| titleOfInvention | Drug eluting balloon and balloon catheter |
| abstract | Disclosed is a drug eluting balloon for a balloon catheter. The drug eluting balloon comprises a balloon body ( 100 ) and a coating ( 200 ), and the coating ( 200 ) comprises a water-soluble adhesive layer ( 210 ), an isolating layer ( 220 ) and a drug layer ( 230 ) from the inside out. After the drug eluting balloon is pushed to a diseased part, the balloon body ( 100 ) is expanded, and the water-soluble adhesive layer ( 210 ) dissolves due to scouring by a blood flow, such that the isolating layer ( 220 ) and the drug layer ( 230 ) are separated from an outer surface of the balloon body ( 100 ) and adhere to a blood vessel wall. The provision of the isolating layer ( 220 ) can effectively suppress the water-soluble adhesive layer ( 210 ) from removing part of the drug layer ( 230 ) during dissolution, and after the drug layer ( 230 ) adheres to and makes contact with the blood vessel wall, the isolating layer can also reduce the scouring effect on the drug layer ( 230 ) by the blood flow, thereby reducing the loss of drugs, allowing the drugs to be taken in by the blood vessel wall to the greatest extent, greatly improving the utilization rate of the drugs and improving the treatment effect while also preventing toxic and side effects brought about by large doses of the drugs. Moreover, the isolating layer ( 220 ) can also realize the slow release of the drug layer ( 230 ), such that the drug layer ( 230 ) can provide treatment for a long time, and a good treatment effect can be obtained. |
