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.
Claims20
A port comprising:
- a housing having an interior defined by a bottom, a non-ending wall and a top that has an opening that opens to the interior of the housing;
- at least one aperture at a selected location through the non-ending wall;
- an insert having a body structure with a top surface, a cross dimension and a depth that enables it to matingly fit to the interior of the housing via the opening of the housing, the top surface of the insert in substantial planar relationship with the top of the housing after insertion to the housing;
- wherein the housing of the port is adapted to be implanted into a body with the top surface of the insert accessible from environment.
A port adapted to be implanted into a body while leaving a portion thereof viewable visually, comprising:
- a housing having an interior defined by a bottom, a non-ending wall having an outer surface and a top that has an opening that opens to the interior of the housing;
- at least one lumen extending from at least one aperture at the non-ending wall away from the housing;
- an insert having a body structure with a top surface, a cross dimension and a depth that enables it to matingly fit to the interior of the housing via the opening of the housing;
- wherein the housing of the port is adapted to be implantable into the body to a depth where the top surface of the insert is viewable visually.
A port viewable visually and accessible from environment after implantation, comprising:
- a housing having an interior defined by a bottom, a non-ending wall having an outer surface and a top that has an opening that opens to the interior of the housing;
- at least one lumen extending from at least one aperture at the non-ending wall;
- tissue ingrowth media encircling the outer surface of the non-ending wall;
- an insert having a body structure with a top surface, a cross dimension and a depth that enable the insert to be matingly fitted into the interior of the housing via the opening of the housing;
- wherein the housing of the port is implantable into a body to a depth where the top surface of the insert remains accessible from the environment;
- and
- wherein once implanted to the body, the tissue ingrowth media forms an aseptic barrier between the non-ending wall and tissue of the body encircling the wall.
