A filtering device for removing particles from a fluid of a patient is provided. The filtering device being implantable in the patient's body and comprising a cassette comprising a revolving member, said revolving member having at least two segments each holding a respective filter. The device further comprises a tube forming a fluid passageway through one of the filters in said cassette, wherein the cassette is adapted to, upon revolution of the revolving cylinder, change the filter positioned in the fluid passageway from a first one of said filters to a second one of said filters, thereby allowing particles present on the first filter to be moved away from the fluid passageway, while at the same time changing the filter positioned in the fluid passageway.

Systems and related methods for supplying power to a medical device employ serially-connectable portable batteries. A method of supplying electrical power to a medical device includes discharging a first external battery to output electrical power to a second external battery. Distribution of the electrical power received by the second external battery is controlled to simultaneously charge the second external battery and output electrical power from the second external battery to supply electrical power to the medical device.
