A method of implanting an aortic stent comprising steps of: putting a main tube on a metal guide wire; moving the main tube along the metal guide wire to the descending aorta, the main tube is constrained by a first cover, and first and second tube bifurcations are branched from the main section; removing the first cover; inserting a second and third metal guide wire through the first tube bifurcation into the ascending aorta and branchiocephalic artery respectively; a first and a second tube branch moving into the ascending aorta and the branchiocephalic artery respectively; inserting a fourth and fifth metal guide wire through the first tube bifurcation into the ascending aorta and branchiocephalic artery respectively; a third and a fourth tube branch moving into left common carotid artery and the left subclavian artery respectively; removing a second cover constraining said tube branches.

A tracheotomy tube set is provided with a tracheotomy tube including: a cannula including a connecting member at a proximal end and a bellows member joining to the connecting member, a balloon cuff formed proximal to a distal end of the cannula, a first wing extending from one side of one end of the balloon cuff, a second wing extending from the other side of one end of the balloon cuff, a first wedge balloon formed between the first wing and an insertion section between the balloon cuff and the distal end of the cannula, an opposite second wedge balloon formed between the second wing and the insertion section, and a line having one end communicating with both the first and second wedge balloons; and a fixation device including a split flange, a hole through the split flange, and two slots formed at both sides of the fixation device respectively.

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.
