Abstract:
1. A method of implanting an endovascular stent into a human body for end-to-end anastomosis, comprising the steps of: locating first and second blood vessels to be connected together as target vessels; performing a blood control on each of the first and second blood vessels; inserting a guide needle into each of the first and second blood vessels; injecting a diluted medicine of heparin into each of the first and second blood vessels for expansion; using a C-shaped vessel sizer to measure the diameter of each of the first and second blood vessels; taking the measurement result as a basis for selecting a predetermined endovascular stent having a waterproof membrane on its inner surface, a front section, a rear section, and an intermediate annular marker band formed between the front section and the rear section; disposing the predetermined endovascular stent in a transparent sheath; inserting a guide wire through a guide needle into both the first and second blood vessels; sliding the predetermined endovascular stent into both the first and second blood vessels along the guide wire and the guide needle to dispose in a position between the spaced first and second blood vessels; and pulling the sheath when the marker band of the predetermined endovascular stent seen through the transparent sheath is disposed between the first blood vessel and the second blood vessel to release the predetermined endovascular stent so that the predetermined endovascular stent is adapted to expand to securely fasten the facing ends of the first and second blood vessel together.
