Abstract
The present invention relates to a drug delivery device which is implantable within a mammal and adapted for long-term efficient drug delivery to surrounding tissue. The drug delivery device is part of a drug delivery system that includes a catheter and a drug feed system. The drug delivery device includes a support structure that defines a drug reservoir and a capillary interface which facilitates vascular ingrowth while inhibiting blockage of drug delivery openings in the reservoir.
