Endovascular stent insertion methods are provided. In one embodiment for end-to-side anastomosis the method includes disposing an endovascular stent in a transparent sheath; inserting a guide wire through a guide needle into first and second blood vessels; sliding the endovascular stent into both the first and second blood vessels along the guide wire and the guide needle to dispose in a position between spaced first and second blood vessels; and pulling the sheath when an intermediate annular marker band of the endovascular stent seen through the transparent sheath is substantially disposed between the first blood vessel and the second blood vessel to release the endovascular stent so that the endovascular stent is adapted to expand to securely hold the facing ends of the first and second blood vessel together.
