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.
Claims21
A short catheter tube dividable longitudinally be tearing comprising a tube wall made of modifying polymer intermixed with a base polymer incompatible with the modifying polymer, with both the base polymer and the modifying polymer being inert to human blood and tissue.
A short catheter tube dividable longitudinally by tearing comprising a tube wall made of a base polymer and having at least two longitudinal strips of modifying polymer that extend the length thereof, wherein said base polymer and said modifying polymer are incompatible and inert to human blood and tissue whereby said catheter tube is dividable along said longitudinal strips.
