Abstract
A port is adapted to be implanted to a body with its top exposed to the environment. The port has a housing defining a chamber that has an opening at the top of the housing. An aperture having a lumen attached thereto is formed at the lower portion of the chamber. For infusion, an insert that has an internal passageway that connects a fluid inlet at its top surface and a bore at its sidewall is sealingly mated to the chamber. The bore sealingly aligns with the aperture. After infusion, the insert is removed, and a blank insert is fitted to the chamber. A band of tissue ingrowth media encircles the housing to form an aseptic barrier where the outer wall of the housing and the tissue of the body encircling the housing meet.
Core Innovation
The invention is an implantable port comprising a housing with an opening and at least one aperture, and a mating insert whose top surface remains accessible from the environment after implantation. The insert can provide a fluid path through a passageway aligned with the housing aperture and a lumen, or can seal the housing when not used for infusion. Variants include multiple fluid paths, replaceable lumens or catheters, and rotatable or locking insert arrangements.
The port may include tissue-ingrowth media around the housing wall, which forms an aseptic barrier between the wall and surrounding body tissue. The claimed arrangements retain a visually viewable or environmentally accessible insert surface after implantation and may provide one or more fluid paths to a selected body location.
Claims Coverage
The patent includes three independent claims, covering an implantable port with an accessible insert, a visually viewable insert and lumen, and a visually accessible port with tissue-ingrowth media forming an aseptic barrier.
Mating insert in an implantable port
A housing has an interior, an opening and at least one aperture through its wall. A mating insert fits into the housing, with its top surface substantially planar with the housing top and accessible from the environment after implantation.
Visually viewable insert and lumen
A housing has an opening and at least one lumen extending from an aperture in its wall. A mating insert fits within the housing, which is implanted to a depth that leaves the insert's top surface visually viewable.
Accessible port with an aseptic barrier
A housing with at least one lumen and a mating insert is arranged so that the insert's top surface remains accessible from the environment after implantation. Tissue-ingrowth media encircles the housing wall and forms an aseptic barrier between the wall and surrounding body tissue.
The independent claims cover three implantable-port arrangements centered on a mating insert that remains accessible or visually viewable after implantation. They further specify a housing aperture and lumen, and, in one claim, tissue-ingrowth media that forms an aseptic barrier.
Stated Advantages
Avoids repeated skin punctures by enabling frequent needleless access.
Facilitates access to the port and replacement of components.
Reduces infection risk through a tissue-ingrowth interface that forms an aseptic barrier.
Documented Applications
An implantable port for needleless access and infusion, routing fluid through a passageway and lumen to a selected body location.
