Interventional stent and interventional prosthesis

The invention discloses an interventional stent and an interventional prosthesis. The interventional stent comprises a connecting covering film, and a tubular connecting cavity is defined by the connecting covering film. The supporting frameworks are fixed to the wall face of the connecting covering film and are arranged in the axial direction of the connecting covering film; the windowing structure is arranged on the connecting covering film, and the windowing structure communicates with the connecting cavity; at least part of the windowing structure and at least one supporting framework are integrally arranged, it is guaranteed that each supporting framework connected to the covering film is of an independent closed-loop structure, and the radial supporting force of the windowing structure can be improved; each supporting skeleton is of an independent closed-loop structure, and the radial supporting force formed by the supporting skeletons can slow down the situation that the radial size of the intervention
