Abstract
An access port for implantation within the body of a patient for providing repeated access to a specific site within the patient and communicating with the site by an implanted internal catheter. The access ports in accordance with this invention includes a housing having an inlet orifice leading to a reduced diameter guide passageway and a valve capable of external actuation. An external filament such as a needle, guide wire, optical fiber, or external catheter can be introduced into the access device and fed through the housing as the valve is externally actuated. This system allows the introduction of therapeutic agents, the removal of fluids from the body, or the introduction of sensing or articulating devices to the specific site within the patient.
