The invention discloses a biodegradable magnetic control PVA micromotor bracket and a preparation method and application thereof. The magnetic control PVA material is obtained by mixing and crosslinking polyvinyl alcohol, magnetic particles, a crosslinking agent and water, the intravascular stent prepared by using the material can adopt ultrasonic trigger shape memory and is matched with the motion performance of a magnetic drive motor, the adjustment process and the implantation process of a material formula can be simplified, the intravascular stent is controlled to move in vivo to reach a target position, fixed-point implantation is not needed, the invasiveness and the implantation risk are further reduced, and the practical application requirements are met better. |
