Abstract

The invention provides a plugging device, which comprises a metal skeleton and a flow resistance film, wherein the metal skeleton comprises a near-end disk surface, a far-end disk surface and a waistpart used for connecting the near-end disk surface with the far-end disk surface; the near-end disk surface and the far-end disk surface are both of a reticular structure weaved by metal wires; the near-end disk surface and the far-end disk surface are independently provided with a puncture hole, and the size of the puncture hole is far greater than the mesh openings of the near-end disk surface and the far-end disk surface; and the flow resistance film is arranged in the near-end disk surface and the far-end disk surface and covers the puncture holes, wherein the material of the flow resistance film is a macromolecule absorbable material. Since the near-end disk surface and the far-end disk surface of the above plugging device are independently provided with the puncture hole, if atrial septum puncture needs to be carried out in the future, a puncture needle can penetrate through the position of a puncture hole, and the interference of the metal skeleton of the plugging device can beeffectively avoided so as to be favorable for successfully carrying out atrial septum puncture surgery in the future.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an occluder. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] A heart defect occluder is an implantable medical device for the treatment of congenital heart defects, usually consisting of a metal mesh skeleton, a flow-blocking membrane and sutures. The metal mesh skeleton is braided by super-elastic nickel-titanium alloy wires to form a structure of two discs and one waist. A block film of polymer material is sewn with sutures in the middle of the two discs and the waist. The occluder is implanted into the patient's body through interventional methods. After a period of time after implantation, the surface of the occluder will endothelialize and grow into one with the surrounding tissue, while the metal mesh skeleton is permanently left on the cardiac septum. [0004] Some ...
