一种个性化聚合物支架及其制备方法和用途技术

一种个性化聚合物支架及其制法和用途。支架具有与待使用部位内腔或腔外轮廓的形状和尺寸相匹配外形和尺寸，并且具有由聚合物细丝按照预先设计的图案沉积而构成的支架结构，支架沿支架的长度方向具有至少一种变化的直径。根据待使用部位的医学影像扫描的内腔或腔外轮廓的数据制备出与待使用部位内腔或腔外轮廓的形状和尺寸相匹配的空心或实心的个性化支架模具；将模具套在四轴快速成型系统的第四轴上或直接作为第四轴用于接收聚合物，制备出个性化的支架产品。支架的形状和尺寸与待使用部位相匹配，支架的长度、角度和曲率更加适应待使用部位的构造形式，能够满足待使用部位的特殊要求，支架的贴壁性能和治疗效果得以改善。

Personalized polymer stent and preparation method and use thereof

A personalized polymer stent and its preparation and application. The bracket has a shape and size matching the shape and size of the inner cavity or outer contour of the used part, and has a scaffold structure composed of a polymer filaments deposited according to a pre designed pattern. The support has at least one change in diameter along the length direction of the bracket. A hollow or solid scaffold mold that matches the shape and size of the inner cavity or outer contours of the area to be used is prepared according to the data of the inner cavity or outer contours of the medical image to be used. The mold is placed on the fourth axis of the four axis rapid prototyping system or directly as the fourth axis for receiving the polymer. Personalized scaffolding products are prepared. The shape and size of the scaffold match the area to be used. The length, angle and curvature of the bracket are more suitable for the structure of the parts to be used. It can meet the special requirements of the parts to be used, and the wall performance and treatment effect of the support can be improved.
