ABSTRACT:
One aspect of the present invention is an implantable patient access port which provides a percutaneous route for access using an external filament such as an external catheter, needle, wire or optical fiber. The access port incorporates an internal reservoir for the retention of an antibacterial fluid and further includes a means for refilling the fluid chamber. Refilling is accomplished through providing a separate fluid reservoir within the housing and further through the provision of a barrier which can be penetrated using a needle. Another aspect of the invention is the provision of a blood check device which prevents migration of red blood cells from a percutaneously placed accessed catheter outside of the patient. The device includes a filter media element and connector for permitting in-line placement of the blood check in the access catheter.
