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 dual housing having two inlet orifices each leading to a reduced diameter guide passageway. An external filament such as a needle, guide wire, optical fiber, or external catheter can be introduced into either of the inlet orifices and fed through the housing. This system allows for the introduction of therapeutic agents, the removal of fluids, or the introduction of sensing or articulating devices to multiple sites within the patient.
