Abstract： |
The present invention relates to the preparation of biodegradable, X-ray visible, anti-infectious, antitumor, anti-fibrosis and anti-calculus multi-layer composite medicine composite polymer biliary rack. Several kinds of degradable polymer material are used in preparing the multi-layer rack, and the degradation speed gets faster from inside to outside of the rack cavity. During the degradation, the rack falls down from inside to outside, and the induced gall silt and gallstone fall from the rack to drain into intestinal tract without forming large gallstone to prevent re-stenosis and infection. |
