Abstract
A specific configuration for an over the needle catheter having a tapered outer wall and an angled introducer tip is disclosed. The catheter is molded of polyurethane material which is treated with a surface lubricant to ease the over the needle introduction of the catheter after venipuncture. The polyurethane material permits a minimal wall thickness for maximum flow with requisite strength and flexibility characteristics.
