Systems and methods for radiographically identifying an access port
First Claim
1. A power injectable access port, comprising:
- a port base including a first fluid cavity;
a first radiopaque identification feature comprising a silk screen deposit having a thickness protruding from an outer surface of the port base such that it is perceivable by sight and touch prior to implantation of the power injectable access port, the first radiopaque identification feature observable via imaging technology subsequent to subcutaneous implantation of the power injectable access port, the first radiopaque identification feature indicating that the power injectable access port is suitable for power injection;
a port cap; and
a first septum captured between the port cap and the port base.

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 an insert that is incorporated into the access port so as to be visible after implantation via x-ray imaging technology.
