Venous access port with molded and/or radiopaque indicia
A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface 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 peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface 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 peripheral surface applied with the radiopaque agent.
1. A venous access port assembly for implantation into a patient, comprising:
a needle-penetrable septum;
a housing comprising a housing base at least partially defining at least one reservoir; and
a peripheral component external to the housing, the peripheral component comprised at least partially of a radiopaque material, wherein:
the peripheral component includes one or more X-ray discernable voids extending through a height of the peripheral component,
the one or more X-ray discernable voids indicating under X-ray examination that the venous access port assembly is capable of withstanding pressures used during injection of contrast fluid.
2. The venous access port assembly of claim 1 , wherein the peripheral component is integral with and extends outwardly from the housing.
3. The venous access port assembly of claim 1 , wherein the peripheral component extends substantially about a perimeter of the housing.
4. The venous access port assembly of claim 1 , further comprising a radiotransparent or radiolucent skirt overmolded about at least a portion of the housing.
5. The venous access port assembly of claim 1 , further comprising a radiotransparent or radiolucent skirt overmolded about the peripheral component.
6. The venous access port assembly of claim 1 , wherein the one or more X-ray discernable voids extend completely through the peripheral component.
7. The venous access port assembly of claim 1 , wherein the housing further comprises a cap.
8. The venous access port assembly of claim 1 , wherein the one or more X-ray discernable voids are shaped as letters or symbols capable of indicating an orientation of the venous access port assembly after implantation.
9. A venous access port assembly for implantation into a patient, comprising:
a needle-penetrable septum;
a housing comprising a housing base at least partially defining at least one reservoir; and
a peripheral component external to the housing, the peripheral component comprised at least partially of a radiopaque material, wherein:
the peripheral component includes one or more X-ray discernable voids extending through a height of the peripheral component,
the one or more X-ray discernable voids are visible under X-ray examination, and
the one or more X-ray discernable voids are in the shape of letters “CT”.
10. The venous access port assembly of claim 9 , wherein the peripheral component is integral with and extends outwardly from the housing.
11. The venous access port assembly of claim 9 , wherein the peripheral component extends substantially about a perimeter of the housing.
12. The venous access port assembly of claim 9 , further comprising radiotransparent or radiolucent skirt overmolded about at least a portion of the housing.
13. The venous access port assembly of claim 9 , further comprising a radiotransparent or radiolucent skirt overmolded about the peripheral component.
14. The venous access port assembly of claim 9 , wherein the one or more X-ray discernable voids extend completely through the peripheral component.
15. The venous access port assembly of claim 9 , wherein the one or more X-ray discernable voids indicate, under X-ray examination, that the venous access port assembly is capable of withstanding pressures used during injection of contrast fluid.
16. The venous access port assembly of claim 9 , wherein the housing further comprises a cap.
17. The venous access port assembly of claim 9 , wherein the one or more X-ray discernable voids indicate an orientation of the venous access port assembly after implantation.
