What is it about?

In this work, we report a non-drifting pressure sensor for FFR pressure sensing catheter, based on capacitive technology, and reduced number of wires by introducing sensor readout (ASIC) to the tip of the catheter.

Why is it important?

Fractional flow reserve (FFR) index offers a cost-effective and convenient method for measuring the optimal stent deployment for patients with stenosis in a coronary artery. Clinicians are asking for FFR index catheters that are more accurate, smaller, cheaper and easier to use.


This new ultrathin capacitive MEMS pressure sensor die with corresponding readout ASIC circuit offers better accuracy, robustness and automated assembly for FFR catheters.
