a body portion comprising an upper body part, a lower body part attachable to the upper body part, and a self-sealing septum
between the upper body part and the lower body part,
wherein the upper body part and the lower body part are formed of implantable, biocompatible material, and
wherein a reservoir is defined by the body portion;
an outlet configured to be in flow communication with the reservoir;
an access site located on the body portion; and
an entry site located on the body portion, the entry site being disposed opposite the outlet and being configured to permit
insertion of one of a guidewire and a stylet through the body portion and into the outlet,
wherein an outer surface of the septum forms a portion of an exterior surface of the device,
wherein the device is configured to permit access, from an exterior of the device, to the reservoir via the access site without
passing through the entry site and without passing through the outlet,
wherein the outlet is configured to be connected to a catheter,
wherein the device is configured so that when the outlet is connected to the catheter, the reservoir is in continuous, unimpeded
fluid communication with the catheter,
wherein an entry through the entry site is achieved via the self-sealing septum, and
wherein an access through the access site is achieved without penetrating the self-sealing septum.
