| description | A blood vessel connecting device and a preparation method therefor, the blood vessel connecting device comprising a nickel-titanium woven stent (3) and a connecting pipe (1), wherein the nickel-titanium woven stent (3) and the connecting pipe are each covered with a polytetrafluoroethylene coating film (2) to make the device an integrated structure. A film-coated stent of the blood vessel connecting device may be released into a collateral blood vessel (a head arm trunk artery, a left common carotid artery, or a left subclavian artery) of an aortic arch, and the connecting pipe (1) is used for connecting a collateral artificial blood vessel of a four-branch artificial blood vessel, so that the collateral artificial blood vessel of the four-branch artificial blood vessel and the aortic collateral blood vessel can be suture-free, thereby reducing the time needed for an aortic arch replacement surgery.
