Abstract

A venous access port assembly having a housing base, a flange, and a septum. The housing base defines an interior reservoir. The flange 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 flange from a top surface to a bottom surface of the flange. According to one aspect, the flange may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material of the flange, or they may be formed by voids in the X-ray discernable material. According to another aspect, the flange 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 flange applied with the radiopaque agent.

Claims

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

a housing comprising;

a base defining at least one reservoir; and

a flange adjacent to the at least one reservoir, the flange comprising an X-ray discernable material, a top surface, a bottom surface, and one or more voids extending through the X-ray discernable material of the flange from the top surface of the flange to the bottom surface of the flange, wherein the one or more voids are X-ray discernable indicia configured to indicate, under X-ray examination, that the assembly is rated for power injection; and

a needle-penetrable septum communicating with the housing.

2. The assembly of claim 1, wherein at least a portion of the X-ray discernable material is disposed within the one or more voids.

3. The assembly of claim 1, wherein the flange extends outwardly from the at least one reservoir.

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

5. The assembly of claim 1, wherein the housing further comprises a skirt overmolded about at least a portion of the base.

6. The assembly of claim 5, wherein the skirt is further overmolded about the flange.

7. The assembly of claim 5, wherein the skirt comprises a radiotransparent or radiolucent material.

8. The assembly of claim 1, wherein the X-ray discernable indicia further indicate, under X-ray examination, that the assembly is adapted to withstand high pressures used for injection of contrast fluid.

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

a housing comprising;

a housing base defining at least one reservoir; and

a flange adjacent to the at least one reservoir, the flange comprising an X-ray discernable material, a top surface, a bottom surface, and one or more voids extending through the X-ray discernable material of the flange from the top surface of the flange to the bottom surface of the flange, wherein the one or more voids are X-ray discernable indicia configured to indicate, under X-ray examination, that the assembly is rated for power injection; and

a needle-penetrable septum secured to the housing.

10. The venous access port assembly of claim 9, wherein at least a portion of the X-ray discernable indicia are material is disposed within the one or more voids.

11. The venous access port assembly of claim 9, wherein the flange extends outwardly from the at least one reservoir.

12. The venous access port assembly of claim 9, wherein the flange extends outwardly from the housing base about a perimeter of the at least one reservoir.

13. The venous access port assembly of claim 9, wherein the housing further comprises a radiotransparent or radiolucent skirt overmolded about at least a portion of the housing base.

14. The venous access port assembly of claim 13, wherein the radiotransparent or radiolucent skirt is further overmolded about the flange.

15. The venous access port assembly of claim 9, wherein the X-ray discernable indicia further indicate, under X-ray examination, that the assembly is adapted to withstand high pressures used for injection of contrast fluid.

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

a housing comprising;

a housing base comprising a well comprising a bottom floor and side walls, the bottom floor and side walls defining at least one reservoir; and

a flange adjacent to the at least one reservoir, the flange comprising an X-ray discernable material, a top surface, a bottom surface, and one or more voids extending through the X-ray discernable material of the flange from the top surface of the flange to the bottom surface of the flange, wherein the one or more voids are X-ray discernable indicia configured to indicate, under X-ray examination, that the assembly is rated for power injection;

a needle-penetrable septum; and

a cap securing the needle-penetrable septum to the housing.

17. The venous access port assembly of claim 16, wherein at least a portion of the X-ray discernable material is disposed within the one or more voids.

18. The venous access port assembly of claim 16, wherein the flange extends outwardly from the well.

19. The venous access port assembly of claim 16, wherein the flange extends outwardly from the housing base about a perimeter of the at least one reservoir.

20. The venous access port assembly of claim 16, wherein the housing further comprises a radiotransparent or radiolucent skirt overmolded about at least a portion of the housing base.

21. The venous access port assembly of claim 20, wherein the radiotransparent or radiolucent skirt is further overmolded about the flange.

22. The venous access port assembly of claim 16, wherein the X-ray discernable indicia further indicate, under X-ray examination, that the assembly is adapted to withstand high pressures used for injection of contrast fluid.
