Professor Cathal O'Donnell:

I passed one in my way in this morning. It is of that nature. The device we have is robust and we are very confident in it. We absolutely had some teething troubles, but I went through this process eight years ago with the previous install of the LIFEPAK defibrillators and we had exactly the same experience then. I am sure that, in eight years’ time if we go through a procurement process and switch to another manufacturer’s device, we will probably go through the same experience again. We go through a very complex process.
