Absorbable occluder

Abstract

The application relates to an absorbable occlusion device, which comprises an occlusion net and a flow blocking structure arranged in the cavity of the occlusion net, the flow blocking structure comprises a first flow blocking part and a second flow blocking part arranged in sequence along the axial direction; the first flow blocking part comprises a first radial flow blocking film, a first circumferential flow blocking film and a second radial flow blocking film arranged in sequence along the axial direction, the first circumferential flow blocking film extends along the circumferential direction to form a first tubular structure, the axial two ends of the first tubular structure are both provided with openings, the second radial flow blocking film covers the opening of the first tubular structure which is closer to the second occlusion disc, and a spacing section exists between the second radial flow blocking film and the second flow blocking part along the axial direction, and no flow blocking film exists in the spacing section. The occlusion device has good occlusion effect, and can effectively reduce the problem that the occlusion disc is not shaped well in the operation due to the fact that the flow blocking film is difficult to deform along with the occlusion net.
