Kind of a cheat there with that last word, but the dCell Vascular Patch made by Tissue Regenix (York, UK) has received CE mark approval for sales in Europe.
The dCELL® Vascular Patch is a sterile, non-cellular biological scaffold manufactured to the highest quality and safety standards from porcine pericardium which is intended to be permanently implanted into the human body for vascular repair.
This product, and products like it, takes biological material from animals (pigs in this case) and through various processes strips out the material the human body would mount an immunological attack against while leaving the underlying structure, allowing grafts of things like heart valves without requiring immuno-suppresive drugs.
