titleOfInvention | A kind of degradable tubing of multilayer, bracket and preparation method thereof |
abstract | The invention discloses a kind of degradable tubing of multilayer, bracket and preparation method thereof, the tubing is in a tubular form and including at least two layers, wherein, the tubing different layers are made of biodegradable polymer material, the tubing includes at least internal layer and outer layer, and the molecular weight of the material of the outer layer is higher than the molecular weight of the material of the internal layer;The biodegradable stent is cut by the degradable tubing of multilayer, and degradation rate of the degradable tubing from internal layer to outer layer is sequentially reduced, and outer layer selects the material that mechanical strength is high, degradation time is long, can play sufficiently long effective support blood vessels time;Internal layer selects good biocompatibility, the compatibility of bracket and blood can be improved in the short material of degradation time, internal layer take the lead in degradation, reduce bracket a large amount of degradation fragments for generating in integrally disintegration, while with the degradation of internal layer, the Lumen Area at vascular lesion position will be gradually increased. |
