摘要:
A degradable occluder, which comprises a first disc-shaped mesh (10), a tubular mesh (30), and a second disc-shaped mesh (20) connected in series. The tubular mesh (30) is connected respectively at either extremity thereof to the first disc-shaped mesh (10) and the second disc-shaped mesh (20). The first disc-shaped mesh (10), the tubular mesh (30), and the second disc-shaped mesh (20) are integrally formed. The second disc-shaped mesh (20) is provided with a connecting element (40) used for collapsing the mesh surface. The connecting element (40) is formed by hot melting the mesh body of the second disc-shaped mesh (20). The materials of the first disc-shaped mesh (10), the tubular mesh (30), the second disc-shaped mesh (20), and the connecting element (40) are degradable materials. The collapsible structure of a drawstring of the occluder increases the support and resilience of the occluder, reduces manufacturing difficulty, not only allows degradable wires composing the disc-shaped meshes (10 and 20) to be firmly connected together, but also allows the connecting element (40) to be firmly connected together with the degradable wires composing the disc-shaped meshes (10 and 20), thus not being prone to falling off.Un obturateur dégradable, qui comprend un premier maillage en forme de disque (10), un maillage tubulaire (30), et un second maillage en forme de disque (20) reliés en série. Le maillage tubulaire (30) est relié respectivement à chaque extrémité au premier maillage en forme de disque (10) et au second maillage en forme de disque (20). Le premier maillage en forme de disque (10), le maillage tubulaire (30), et le second maillage en forme de disque (20) sont formés de façon intégrée. Le second maillage en forme de disque (20) est pourvu d'un élément de liaison (40) utilisé pour plier la surface maillée. L'élément de liaison (40) est formé par fusion à chaud du corps maillé du second maillage en forme de disque (20). Le matériau de la première maille en for
