ABSTRACT:
An implantable vascular access device includes a housing having an inlet, an outlet, an interior chamber defined therein and a valve positioned between the inlet and the interior chamber. The valve is subcutaneously manipulated between an open position, in which fluid can flow between the inlet and the interior chamber, and a closed position in which the valve occludes the inlet. The device may include any combination of multiple inlets, outlets and/or interior chambers. In the preferred embodiment, the housing includes two separate interior chambers suitable for the inflow and outflow of a typical hemodialysis procedure. A method for accessing a vascular structure is provided which includes the steps of subcutaneously implanting the device connecting one end of a cannula to the outlet of the device and another end of the cannula to a selected vascular structure. The valve of the device is manipulated to permit fluid communication between the inlet of the device and the selected vascular structure. A needle is introduced through the inlet opening to access the selected vascular structure.
