a manufacturing method thereof. The bridge vessels-proximal anastomosis supporting device for the coronary artery bypass grafting comprises an arc-shaped body, an elliptical bottom edge is arranged at the lower part of the arc-shaped body, a circular port is arranged at the right side of the arc-shaped body, a notch is formed between the rightmost end of the bottom edge and the lowermost end of the port, the diameter R of the circular port is 4 mm, 5 mm, 6 mm, 7 mm or 8 mm, the major axis a of the elliptical bottom edge is 13 mm, and the minor axis of the elliptical bottom edge is the same as R. The arc-shaped body is formed by weaving titanium-nickel alloy wires. The bottom edge and the port are provided with a supporting edge made of a heavy metal material, and the supporting edge is fixed with the wires through medical non-absorbable sutures in a wrapping manner.
