Title
(EN) Synthetic polymer and natural extracellular matrix composite material, artificial blood vessel and preparation method thereof
(ZH) 一种合成高分子与天然细胞外基质复合材料、人工血管及其制备方法
Abstract
(EN)
The invention relates to a degradable synthetic polymer and natural extracellular matrix composite material, an artificial blood vessel and a preparation method thereof. Degradable synthetic polymer components during preparation can be selected from one or more materials to perform proportioning; support materials with different fiber diameters, different fiber arrangement, different apertures anddifferent pore structures can be prepared through various technologies such as electrospinning, wet spinning, melt spinning, 3D printing, pouring, phase separation and particle leaching; and naturalextracellular matrix components are wide in sources, can be selected from vascular tissues (such as the arteries and veins of pigs and cows) of different species of animal sources or the vascular tissues (such as umbilical cords) of human donors, and can flexibly adjust the components and content thereof according to needs. The composite material and the artificial blood vessel prepared by the preparation technology can have good mechanical properties, controllable space structures, appropriate degradation velocity and excellent biocompatibility and biological induction activity; and the composite material, the artificial blood vessel and the preparation method are simple in preparation technology, high in controllability, mild in condition and suitable for large-scale industrial production.
