Abstract
A venous access port assembly having a housing base with a discharge stem, a septum, and a cap. An interior reservoir is defined by a well in the housing base and the bottom surface of the septum, and a passageway extends from the reservoir through the discharge stem. The cap is secured to the housing base and securely retains the septum in the assembly, compressing an annular flange of the septum against a septum seat of the housing base. Horizontal ribs on the interior of the cap snap into complementary grooves on the side wall of the housing base to mechanically lock together the cap and housing base during curing of the solvent bonding agent. The cap is mechanically secured and bonded to the housing base. Crush ribs on the interior surface of the cap, precisely center the cap about the housing base during assembly and compensating for manufacturing tolerances.
