You say - They never used ultra sound for exact location.
Actually we have an 'inside running' on the new procedure and device and needle used!
Our nephew invented and patented it - he is actually anesthetist but developed microscopic indentations on very fine needles, that reflect ultrasound so the point of the needle can be positioned within 0.5 mm accuracy.
