Abstract

Smart stent systems and methods of using the same to evaluate fluid flow through a stent are provided. Systems according to various aspects of the invention include a stent having a coil configured as a resonant circuit and a reader. During use, an oscillation is produced in the coil of the stent by applying an RF field to the stent. Then, a parameter associated with the oscillation is obtained to evaluate fluid flow through the stent. The systems and methods may be used in a variety of applications, such as detecting the occurrence of re-stenosis.
