Abstract
An access portal is provided including a housing, a body defining a fluid reservoir, and a septum enclosing the fluid reservoir. A stem in fluid communication with the fluid reservoir extends from the fluid reservoir. The access portal also includes a reservoir insert disposed within the fluid reservoir, in which the reservoir insert decreases the fluid fill volume of the reservoir.
