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.
