Inplantable access devices
First Claim
1. An implantable access port for permitting the introduction of an external filament such as an external catheter, needle, guide wire or optical fiber within a patient comprising:
- a housing defining first and second generally funnel shaped entrance orifices,mounting means for supporting said housing subcutaneously,first and second housing passageways extending respectively from said first and second entrance orifices and respectively defining first and second exit orifices,andfirst and second articulating valve means respectively disposed in said first and second passageways, each of said first and second valve means for permitting said external filament to pass through said valve means while restricting the flow of fluids across said valve means.

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.

7. An implantable access port for permitting the introduction of an external filament such as an external catheter, needle, guide wire or optical fiber within a patient comprising:
-
a first housing defining a first generally funnel shaped entrance orifice; a first housing passageway extending from said first entrance orifice and defining a first exit orifice; a first articulating valve means disposed in said first passageway, said first valve means for permitting an external filament to pass through said first valve means while restricting the flow of fluid across said first valve means; a second housing defining a second generally funnel shaped entrance orifice, a second housing passageway extending from said second entrance orifice and defining a second exit orifice; a second articulating valve means disposed in said second passageway, said second valve means for permitting an external filament to pass through said second valve means while restricting the flow of fluid across said second valve means; and mounting means for supporting both said first and second housings subcutaneously. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
