  "country": "US",
  "title": "How Medical Ports Show Power Injection Rating on X-rays",
  "original_title": "Venous access port with molded and/or radiopaque indicia",
  "summary": "This patent describes a medical port that has special X-ray visible markings to clearly show if it's safe for high-pressure injections, helping doctors avoid mistakes after the port is inside a patient.",
  "what_it_does": "This patent describes a venous access port assembly that includes a base, a peripheral surface, and a septum. The key feature is the peripheral surface, which has X-ray discernable indicia, or markings, that identify the port as safe for power injection. These markings are integrally molded into the surface. For example, the peripheral surface itself might be made of an X-ray visible material, and the markings could be either more of that material or tiny voids (empty spaces) within it. Alternatively, the surface could be mostly transparent to X-rays, with the markings created by applying an X-ray blocking substance, or by making voids in that applied substance. This allows medical staff to confirm the port's capabilities even after it has been surgically placed inside a patient.",
  "what_it_does_not_cover": [
    "Does not cover venous access ports that lack X-ray discernable indicia to identify power injection rating.",
    "Does not cover indicia that are not integrally molded into the peripheral surface of the port.",
    "Does not cover X-ray visible markings on medical devices other than venous access port assemblies.",
    "Does not cover indicia that are visible only to the naked eye and not designed for X-ray imaging.",
    "Does not cover ports where the X-ray discernable indicia do not relate to power injection rating."

  "abstract": "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.",
