Thanks Peter and David you have both have valid points
but Peter the particular document you refer to relates to therapeutic goods often such things get bogged down in bearacracy to the detrement of those concerned just so people cover thy asses so too speak
If an individual is prepared to sign a waiver and understands that it may not be that magic bullet then so be it
In this case the procedure involves no drug trials
the test for the blood vessel blockage is quite common I think it's referred to as a Doppler
likewise the procedure to clear blood vessels of blockage is quite common
so I cannot see why there should be prolonged delays in setting up clinical trails on a group of test subjects
sorry it may seem cynical but it just doesn't make sense.
