“Catheter-based Electrochemical Sensing for Safer Minimally-Invasive Procedures"

Doctors treat cancers and other diseases by blocking blood flow through tiny catheters, but today they must rely on repeated X-ray imaging to guess when treatment is complete. This project investigates an alternative approach: embedding electrical impedance sensors directly onto microcatheters to measure flow-related changes from within the vessel. Over the summer, Ronny will help design and test compact sensing electronics and electrode geometries suitable for microcatheters, and work to translate impedance signals into physiologically meaningful information under realistic flow conditions. This approach could reduce reliance on radiation-based imaging while providing more consistent, quantitative feedback during procedures.
