Abstract
The present application discloses an occluder, including a distal disc, a waist portion, and a proximal disc which are formed in sequence. The proximal disc includes a proximal disc surface. A proximal bending area is formed at a circumference of the proximal disc surface and bent towards the distal disc, where the proximal bending area surrounds an edge of the distal disc, and a stabilizing wire is further threaded through a free end of the proximal bending area and may tighten the free end of the proximal bending area towards the waist portion.

An occluder, comprising a distal disc, a waist portion and a proximal disc formed in sequence, wherein:
- the waist portion connects the proximal disk to the distal disk;
- the proximal disc comprises a proximal disc surface,
- a proximal bending area bent toward the distal disc is formed at a circumference of the proximal disc surface,
- the proximal bending area surrounds an edge of the distal disc, and
- a stabilizing wire comprising one or more loops is threaded through a free end of the proximal bending area and the stabilizing wire is able to tighten the free end of the proximal bending area towards the waist portion.
