ABSTRACT:
A catheter fabrication method and apparatus. Two rotating contact rollers define a nip to engage a mandrel used in fabricating an elongated tubular catheter. The rollers pull the mandrel from the catheter as a retaining block prevents the catheter from moving with the mandrel. The rollers rotate in opposite directions and are driven by a variable speed direct current motor.
