ABSTRACT:
Catheters (1) are constructed from a catheter tube (2) to which is firmly attached a transverse cross bar or wing (3). The improved catheter is particularly well suited for hyperalimentation of infants. In use, an incision is made in the patient, usually behind the right ear, and the tail of the catheter is routed through the incision under the skin to a remote exit point which is usually on the neck. The catheter tube (2) is then withdrawn from the exit point until the wing (3) is pulled into the incision. The incision is then closed so as to firmly lock the wing and catheter in place. The tail of the catheter is then cut to the desired length and the tail is introduced into an appropriate vein (e.g. the external jugular vein). The opposite or inlet end of the catheter tube is then connected to a suitable source of infusate and alimentation is begun.
