A system is provided for preventing the accumulation of cumulative matter from clogging a stent, such as a plastic tubular drainage stent for use in the biliary system. The system includes a stent having one or more magnetically reactive objects moveably disposed therein and an actuation device, such as a glove, having one or more magnets thereon. When the actuation device is waived near the one or more magnetically reactive objects of the stent, it actuates them by manually manipulating the one or more magnetically reactive objects of the stent by attracting or repelling them such that they contact the stent walls dislodging cumulative matter attached thereto. As a result of the system, the stent is able to remain resident within the patient for an extended period of time before becoming clogged and needing to be replaced. |
