Plugging device and plugging system

The invention is suitable for the technical field of interventional medical instruments, and provides a plugging device and a plugging system with the plugging device, the plugging device comprises a weaving main body, the weaving main body is formed by shaping a weaving net pipe formed by weaving weaving wires with a shape memory function, a contraction deformation resistance reducing structure for reducing the resistance of the woven main body entering the pipeline is arranged on the woven main body; according to the contraction deformation resistance reduction structure, when the woven body enters the pipeline and generates radial contraction deformation, the contact area of the woven body and the inner wall of the pipeline is reduced, so that the pipe entering resistance of the woven body is reduced, and therefore the plugging device can enter the conveying sheath pipe smoothly; and the operation difficulty and risk caused by unsmooth sheathing of the plugging device can be greatly reduced. 本发明适用于介入医疗器械技术
