Abstract

A through the needle catheter is provided where the needle is splittable after removal and the catheter material is formed from an extremely hydrophilic polymer. Upon removal of the needle, the catheter expands with contact to water and other aqueous solutions, such as blood or intravenous dosages. Upon expansion, the outer diameter of the catheter tube seals the tube within the body tissue preventing leakage from the body tissue around the tube.
Also, the inner diameter of the catheter tube expands to allow higher infusion flow rates of intravenous fluids into the body.
