Biodegradable double stent |
摘要 |
A biodegradable double stent is used for various organs such as a biliary tract, an esophagus, an airway and a ureter. A biodegradable stent having a hollow cylindrical body woven out of a separate wire made of biodegradable polymer so as to have a plurality of rhombic spaces is fixed to an intermediate portion of a primary stent having a cylindrical body. When administered into the organ, the biodegradable stent has its original function of expanding the organ, and is firmly supported in the inner wall of a narrowed passage of the organ by pressurizing the inner wall of the narrowed passage of the organ. After a predetermined time period has elapsed, the biodegradable stent is gradually degraded away by bodily fluids, thereby enabling the primary stent to be easily removed from the organ. |
