Occluder for occluding an atrial appendage

摘要

An atrial appendage occlusion device (1) comprises mesh or braiding (7) of at least one wire or thread (7a), where the occlusion device has been given a shape using a reshaping and/or heat-treatment process, and is self-expandable, as well as configured for safe anchoring in an atrial appendage (10) of the left or right atrium of a heart, comprising proximal retention region (2) at proximal end (20) of the occlusion device; a distal retention region (3); and a central region (5) between the proximal retention region and the distal retention region. An atrial appendage occlusion device (1) comprises mesh or braiding (7) of at least one wire or thread (7a), where the occlusion device has been given a shape using a reshaping and/or heat-treatment process, and is self-expandable, as well as configured for safe anchoring in an atrial appendage (10) of the left or right atrium of a heart, comprising proximal retention region (2) at proximal end (20) of the occlusion device; a distal retention region (3); and a central region (5) between the proximal retention region and the distal retention region; where the occlusion device has a closed distal end (21) without a hub for the wire or thread, and where the proximal retention region is of elongate spherical shape and at least partly hollow, and where the distal retention region comprises a distal anchoring element integrally made of the same mesh or braiding as the hollow elongate spherical proximal retention region. An independent claim is included for production of an atrial appendage occlusion device, where a spherical hollow mesh or braiding is produced in such a way that thin wires or threads which constitute the finished mesh or braiding are interwoven in the formation of the spherical hollow mesh or braiding at the distal end (21) of the mesh or braiding, so that a distal retention region (3) has a closed shape to the distal end (21).
