Abstract
A vascular access port includes a base with a floor. A cap is engaged with the base to form a reservoir above the floor as a septum seals the reservoir in a fluid-tight manner. An outlet is in fluid communication with the reservoir. At least one of the base and cap is formed by metal injection molding. The cap and base may be engaged with a snap fit connection or a rotatable connection. The fluid communication may be along a non-tangential non-radial flow path. The flow path may be asymmetrical and may also include textured walls.
