Production process of an occluder for occluding an atrial appendage

摘要

An occlusion device (1) and a production process for it are described. The occlusion device consists of a mesh or braiding (7) of at least one wire or thread (7a), wherein the occlusion device (1) 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 (10) of the left or right atrium of a heart. The occlusion device (1) comprises a proximal retention region (2) on a proximal end (20) of the occlusion device (1); a distal retention region (3); and a central region (5) between the proximal retention region (2) and said distal retention region (3); and wherein the occlusion device (1) has a closed distal end (21) without a holder, and wherein the occlusion device (1) is at least partly of essentially spherical form, and hollow.
