Abstract

The invention discloses a biodegradable magnetically controlled PVA micro-motor support, a preparation method and an application thereof. The magnetically controlled PVA material is obtained by mixing and crosslinking polyvinyl alcohol, magnetic particles, a crosslinking agent, and water. The vascular stent prepared by using the material in the present invention can use ultrasound to trigger shape memory, and cooperate with the motion performance of the magnetic drive motor , can simplify the adjustment process of the material formula and the implantation process, control the movement of the stent in the body to reach the target position, without the need for fixed-point implantation, further reduce the invasiveness and implantation risk, and more meet the actual application requirements.

Description

technical field

[0001] The invention belongs to the field of biological materials, and in particular relates to a biodegradable magnetron PVA micromotor support and a preparation method and application thereof. Background technique

[0002] Micromotor is an artificial power device with excellent motion performance and precise navigation performance, and has broad application prospects in the field of biomedicine. Biocompatibility has important research significance.

[0003] Vascular stent implantation is an effective medical intervention for treating diseases related to vascular stenosis. However, in the prior art, vascular stents prepared from traditional materials have problems such as insufficient biocompatibility and the need to introduce additional shape expansion devices. The accuracy of implantation requires highly invasive treatment methods, and the existence of these problems can easily lead to vascular restenosis and arterial injury, thereby reducing the effectiv...
