ABSTRACT:
A process for forming the tips on catheters is described in which the catheter is placed on a mandrel and molded in a mold. The mandrel may then be removed and a second mandrel inserted. The second mandrel having a larger diameter and adapted to contact inner surface of the mold to thereby cut any flash formed at the end of the catheter and separate the flash from the catheter tip. Alternatively, the mandrel and catheter are inserted into the mold to mold the outer surface of the catheter thereafter removed and inserted into a die to punch the flash from the tip of the catheter material. The punch process may be carried out by either the same mandrel or a second mandrel adapted to the purpose of cutting or punching the flash from the catheter.
