| 摘要 |
The invention relates to an expandable system comprising a catheter balloon and a crimped stent. Said system combines fast release kinetics of one active substance and slow release kinetics of a second active substance since the catheter balloon is coated with a first active substance that is suitable for fast release while the stent is coated with a second active substance which is suitable for slow release. In a preferred embodiment, the catheter balloon is coated with a cytotoxic amount of a first active substance while the stent is coated with a cytostatic amount of a second active substance. |
