The present invention relates to a drug delivery device (12) which is implantable within a mammal, and adapted for long-term efficient drug delivery to surrounding tissue (13). The drug delivery device (12) is part of a drug delivery system (10) that includes a catheter (14) and a drug feed system (18). The drug delivery device (12) includes a support structure (22) that defines a drug reservoir (23), and a capillary interface (28) which facilitates vascular ingrowth while inhibiting blockage of drug delivery openings (22A) in the reservoir (23). |
