Claim:
1. An occluder for occluding an opening in a circulatory system, wherein the occluder can be converted from a compact manifestation, extending along a longitudinal axis, into an expanded manifestation, wherein the occluder has a first expansion unit and a second expansion unit, which are configured to rest against opposite sides of the opening in the expanded manifestation, and wherein the occluder furthermore has a first coupling part and a second coupling part, wherein the first coupling part and the second coupling part are configured to be brought together at a site of the opening to be occluded, wherein the first coupling part forms a distal end of the occluder and the second coupling part forms a proximal end of the occluder, wherein the first coupling part has a region that at least in part runs between the first and the second expansion unit in the expanded manifestation, wherein the region is stretchable along the longitudinal axis, wherein the first expansion unit is attached to the first coupling part and the second expansion unit is attached to the second coupling part, wherein the first expansion unit and the second expansion unit are formed by wires running between the first and the second coupling parts, each of said wires comprising a first end and a second end, the first end being held in or attached to the first coupling part and the second end being held in or attached to the second coupling part, and wherein the first expansion unit and the second expansion unit are brought from the compact manifestation into the expanded manifestation by bringing the first coupling part and the second coupling part together, and wherein a portion of the first coupling part is insertable into a portion of the second coupling part or wherein a portion of the second coupling part is insertable into a portion of the first coupling part to fix the occluder in the expanded manifestation thereof.
