A stent is provided that is able to resist clogging from cumulative matter found within a fluid that passes therethrough. The stent includes a mass moveably disposed therein, wherein movement of the stent tends to dislodge any cumulative matter accumulated within the stent. As a result, the device is able to remain resident within the patient for an extended period of time before becoming clogged and needing to be replaced.
