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 housing comprising:
a housing base at least partially defining at least one reservoir; and
a peripheral portion comprised at least partially of a radiopaque material, the peripheral portion including X-ray discernable indicia configured to indicate, under X-ray examination, that the venous access port assembly is rated for power injection, the X-ray discernable indicia being one or more voids defined in at least a portion of the radiopaque material, and
a needle penetrable septum.
2. The venous access port assembly of claim 1 , further comprising a skirt overmolded about at least a portion of the housing.
3. The venous access port assembly of claim 2 , wherein the skirt is overmolded about the peripheral portion.
4. The venous access port assembly of claim 2 , wherein the skirt comprises radiotransparent or radiolucent material.
5. The venous access port assembly of claim 1 , wherein the X-ray discernable indicia extend through a height of the radiopaque material from a top surface of the radiopaque material to a bottom surface of the radiopaque material.
6. The venous access port assembly of claim 1 , wherein the X-ray discernable indicia extend through a height of the radiopaque material of the peripheral portion from a top surface of the radiopaque material to a bottom surface of the radiopaque material.
7. The venous access port assembly of claim 1 , wherein the housing further comprises a cap.
