Abstract
An occluder includes a first occluder disc, a second occluder disc, a waist portion connecting the first occluder disc and the second occluder disc, and at least one soft and fibrous strand bundle structure. The strand bundle structure is disposed on at least one of a disc surface of the first occluder disc and a disc surface of the second occluder disc, the two disc surfaces faces each other, and the strand bundle structure is disposed near the waist portion. By disposing the strand bundle structure to be immediately adjacent to the waist portion, a defect opening can be occluded after implantation, thereby effectively blocking blood from flowing from one side of the defect to the other side thereof, and preventing a shunt from being formed.
