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 The catheter tube (2) is then withdrawn from the exit point until the wing (3) is pulled into the incision.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.

Claims2

Dependent claims

The method of intravenous alimentation that comprises the steps of:

(a) making a first incision in the patient;
(b) inserting one end of a catheter tube having a small transverse wing made of a biologically acceptable material that is substantially non-adherent to growing tissue fixedly attached to said tube at a location along its length, through the first incision and routing the tubing under the skin through an exit point removed from the first incision;
(c) withdrawing the tubing from the exit point until the transverse wing is under the skin at the edge of the first incision and surgically closing the first incision over the transverse wing;
(d) cutting the portion of the tubing exiting from the exit point to a length appropriate so that, when it is reinserted through the exit point and under the skin, it is of an appropriate length for introduction into a suitable vein;
(e) re-introducing the withdrawn tubing under the skin into a suitable vein;
and
(f) introducing a suitable infusate into the patient through said catheter.
