The present invention is an implantable medical device that is used deliver materials or energy into a patient's physiology, or from one region of a patient's physiology to another. The device includes a port element with a passageway therethrough for directing and anchoring a conduit element in a desired location. The implantable port stabilizes an elongated conduit within human physiology for long-term use, and includes a support passageway formed through the port and extending between an upper surface and a lower surface of the port, wherein the support passageway is sized and shaped for receiving the elongated conduit slideably inserted therethrough. The device includes a tissue ingrowth scaffold fixedly disposed on at least a portion of at least one surface of the implantable port for positioning in contact with adjacent tissue.
