I agree with the majority of the above sentiments. Another important perspective to obtain would be that of the surgeon. Within my company, the R&D engineers work directly with the surgeons on designs and get their direct feedback on whether something like this would be feasible. They aid in developing some inputs to a design from their shear experience. Surgeons, even nurses, offer a great wealth of insight in terms of not only how the end user/patient would use this device but also functionally whether it is a design that would not impede the original flow of an operating room. Ergonomics, size, weight are all considerations to take into account with not only the patient but the surgeons and nurses who will be implanting this device per say.
