The invention relates to a device ( 5 ) for delivery of substances ( 9 ) to and removal of bodily substances ( 22 ) from a tissue ( 2 ) or vessel ( 25 ) of a body using an element ( 6 ) to be positioned in the tissue ( 2 ) or vessel ( 25 ). To provide a device of this type for the delivery and removal of substances ( 9, 22 ), which has a small and robust construction and may be used as easily and comfortably as possible by the patient, the element ( 6 ) is at least partially made of porous material and comprises at least one inlet ( 7 ) for supplying the substance ( 9 ) to be delivered and at least one outlet ( 10 ) for draining the bodily substances ( 22 ), the inlet ( 7 ) being connectable via an inlet line ( 13 ) to a container for the substances ( 9 ) to be delivered, so that in the event of a pressure gradient between inlet ( 7 ) and outlet ( 10 ), the substance ( 9 ) to be delivered, during the traversal of the porous element ( 6 ), is delivered via the mantle surface of the porous element ( 6 ) to the tissue ( 2 ) or vessel ( 25 ) and the bodily substances ( 22 ) are extracted from the tissue ( 2 ) or vessel ( 25 ) via the mantle surface of the porous element ( 6 ) and drained via a drain line ( 12 ) connectable to the outlet ( 10 ).
