VENOUS ACCESS PORT ASSEMBY WITH X-RAY DISCERNABLE INDICIA
First Claim
1. A venous access port assembly for implantation into a patient, comprising:
- a housing having a discharge port, the housing having a housing base defining a bottom wall of at least one reservoir, with the housing base having an outwardly facing bottom surface, andthe housing base including a reservoir lining of radiopaque material defining X-ray discernable indicia that indicate an attribute of the assembly when an X-ray of the patient is taken so that the practitioner can be advised of the attribute of the assembly after implantation,the reservoir lining further comprising an aperture to establish a fluid communication with a passageway of the discharge port.

Abstract
A venous access port assembly (10) having a housing base (22) with a discharge stem (16), a septum (14), a cap (20) and an interior reservoir (26). The port assembly (10) is provided with X-ray discernable indicia (60,62) to identify an attribute of the assembly (10) 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 (60,62) through a reservoir lining (50) 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 (52) or bottom wall (54).

13. A venous access port assembly for implantation into a patient, comprising:
-
a housing, comprising a housing base defining a bottom wall of at least one reservoir; a discharge port extending from the housing, the discharge port comprising a discharge stem forming a fluid passageway between the at least one reservoir and the discharge port; at least one reservoir lining configured to be insertable within the at least one reservoir, the at least one reservoir comprising radiopaque material defining X-ray discernable indicia that indicate an attribute of the venous access port assembly when X-rays are incident upon the venous access port assembly, the reservoir lining further comprising an aperture to establish a fluid communication between the at least one reservoir and the discharge stem. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A venous access port system for implantation into a patient, comprising:
-
a housing, comprising a housing base defining a bottom wall of at least one reservoir; a catheter; a discharge port extending from the housing to facilitate fluid communication between the catheter and the at least one reservoir, the discharge port comprising a discharge stem forming a fluid passageway between the at least one reservoir and the discharge port; at least one reservoir lining configured to be insertable within the at least one reservoir, the at least one reservoir comprising radiopaque material defining X-ray discernable indicia that indicate an attribute of the venous access port when X-rays are incident upon the venous access port, the reservoir lining further comprising an aperture to establish a fluid communication with a passageway between the at least one reservoir and the catheter.
