Abstract
A safety introducer for insertion into a vessel of a patient for infusion of fluids into or withdraw of fluids from the vessel. The introducer includes a catheter assembly having a catheter tube attached to a catheter body. The catheter body has an elongated cavity extending therethrough which is in fluid communication with the catheter tube. The introducer further includes a needle assembly having an elongated needle attached to a flexible tube. The flexible tube is in fluid communication with the elongated cavity. The needle assembly is slidably disposed within the elongated cavity such that a proximally directed force exerted on the flexible tube withdraws the needle assembly substantially completely within the elongated cavity.
