Systems and methods for radiographically identifying an access port
First Claim
1. An access port for providing subcutaneous access to a patient, comprising:
- a body defining a fluid cavity accessible via a septum, the body including a first material; and
a radiopaque insert attached to the body of the access port, the insert including;
an injection molded mixture including the first material and a metal oxide, wherein the insert includes an identification feature that is observable via x-ray imaging technology subsequent to subcutaneous implantation of the access port in the patient, the identification feature 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 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. In one embodiment, an identification feature is included on a molded insert that is incorporated into the access port so as to be visible after implantation via x-ray imaging technology.
