An implantable access port comprising:
- a housing defining a plurality of chambers, each of said plurality of chambers comprising an opening and an integrated outlet passageway, said plurality of chambers being fluidly interconnected with one another via said integrated outlet passageways;
- an outlet tube defining a single passageway having a first end region and a second end region disposed generally opposite each other, wherein said first end region is fluidly coupled to said integrated outlet passageways and said second end region is configured to deliver fluid from said plurality of chambers to a predetermined location;
- and
- a plurality of septa configured to enclose a respective one of said openings of said plurality of chambers, each of said plurality of septa comprising an exterior, generally concaved surface configured to allow a needle to pass through into a respective one of said chamber, wherein a center region of the septum is the thinnest portion of the septum.
