  • Patent number: 9610432
    Abstract: A venous access port assembly having a housing base with a discharge stem, a septum, a cap, and an interior reservoir. The port assembly is provided with X-ray discernable indicia to identify an attribute of the assembly after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. The indicia are cutouts through a reservoir lining of radiopaque material such as metal where the cutouts have narrow slot width are in the form of one or more sets of alphabetical letters such as “CT” in the lining's side wall or bottom wall.

  • Publication number: 20170056638
    Abstract: A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the peripheral surface applied with the radiopaque agent.

The housing base is provided with X-ray discernable indicia to identify an attribute of the assembly after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. Such indicia can be depicted as cutouts through a disc of radiopaque material where the cutouts are in the form of alphabetical letters such as “CT”, or can be a set of discrete elements of radiopaque material, that are affixed along the bottom surface of the housing base or embedded within the thickness of the bottom housing wall.

  • Patent number: 9052025
    Abstract: A bidirectional side-slit duckbill valve apparatus for use with catheters and similar devices. The apparatus can comprise a duckbill valve configured to allow fluid to flow through it only in a first direction and one or more side-slit valves configured to allow fluid to only flow through them in a second direction, opposite the first direction. In an embodiment, fluid can only flow through the duckbill valve if it is under a substantially positive pressure and can only flow through the side-slit valves if it is under a substantially negative pressure. In an embodiment, fluid that is not pressurized will not flow through either the duckbill valve or the side-slit valve. In an embodiment, the bidirectional side-slit duckbill valve apparatus can also comprise a funnel for directing a guidewire.

  • Patent number: 8257325
    Abstract: A venous access port assembly having a housing base with a discharge port, a septum and a cap. An interior reservoir is defined by a well in the housing base and a bottom of the septum, and a passageway extends from the reservoir through the discharge port. The housing base includes a base flange having integrally molded therein indicia identifying an attribute of the assembly. The indicia could be formed of base flange material, or could be formed by voids in the base flange material. If of plastic material, the molded indicia could be applied with a radiopaque agent, thereby allowing the indicia (“CT”) to appear on an X-ray of the patient in a manner informing a practitioner of a particular attribute of the assembly.
