Venous access port with molded and/or radiopaque indicia
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.

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.
