  • Dividable catheter
    Patent number: 4402685
    Abstract: A dividable short catheter tube made of a modifying polymer intermixed with, or inserted into, a base polymer. The modifying polymer is usually one which is incompatible with the base polymer.The dividable short catheter tube is readily tearable longitudinally so that it can be removed from around a flexible catheter after the flexible catheter has been guided into a patient by means of the short catheter previously positioned in a body puncture.The tube can be extruded from a mixture of the two polymers or it can be extruded with modifying polymer longitudinal strips in walls of the base polymer.
