Abstract

The invention provides an intracavity plugging device, the intracavity plugging device comprises a net-shaped framework which is of a hollow structure and comprises two end faces and a side face connected between the two end faces; a flow choking film formed on the net-shaped framework, wherein the flow choking film comprises two end faces and a side face connected between the two end faces; and a plugging promoting piece formed on the surface of the intracavity plugging device; wherein the side face of the net-shaped framework and / or the side face of the flow blocking film are / is a concave-convex surface. The intracavitary plugging device is small in size after being compressed, can be quickly released to plug a false cavity, and can promote thrombosis of the false cavity.

Description

technical field [0001] The present application relates to a medical device, in particular to an intracavity occluder. Background technique [0002] Intervention therapy is an emerging treatment method between surgery and medical treatment, including endovascular intervention and non-vascular intervention. To put it simply, interventional therapy is to make a small channel with a diameter of a few millimeters on the blood vessel or skin without exposing the lesion, or through the original pipeline of the human body, under the guidance of imaging equipment (angiography machine, fluoroscopy machine, etc.) The least invasive treatment method for local treatment of lesions. Interventional therapy has the advantages of less trauma, simplicity, safety, effectiveness, fewer complications, and significantly shortened hospital stay. [0003] As an implant for interventional therapy, the occlusion device can be used to occlude defect openings, or tissue breaches, lumens, and organ pa...
