Abstract
An implantable device for the dosed administration of medicaments to the human body includes a first chamber for storing a medicament and having a refill opening sealed by a pierceable septum and an outlet opening communicating with an outlet catheter, a second chamber separated from the first chamber by a flexible diaphragm which serves to apply pressure to the medicament, and a hollow fiber capillary filter disposed at the outlet opening of the first chamber to act as a filter.
