ABSTRACT:
A method of making a curved-tip (coude) catheter which comprises: inserting an end of a flexible, thermoplastic tube into the bore of a closed-end, hollow, tubular die which defines the desired curve of the curved-tip catheter. The tubular die is heated to a temperature above the plastic melt temperature of the thermoplastic tube, while advancing the tube into the die, to cause at least about 0.5 cm. of the tube end to collapse into a generally solid, curved mass. The die and tube contained therein are then cooled to a temperature below the plastic melt temperature, and the tube is withdrawn having a closed, formed coude tip.
