Abstract

The present invention relates to a cardiac atrial septal defect blocker for repairing defects of atrial septal defect by use of microtraumatic surgery for surgical department and to a method for manufacturing the same. A double sealed screen body provided with membrane filler comprises a conveyance surface, a concave joint portion and an occluding surface. Elastic secure members mounted with a guiding wire are arranged respectively in the center of transfer surface and blockage surface. By employing the technical scheme, the blocker shape is modified, the transfer screw is removed, conduit guiding wire is employed for conveyance, the occluding surface and conveyance surface are made into flat surfaces and the weight of the occluder is reduced. The occluder has a simple structure and reasonable design, in addition the conveyance procedure is simplified and the cost is lowered.

Description

technical field [0001] The present invention relates to an occluder for treating heart diseases and a manufacturing method thereof, more specifically to a special-purpose cardiac atrial septal defect repaired by minimally invasive surgery under the action of a thoracoscope Inventions concerning occluders and methods of manufacture thereof. Background technique [0002] At present, the repair device used in the treatment of atrial septal defect (ASD) in the world and at home is provided with a coupling nut at the end, and the delivery head is connected with a flexible shaft. The leg artery passes through a long path under the action of X-rays. Delivered to the cardiac focus area. With the development of medical technology, some doctors use cardiac surgery puncture to directly puncture and deliver an atrial septal defect (ASD) occluder at the thoracic anastomosis near the heart. It can accurately deliver the occluder to the lesion area. But this kind of treatment scheme tha...
