Abstract
Abstract A female luer connector for intravascular or urological use is provided with a needle having a closed distal end with an opening in the side of the needle. In addition, the needle is sealingly received within a recess of a rubber septum with an interference fit between the distal end of the needle and the septum. A slit may be formed in the septum to facilitate penetration of the needle through the septum when in use. In one embodiment, the septum has an elongated recess so that the needle may be received under compression in one portion for storage purposes and in a second portion when in use.
