Document Type and Number:
WIPO Patent Application WO/2023/035767
Kind Code:
A1
Abstract:
A 3D multi-branch bionic stent, a preparation method therefor and an application thereof. The 3D multi-branch bionic stent comprises: a main fiber tube, one end of the main fiber tube being connected to at least two primary branch fiber tubes, and the end of each primary branch fiber tube being connected to a secondary branch fiber tube; the cross-sectional area of the main fiber tube is equivalent to the sum of the cross-sectional areas of all the primary branch fiber tubes connected thereto; and the tube wall of the main fiber tube, the tube walls of the primary branch fiber tubes and the tube walls of the secondary branch fiber tubes all have pore structures. The 3D multi-branch bionic stent can provide effective mechanical support for defective tissues, and an interconnected network framework thereof facilitates cellular directional arrangement, osmotic growth, and blood vessel and nerve growth, and also facilitates the transfer of nutritional substances and metabolic waste. The stent has low production costs and high production operability, and is highly flexible.
