Abstract:
A catheter for the continuous infusion of a liquid medication from a drug delivery device into a patient comprising:a micro-bore tubing having a uniform internal diameter of from about 0.001â€³ to about 0.010â€³, the micro-bore tubing having a first and a second end and a length from about 24 inches to about 48 inches, a needle attached to an outside surface of the micro-bore tubing at the first end of the micro-bore tubing, the needle being insertable through a puncturable wall of the drug delivery device, the micro-bore tubing being severable at a selected point between the first end and the second end in order to change the flow rate of the liquid medication passing there through to a predetermined greater flow rate, the internal diameter and the length of the micro-bore tubing, in combination, being chosen such that the micro-bore tubing, once severed provides the predetermined flow rate through the catheter when the drug delivery device is operated at a predetermined delivery pressure.
