Abstract: A catheter includes a medical bypass implant having a first end, a second end, and a body forming a flow lumen. A catheter shaft defines an inner lumen and a distal end. The inner lumen receives the medical implant in a delivery state such that the first end is arranged near to the distal end and the second end is arranged proximally from the first end. The catheter shaft is moved towards a vessel wall to place the first end on the vessel wall. An actuating catheter is received in the inner lumen. A tip thereof is operatively connected to the second end. The actuating catheter moves the second end towards the first end. The tip is configured to penetrate the vessel wall and to move the second end of the medical implant through the vessel wall.

Abstract: A method for preparing a biodegradable tissue includes providing one or more native biological tissue(s) or one or more decellularized biological tissue(s). The method includes structurally stabilizing the one or more native biological tissue(s) or the one or more decellularized biological tissue(s) with a tissue water replacement material to obtain a structurally stabilized tissue and providing one or more permeable material layer(s). The method includes placing the structurally stabilized tissue on the one or more permeable material layer(s) or between two of the one or more permeable material layers and drying the structurally stabilized tissue while applying a pressure to the structurally stabilized tissue to obtain a dried biodegradable tissue.

Abstract: An electrolyte for electropolishing metal surfaces, in particular workpieces, in particular made of titanium or titanium alloys such as nitinol. The electrolyte composition includes methanesulfonic acid and more than one polyhydric alcohol. The content of methanesulfonic acid is less than 15 vol %, the polyhydric alcohols having at least one diol and at least one polyalcohol.
