Abstract
A two-piece swivel coupling for a catheter system having Luer connections on either end of the coupling. One piece has a recess which receives an O-ring and the other piece has a spigot which projects through the O-ring into a recess. The O-ring provides radial, fluid-tight interference between the spigot and the recess. Means are provided for preventing the pieces from axially compressing the O-ring so that one piece is freely rotatable with respect to the other as the catheter is inserted in a blood vessel through a tortuous path into a patient's heart.
