BIODEGRADABLE CROSS-LINKED POLYMER, VASCULAR STENT AND MANUFACTURING METHODS THEREFOR |
摘要 |
The present invention relates to the field of medical instruments. Specifically, a biodegradable cross-linked polymer and a manufacturing method therefor are provided. The cross-linked polymer is a cross-linked polymer network that is obtained as follows: the terminal end of a degradable polymer pre-polymer body having two or more arms connects with a cross-linkable active group, and then thermal polymerization and/or photo irradiation processing is performed thereon. The cross-linked polymer has an elastic modulus of between 10 MPa and 4,500 MPa, and a degradation rate of between 3 months and 36 months. A degradable vascular stent and a preparation method therefor are also provided. The vascular stent is formed by laser cutting of polymeric tubing having a three-dimensional cross-linked network structure. The vascular stent has ample mechanical strength, a high elastic modulus at body temperature, and a regulatable degradation rate. |
