Abstract:
An artificial blood vessel with stent for use in clinical operation of Stanford types A aortic dissection, which can simplify treatment and reduce risk of surgery. The artificial blood vessel has a wall thickness of 0.30-0.35 mm and a length of 15-20 cm. The proximal portion of it refers to a portion with about 5-10 cm in length and contains just the polyester artificial blood vessel, the distal portion of it refers to a portion with about 8-10 cm in length and contains the polyester artificial blood vessel and a plural of “W” shaped titanium-nickel alloy stents with self-expanding function fixed inside the blood vessel, and the blood vessel and the stents are fixed together by stitching. The artificial blood vessel with stent has a diameter of 24-30 mm. When used in a surgery, different diameters are selected according to the internal diameters of aortic artery of different patients.

Claim (Index 1):
An artificial blood vessel with stent, having a length of about 15-20 cm, a diameter of 24-30 mm, and a wall thickness of 0.30-0.35 mm, wherein the artificial blood vessel comprises:\n a proximal artificial blood vessel portion, having a length of about 5-10 cm and made of polyester; and a distal artificial blood vessel portion, having a length of longer than 8 cm and less than 10 cm and made of a polyester surface and a plurality of \u201cW\u201d shaped titanium-nickel alloy stents with self-expanding function fixed inside the polyester surface, wherein the polyester surface and the stents are stitched together, and the diameter of the artificial blood vessel with stent is selected based on internal diameters of aortic artery of different patients.
