23 Jul Method and system for forming intravascular stent through fused direct writing electrostatic spinning
Abstract
The invention relates to a method and a system for forming an intravascular stent through fused direct writing electrostatic spinning and belongs to the fields of tissue engineering and vascular tissue repair. The method comprises the following step: directly forming the intravascular stent with micron-scale spinning fibers and micron-scale pore diameter by utilizing artificially synthesized high polymer materials. During forming, the intravascular stent with a three-dimensional through hole is electrically spun through direct writing at a spatial specific position under the action of a high-voltage electric field at the environmental temperature of 60+/-5 DEG C through control of a computer system according to the designed stent structure and forming path; and meanwhile, the direct writing technology is introduced, a deposition path can be controlled, and the stent can be degraded and controlled by utilizing the material characteristics. According to the forming method and the forming system, the forming quality of the intravascular stent can be guaranteed, and the intravascular stent has obvious advantages of subsequently culturing stent cells and repairing blood vessels due to human implantation.
