Abstract

An occlusion device and a production process for it are described. The occlusion device consists of a mesh or braiding of at least one wire or thread wherein the occlusion device has been given a suitable design using a reshaping and/or heat-treatment process, is self-expandable, and is configured for secure anchoring in an atrial appendage of the left or right atrium of a heart. The occlusion device comprises a proximal retention region on a proximal end of the occlusion device a distal retention region and a central region between the proximal retention region and said distal retention region and wherein the occlusion device has a closed distal end without a holder, and wherein the occlusion device is at least partly of essentially spherical form, and hollow.
