Abstract
A catheter assembly comprising two elements each having a hub disposed at the proximal end thereof. The hubs are constructed so as to be complementary and rotatably engageable as the result of a plurality of threads disposed on the hubs of the two catheter introducer elements. When the threads of the hubs of the two catheter elements are engaged axial disengagement of the hubs is inhibited. The catheter assembly also comprising a means of securing against accidental rotational disengagement. The size and location of the threads and the rotational securement means permits the catheter assembly to have a lower profile because the distance to the hemostasis gasket is reduced thus permitting easier access to the hemostasis gasket.
