Venous access port with molded and/or radiopaque indicia
First Claim
1. A venous access port assembly for implantation into a patient, comprising:
- a housing comprising a base defining a bottom wall of at least one reservoir, a discharge port extending from the at least one reservoir, and a flange adjacent to the at least one reservoir, the flange comprising a height extending from a top surface of the flange to a bottom surface of the flange, the flange further comprising X-ray discernable indicia configured to indicate, under X-ray examination, that the port assembly is rated for power injection, the X-ray discernable indicia located in the flange and extending through the height of the flange from the top surface of the flange to the bottom surface of the flange so that the X-ray discernable indicia are visually discernable to a naked eye from both the top surface of the flange and the bottom surface of the flange prior to implantation of the port assembly; and
a needle-penetrable septum communicating with the housing.

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.

12. An implantable venous access port assembly comprising:
-
a needle-penetrable septum; a housing securing the needle-penetrable septum, the housing comprising a housing base defining at least one reservoir, and a flange extending radially from the housing base, the flange comprising; X-ray discernable material; a height extending from a top surface of the flange to a bottom surface of the flange; and one or more cutouts extending entirely through the height of the flange from the top surface of the flange to the bottom surface of the flange, the one or more cutouts comprising one or more voids in the X-ray discernable material, the one or more cutouts configured to indicate, under X-ray examination, that the port assembly is rated for power injection, the one or more cutouts further configured to be visually discernable to a naked eye from both the top surface of the flange and the bottom surface of the flange prior to implantation of the port assembly; and a discharge port extending from the housing. - View Dependent Claims (13, 14, 15, 16)
