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 therethrough 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.
1. An access port for providing subcutaneous access to a patient, comprising:
a metallic body defining a cavity accessible by inserting a needle through a septum, the metallic body including:
a first side surface from which an outlet stem extends;
a second side surface different from the first side surface, the second side surface having a concave portion; and
a bottom surface bounded by a bottom perimeter including a concave portion contiguous with the second side surface concave portion, the bottom surface further including at least one alphanumeric message observable via imaging technology subsequent to implantation of the access port, the alphanumeric message identifying the access port as being power injectable.
2. The access port according to claim 1 , wherein the metallic body includes a third side surface different from the first side surface and second side surface, the third side surface having a concave portion contiguous with a second concave portion in the bottom perimeter.
3. The access port according to claim 1 , wherein the first side surface is connected to the second side surface by a first radius.
4. The access port according to claim 1 , wherein the first side surface is connected to the second side surface by a first radius, the second side surface is connected to the third side surface by a second radius, and the third side surface is connected to the first side surface by a third radius.
5. The access port according to claim 1 , wherein the imaging technology is x-ray imaging technology.
6. The access port according to claim 1 , wherein the at least one alphanumeric message is etched in the bottom surface and, with respect to other portions of the metallic body, is relatively more x-ray transmissive.
7. The access port according to claim 1 , wherein the alphanumeric message includes the letters “C” and “T.”
8. The access port according to claim 1 , wherein the alphanumeric message is “CT.”
