Filming support

A filming support comprises a supporting structure and a film covering the supporting structure, wherein the film is composed of at least two stacked layers of allogeneic acellular tissue base film, the smooth side of each layer of the base film faces the supporting structure while the rough side faces out; the adjacent two layers of base film are arranged by crossing at a certain angle along a growth direction of a collagen bundle. In the at least two layers of the allogeneic acellular tissue base film, all base film is provided with a plurality of through holes expect for the innermost layer, and the hole diameter increases gradually from the inner layer to the outer layer. The use of the filming support is effective in reducing the formation of thrombus and endotheliosis, in enhancing film strength and reducing the axial tension of the film during the release of the filming support, and in adhering endothelial cells to promote cell differentiation to promote the ingrowth of tissues and vessels, and quickening the endothelialization of lesion areas of arterial aneurysm to give better effect in treating arterial aneurysm.
