  • Tubular vascular graft and the preparation thereof
    Patent number: 9820846
    Abstract: The present invention provides a reparation method of a tubular vascular graft, (a) immersing a tubular scaffold in a first light sensitivity gelatin solution, and irradiate the tubular scaffold by a first time period, to let surface of the tubular scaffold form a base layer; (b) immersing the tubular scaffold of the step (a) in a chitin gelatin solution, when the surface of the base layer form a film, then immersing the tubular scaffold into a sodium hydroxide solution to generate a middle layer of the surface of the base layer; (c) immersing the tubular scaffold of the step (b) in a second light sensitivity gelatin solution, wherein the second light sensitivity gelatin solution comprises a cell, the tubular scaffold is irradiated by a second time period to form a surface layer of the middle layer; (d) until the cell forms a tubular structure of the surface layer by the cell in the tubular scaffold of the step (c), heating the tubular scaffold by a temperature to solve the base layer into a solution, pulling
