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.

Claims

1. A venous access port assembly for implantation into a patient, comprising:

a housing having a base defining a bottom wall of at least one reservoir, the housing further having a discharge port extending from the at least one reservoir, and a peripheral surface adjacent to the at least one reservoir, the peripheral surface including indicia molded therein indicating a characteristic of the assembly; and

a needle-penetrable septum communicating with the housing.

2. The assembly of claim 1, wherein the molded indicia further includes radiopaque markings, whereby the indicia is visible by X-ray examination when the assembly is subcutaneously implanted in a patent.

3. The assembly of claim 2, wherein the radiopaque markings comprise radiopaque marking fluid.

4. The assembly of claim 3, wherein the fluid contains tungsten.

5. The assembly of claim 1, wherein the peripheral surface is comprised of a metal material, whereby the indicia is visible by X-ray examination when the assembly is subcutaneously implanted in a patent.

6. The assembly of claim 1, wherein the peripheral surface extends outwardly from the base about a perimeter of the at least one reservoir.

7. The assembly of claim 1, wherein the peripheral surface further includes suture openings, and the indicia is located within predetermined suture openings.

8. The assembly of claim 1, wherein the indicia is formed of peripheral surface material.

9. The assembly of claim 1, wherein the indicia is formed by voids in the peripheral surface.

10. The assembly of claim 1, wherein the assembly is at least partially comprised of radiotransparent material.
