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 (1). An elliptical bottom edge (2) is arranged at the lower part of the arc-shaped body (1), a circular port (3) is arranged at the right side of the arc-shaped body (1), a notch is formed between the rightmost end of the bottom edge (2) and the lowermost end of the port, the diameter R of the circular port (3) is 4 mm, 5 mm, 6 mm, 7 mm or 8 mm, the major axis a of the elliptical bottom edge (2) is 13 mm, and the minor axis of the elliptical bottom edge (2) is the same as R. The body (1) is formed by weaving titanium-nickel alloy wires. The bottom edge (2) and the port (3) are provided with a supporting edge (5) made of a heavy metal material, and the supporting edge (5) is fixed with the wires (4) through medical non-absorbable sutures (6) in a wrapping manner. The device can support blood vessels of an anastomosis so as to prevent the blood vessels from generating collapse or deformation due to squeezing during an operation, thereby delaying occlusion of the anastomosis after the operation, and helping complete postoperative coronary angiography easily, accurately and quickly during re-examination.La présente invention concerne un dispositif de soutien danastomose proximale de vaisseaux en pont pour pontage aorto-coronarien et un procédé de fabrication associé.
