The present invention relates to the technical field of anastomosis devices, and particularly to a minimally invasive proximal anastomosis device for bypass grafting. In view of the problems that the anastomosis site is far from the surgical incision, the operation is difficult, the error tolerance rate is low, resulting in a high risk of coronary ischemia, and for patients with ascending aorta lesions, the risks of aortic rupture, dissection and stroke will also increase, the following technical solutions are proposed: It includes a handle, one end of the handle is fixedly connected with a fixed cylinder, and sliding grooves are formed on both sides of the fixed cylinder; a first sleeve arranged in the fixed cylinder, a second sleeve is slidably connected to the outside of the first sleeve, a third sleeve is slidably connected to the outside of the second sleeve, and the third sleeve, the second sleeve and the first sleeve are all arranged in a stepped shape. The operation of the present invention is simple. With the collaborative design of the handle, the sleeve and the driving plate, the operation difficulty of the surgery can be reduced, the efficiency can be improved, and the anastomosis is accurate and reliable.

A percutaneous bypass method for implanting a bypass graft between two vessels is described. The bypass graft comprises a first part and a second part, each having a tubular shape and comprising respective lumens. The method comprises the step of inserting a second sheath, from the outside to the inside of a bypass portion of the first part, through a puncture therein, and retracting the second sheath so as to deploy and implant a hook portion of the second part into the second vessel, and deploy a bypass portion of the second part outside the second vessel, from the second vessel to the first part, and within the lumen of the first part.

This invention relates to the cardiovascular field. Specifically, it relates to the application of ANGPTL2 protein in the treatment and assessment of predicting occlusion after coronary artery bypass grafting (CABG). The biomarker of this invention can accurately target treatment and predict the risk of long-term occlusion of the venous graft after CABG.
