Abstract: The study on artificial blood vessel mainly takes four aspects into consideration, namely the material, structure design, manufacturing of fundamental elements and relevant post-processing method. The manufacturing of fundamental elements and the development of relevant knitting equipment are essential for producing artificial blood vessels. This paper analyzed and compared several kinds of manufacturing methods and relevant knitting equipment for making fundamental elements of artificial blood vessels. In view of the effect of clinical application, artificial blood vessels manufactured by warp knitting machines have been widely applied in actual clinics. Besides, this paper also introduced the products of two domestic artificial blood vessel producers, analyzed their structural characteristics and displayed some physical samples of artificial blood vessel.
