With Chimaera, what we've done is we've combined smart sensing technology, pre-operative planning, we've taken small implant form-factors; and we've combined both implant delivery with surgical tool to provide a completely connected, unified surgical system that has the potential to take a surgery that maybe only four or five people in the world can carry out today and make it accessible to a broad cross-section of general surgeons. By doing that we make it accessible to a much, much broader patient population.
