Abstract

An access port for implantation within the body of a patient. The device includes an implanted internal catheter for providing repeated access to at least one predetermined site within the patient. The access port according to this invention includes a housing having an inlet orifice leading to an exit orifice and an implanted catheter, which includes at least two subpassageways. A first valve mechanism is positioned in the device to normally prevent the flow of fluids through the implanted catheter. A second valve mechanism is positioned in at least one of the subpassageways of the internal catheter. An external filament such as a needle, guide wire, optical fiber, or external catheter can be introduced into the access device and fed therethrough. This system thus allows the introduction of therapeutic agents, the removal of fluids from the body, or the introduction of sensing or articulating devices to the specific sites within the patient.
