As viewed in figures 5-8, the concrete operation step that induction system conveying overlay film frame is applied at the arch of aorta：
First, according to by the technologies such as angiogram, CTA determine the arch of aorta be respectively segmented diameter (including aorta ascendens end,
Innominate artery (truncus brachiocephalicus) is to left neck block, left neck always to left subclavian artery section, descending aorta front end), innominate artery (head arm
It is dry), left common carotid artery, the diameter of left subclavian artery, the spacing between contiguous branch.According to master at each branch's diameter and its place
Spacing between the diameter of artery 160, contiguous branch, the diameter of selection branch stent 500 is more than or equal to respective branches blood vessel 5%-
30%, the diameter 10%-30% of sustainer 160 where the diameter correspondence of main body rack 400, the length selection of main body rack 400 is small
In equal to the minimum spacing between contiguous branch blood vessel 170, it is coincide absolutely so as to realize that less bifurcated stent specification can be met
The anatomical structure of the Most patients arch of aorta.
After surgical stent is chosen, patient is under general anesthesia, lung ventilator assisted ventilation, patient lies supine position, at femoral artery
Puncture is made a gift to someone big sheath, is made a gift to someone stiffened seal wire and conventional guidewire by big sheath, stiffened seal wire is made a gift to someone to aorta ascendens 160, conventional
Seal wire is made a gift to someone under left clavicle, and stiffened seal wire and conventional guidewire end are then filled in into the support that arch of aorta end is placed in selection respectively
The first guidewire lumen 100 and the second guidewire lumen 200 of induction system, then send into the delivery system for being loaded with overlay film system along double seal wires
System.
System front end to be conveyed is arrived at after descending aorta 160, drop back induction system outer tube 600, make branch stent 500 with
Main body rack 400 can voluntarily deploy angled.Continue to move under promoting induction system to branch stent 500 into left clavicle
With vascular bifurcation everywhere in same position at arteries and veins and graft bifurcation, fixed induction system, the first fixing component of post-tensioning 801 makes master
Body support frame 400 deploys, after main body rack 400 deploys, then the second fixing component of post-tensioning 802, deploys branch stent 500.So
After withdraw from induction system, then conventional guidewire of dropping back makes a gift to someone conventional guidewire left common carotid artery, left neck summation of being made a gift to someone successively with method
Branch stent at truncus brachiocephalicus.After overlay film frame whole release is finished, using angiography catheter radiography, determine overlay film frame position and open
Degree is put, decides whether to expand after carrying out according to situation.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
The present invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part or all technical characteristic are entered
Row equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technology
The scope of scheme.
