Abstract
The invention discloses a double-layer small-caliber nanofiber tissue engineering blood vessel stent and a preparation method thereof. The double-layer small-caliber nanofiber tissue engineering bloodvessel stent comprises an inner layer of a tissue engineering blood vessel stent and an outer layer of the tissue engineering blood vessel stent, wherein the inner layer of the tissue engineering blood vessel stent and the outer layer of the tissue engineering blood vessel stent are sequentially electrospun to obtain a core-spun yarn on the core yarn, and after the electrospinning is completed, the core yarn of the core-spun yarn is extracted to obtain a tissue engineering blood vessel stent. As the blood vessel tissue engineer stent material with micro and small caliber has a multi-layer structure and composition of the bionic natural blood vessel to a certain extent, the blood vessel tissue engineer stent material has good biocompatibility, is not easy to generate thrombus and has sufficient viscoelasticity so that the blood vessel tissue engineering stent material can withstand the pressure in the blood vessel for a long time.
