Characterization of balloon-inflatable concentric bipolar microelectrode sensor. (a) The impedance sensor was mounted on a balloon. (b) SEM photo of the finished impedance sensor, highlighting the stretchable sinusoidal cables in response to balloon inflation and the two gluing pads allowed for affixation on the surface of the balloon. (c) The balloon impedance sensor was inserted into the ex-vivo rabbit aorta. (d) Demonstration of balloon inflation prior to impedance assessment. (e) Demonstration of intravascular balloon inflation.
