Implantable vascular access port with dual, high-flow trans-chamber and low-flow, access, and needle lock for high-flow

An implantable vascular access port comprising a port body and at least one hollow outlet tube attached to the port body, said port body including:

• a lower or floor wall;
• an upper wall opposed thereto;
• at least one sidewall extending between said upper wall and said lower or floor wall;
• at least one internal chamber defined by said lower or floor wall, said upper wall and said at least one sidewall;
• and
• at least one outlet aperture formed in said at least one sidewall thereof in communication with said at least one internal chamber,
• said upper wall comprising a single unitary septum opposite said bottom wall and at least partially opposite said outlet aperture,
• said upper wall being provided with a first access zone and a second access zone spaced from one another,
• said second access zone defining a perpendicular- or vertical-access path or direction extending through said single unitary septum and substantially perpendicularly to said upper wall and said lower or floor wall,
• said first access zone defining a straight-line-access path or direction extending to said at least one outlet aperture through said single unitary septum and said at least one internal chamber at an angle between 0° and about 70° with respect to the lower or floor wall,
• said single unitary septum being coextensive with at least both said first access zone and said second access zone,
• said single unitary septum being made of self-sealing penetrable material designed for repeated piercing by access needles,
• said at least one hollow outlet tube being in fluid communication with said at least one internal chamber and said at least one outlet aperture.
