Abstract: In the stent for use in the interventional treatment of vascular diseases and in vascular surgery, there is a tubular support structure formed with struts made of a first bioresorbable metallic material that are joined to one another at selective points. The surface of the struts is fully covered by a coating made with a second bioresorbable metallic material. The second metallic material has a lower dissolution rate in the implanted state under physiological conditions in the course of bioresorption, and has a more positive electrode potential compared to the first metallic material.

Abstract: An electrically conductive connection element for a temporary electrically conductive connection to an electrical consumer, in particular an external pacemaker, which is implanted in the living tissue of a patient, may have at least one biocompatible and bioresorbable electrical conductor strand in the form of an individual wire or a multifilament formed by multiple wires. The at least one electrical conductor strand is surrounded by at least one biocompatible and bioresorbable polymer or is embedded in a matrix formed by the polymer.

Abstract: A method for extracting metal and oxygen from powdered metal oxides in electrolytic cell is proposed, the electrolytic cell comprising a container, a cathode, an anode and an oxygen-ion-conducting membrane, the method comprising providing a solid oxygen ion conducting electrolyte powder into a container, providing a feedstock comprising at least one metal oxide in powdered form into the container, applying an electric potential across the cathode and the anode, the cathode being in communication with the electrolyte powder and the anode being in communication with the membrane in communication with the electrolyte powder, such that at least one respective metallic species of the at least one metal oxide is reduced at the cathode and oxygen is oxidized at the anode to form molecular oxygen, wherein the potential across the cathode and the anode is greater than the dissociation potential of the at least one metal oxide and less than the dissociation potential of the solid electrolyte powder and the membrane.
