摘要： A stent (1100, 1110) and a drug delivery device (1000, 1001) are disclosed. The stent (1100, 1110) includes a tubular body (300, 350) provided at its one end with a connecting structure (400, 420, 450, 460, 1111) for connection with a recovery mechanism (650). A drug is applied on the surface of the tubular body (300, 350). The drug delivery device (1000, 1001) includes such a stent (1100, 1110) and a recovery mechanism (650). The recovery mechanism (650) includes a sheath (610, 1220, 1221) and a recovery wire (800, 850, 860, 1210, 1230) that passes through the sheath (610, 1220, 1221) and has one end connected to the connecting structure (400, 420, 450, 460, 1111) of the stent (1100, 1110). The sheath (610, 1220, 1221) is adapted to receive the stent (1100, 1110) when it is in a contracted configuration. The stent (1100, 1110) is capable of fast drug release and recoverable.
