ABSTRACT:
A transcutaneous infusion system comprises an implantable infusate injection port for conducting infusate from the port to an infusion site in the body. The port is supplied with infusate through a penetrable septum located directly under the skin. To infuse the patient, a flexible injection cannula encircling a needle which is slightly longer than the cannula is inserted through the septum into the port and then the needle is withdrawn leaving the free end of the flexible cannula in the port. The opposite end of the cannula is provided with a fitting for connecting the cannula to the outlet of a fluid administration set. The system also includes a bracket removably connected to the cannula and taped to the patient adjacent the injection site so that the bracket anchors the cannula and its associated fittings and tubing against the patient's skin, while assuring that the cannula is not bent to an extent that will stop fluid flow into the port.
