An intravascular stent (100 200 300) comprises a matrix with a hollowed out area and at least one development structure (103 201 301). Each development structure (103 201 301) comprises a fixed body and a development material (105 208 307) filled in the fixed body. The fixed body is connected to the matrix and is at least partially disposed in the hollowed out area. An envelope enclosed area of all the development materials (105 208 307) in each development structure (103 201 301) is less than or equal to 2 mm2 and a sum of effective areas of all the development materials (105 208 307) in each development structure (103 201 301) is greater than or equal to 0.15 mm2 wherein a ratio of the sum of the effective materials to the envelope enclosed area is greater than or equal to 1:5. The development structure (103 201 301) has a desirable development effect and basically does not affect a pressed holding diameter of the intravascular stent (100 200 300).
