Amazing! How does it sense and account for the flex in the stilette as it enters? Was that covered and I missed it?,(reply>), @Brainbook ah that makes sense, I was thinking that the sensor was in the circular base, then is there two sensors in the tip to be able to calculate the orientation or is it simply measuring a single point. Really interesting might have to read up more,(reply>), The tip doesnt really move in the catheter and that's where some of the sensors are.
