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.

Abstract: A method of formulating a strong oxidizing solution comprising formulating a strong oxidizing solution having from about 2 to about 5 percent PDSA with concentrated sulfuric acid in the ratio of from about 1:8 to about 1:20 parts by volume and storing the strong oxidizing solution in a container having a space over the solution containing one of a vacuum or a non-oxidizing atmosphere inert to the oxidizing solution. The amount of PDSA is preferably about 4 percent by volume and the ratio is preferably about 1:10 parts by volume. The space over the strong oxidizing solution is preferably a vacuum or substantially all nitrogen.
