Access port identification systems and methods
DC CAFC
First Claim
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.

Abstract
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.
