Occluder for occluding an atrial appendage and production process therefor

摘要

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.

1. An atrial appendage occlusion device comprising a mesh or braiding of at least one wire or thread, wherein 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 anchoring in an atrial appendage of the left or right atrium of a heart, comprising
a proximal retention region at a proximal end of the occlusion device and formed from said mesh or braiding; a distal retention region; and a central region between said proximal retention region and said distal retention region; wherein the occlusion device has a closed distal end without a hub for said wire or thread, and wherein said proximal retention region of said occlusion device is of elongate spherical shape and at least partly hollow, and wherein said distal retention region comprises a distal anchoring element integrally made of the same mesh or braiding as the hollow elongate spherical proximal retention region, and wherein said device comprises at least one further distal anchoring element integrally made of the same mesh or braiding as the proximal and distal retention region.
