The tricuspid valve will serve not only as a way of replacing tricuspid valves that are a problem for patients, but a platform for other valves. In parallel with working on the tricuspid valve, we are looking at and they are working in the lab on moving over to the mitral valve, which is the same valve but on the left side. It’s a higher-stress situation. Its more demanding. There are certain goals we need to achieve in order to in order to do that but we see it as very doable. Also, at the same time, we are looking at transcatheter methodologies for delivering the valve. So, right now it requires an operation, someone open chest surgery. But, we are engineering and the fellows in the lab with CorMatrix are working toward a catheter-based delivery system.
