Abstract
The present invention is applicable to the technical field of interventional medical devices and provides an occluder and an occluding system having the occluder. The occluder includes a woven main body, where the woven main body is formed by shaping a woven mesh tube formed by weaving woven wires having a shape memory function. The woven main body is provided with a shrinkage deformation resistance reduction structure that reduces a resistance of the woven main body entering a pipe; the shrinkage deformation resistance reduction structure reduces the resistance of the woven main body entering the pipe by reducing the contact area between the woven main body and an inner wall of the pipe during radial shrinkage deformation of the woven main body entering the pipe so that the occluder may smoothly and successfully enter a pipe of a delivery sheath, thereby greatly reducing the operation difficulty and risk caused by unsmooth entry of the occluder into the delivery sheath.
