Remote Monitoring of Absorbable Cardiovascular Stents using Millimetre Waves

In this paper, we propose a corrosion monitoring scheme for the absorbable cardiovascular stents composed of magnesium alloys. We show that the structural integrity of such mesh-type tubular stents can be evaluated using millimetre-scale electromagnetic waves. With the passage of time, the strut thickness of the stent decreases due to corrosion which is subsequently observed in terms of a frequency shift in the simulated scattering response.
