Zusammenfassung:A medical device with an implantable portion comprises, in part, an encapsulation sensor In preferred embodiments, the encapsulation sensor comprises at least two electrodes and a circuit configured to sense impedance between the electrodes Cell accumulation and fibrous capsule growth causes an increase in impedance. Functionality of the sensor can be evaluated based at least in part on the sensed impedance
