Access port identification systems and methods
An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.
1. An access port for providing subcutaneous access to a patient, comprising:
a body defining a fluid cavity accessible by inserting a needle through a septum; and
at least one radiopaque identification feature of the access port observable via imaging technology subsequent to subcutaneous implantation of the access port, the at least one radiopaque identification feature including one or more alphanumeric characters identifying the access port as a power-injectable port.
2. The access port according to claim 1 , wherein the imaging technology includes x-ray imaging technology.
3. The access port according to claim 1 , wherein the radiopaque identification feature is defined on a bottom surface of the access port.
4. The access port according to claim 1 , wherein the radiopaque identification feature is defined as a recessed feature in the body of the access port.
5. The access port according to claim 1 , wherein the access port includes a metallic portion and the radiopaque identification feature is disposed on the metallic portion.
6. The access port according to claim 1 , wherein the at least radiopaque identification feature includes at least one of the following: a symbol, a pattern, a mark, or any combination thereof.
7. The access port according to claim 1 , wherein the at least one radiopaque identification feature includes at least one cavity extending inward from a bottom surface of the body.
8. The access port according to claim 1 , wherein the at least one radiopaque identification feature indicates an orientation of the access port when the access port is imaged by x-ray imaging technology.
9. The access port according to claim 1 , wherein the one or more alphanumeric characters includes the letters “C” and “T.”
10. An access port for providing subcutaneous access to a patient, comprising:
a metallic body defining a fluid cavity; and
an radiopaque identification feature included on a bottom surface of the access port, the feature being an alphanumeric message observable via imaging technology subsequent to subcutaneous implantation of the access port, the alphanumeric message identifying the access port as a power-injectable port.
11. The access port according to claim 10 , wherein the alphanumeric message is recessed in the bottom surface of the access port.
12. The access port according to claim 10 , wherein the alphanumeric message is disposed below the port fluid cavity.
13. The access port according to claim 10 , wherein the alphanumeric message is proximate a periphery of the bottom surface of the access port.
14. The access port according to claim 10 , wherein the body includes titanium and includes a base, the base defining at least a portion of the bottom surface of the access port.
15. The access port according to claim 10 , wherein the alphanumeric message is disposed on an inside bottom surface of the fluid cavity.
16. An access port for providing subcutaneous access to a patient, comprising:
a body including a metallic material and defining a fluid cavity, the fluid cavity covered by a septum; and
at least one recessed identification feature defined by the body, observable via x-ray imaging technology subsequent to subcutaneous implantation of the access port, the at least one identification feature identifying the access port as a power-injectable access port.
17. The access port according to claim 16 , wherein the at least one recessed identification feature is included on an inside surface of the fluid cavity.
18. The access port according to claim 16 , wherein the at least one recessed identification feature includes an engraved feature and is relatively more x-ray transmissive with respect to other portions of the access port body.
19. The access port according to claim 16 , wherein the at least one recessed identification feature includes one or more alphanumeric characters.
20. The access port according to claim 19 , wherein the one or more alphanumeric characters includes the letters “C” and “T.”
