Beschreibung
Zusammenfassung:	A probe for monitoring stents comprising: a first coupling port to launch an electromagnetic field onto a stent, such that a guided electromagnetic wave may be propagated through at least a portion of the stent; and a second coupling port to collect the electromagnetic field from the guided electromagnetic wave of the stent. Also provided is a system comprising the probe, and a method for monitoring stents comprising: sensing an input signal related to an electromagnetic field launched by the first coupling port onto the stent, and sensing an output signal related to the electromagnetic field collected by the second coupling port; obtaining a transmission coefficient between the first coupling port and the second coupling port; performing a frequency response of the transmission coefficient; and comparing the frequency response of the transmission coefficient with a reference frequency response.
