ABSTRACT:
An implantable access device which permits the introduction of an external filament such as a catheter, guide wire or optical fiber into a patient for communication with an internal catheter located within the body of the patient. The device includes a housing having inlet and outlet openings and a passageway communicating between the openings. The first sealing mechanism provides resistance to fluid flow through the passageway when the external filament is not present within the device. This first sealing mechanism allows the transfer of fluids through the passageway when the filament is present within the passageway. A second sealing mechanism engages and seals about the exterior perimeter of the external filament when the filament is located within the device.
