ABSTRACT OF THE DISCLOSURE A catheter introducer assembly, having a blood seal is disclosed. The assembly is made up of a needle having proximal and distal ends. The needle is provided with an area of enlarged diameter which keeps a needle shield or seal assembly from sliding off the needle. A hub is attached to the needle at the proximal end of the needle. A catheter assembly made up of cannula and a catheter adapter attached to the cannula is mounted axially on the needle. The cannula is mountable concentrically around the needle such that the catheter assembly is slidable on the needle and the needle can be withdrawn from the catheter assembly. The introducer assembly is provided with a seal assembly mountable on the needle adjacent the catheter adapter such that the seal assembly is slidable on the needle. The seal assembly carries a seal adapted to limit blood flow from the catheter adapter.
