ABSTRACT:
An access port (10) for implantation adapted for providing repeated access to specific tissue within a patient and communicating with the tissue by an internal implanted catheter (52). The access ports according to this invention incorporate an enlarged entrance orifice (13) with a funnel shaped internal cavity that narrows down to a reduced diameter passageway (18). An articulating catheter valve (24) is provided within the passageway which normally prevents the flow of fluids through the valve but which can be penetrated by an external introduced filament (32) such as a catheter. After implantation, an external filament (32) is introduced into the port (10) and guided by the passageway into registry with the catheter valve (24). Continued feeding of the filament (32) causes the filament to pass through the valve (24). Thereafter, with a catheter (32) inserted, therapeutic agents can be infused into the patient, or body fluids can be withdrawn. Alternate embodiments disclose various valve concepts (56) and means for providing a change in direction of an introduced filament inserted through the access device. Additional embodiments disclose the concepts of providing an antimicrobial fluid bath (98) within the device for prevention of infection and various approaches for securely connecting an internal catheter (52) to an access port.
