The port is configured to be in fluid communication with the cannula. The port also comprises a septum adapted to seal the port against unwanted fluid flow. The introducer cap is adapted to be mounted to the base member and has a needle adapted to extend through the septum and said soft cannula in an assembled position. The infusion cap comprises a lumen adapted to receive an elongate flexible tube. The infusion cap also comprises a hard cannula adapted to be inserted through the septum and to place said soft cannula in fluid communication with said lumen.
