Systems and methods for identifying an access port
First Claim
1. An access port for providing subcutaneous access to a patient, comprising:
- a port base defining a fluid cavity, the port base formed from a base material;
a substrate separate from the port base formed from a substrate material, the substrate attached to the port base, the substrate including an inner surface facing toward the fluid cavity and an outer surface facing away from the fluid cavity; and
a radiopaque material adhered to the substrate inner surface prior to attachment of the substrate to the port base, the radiopaque material including an identification feature.

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 engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.

14. A power injectable access port, comprising:
-
a port base defining a fluid cavity, the port base formed from a base material; a substrate separate from the port base formed from a substrate material, the substrate material being the same as the base material a radiopaque material deposited on a surface of the substrate, the radiopaque material including a feature identifying the access port as power injectable, wherein the substrate is coupled to the port base such that; the radiopaque material is encapsulated between the substrate material and the base material; and the feature identifying the access port as power injectable is visible through the substrate prior to implantation. - View Dependent Claims (15, 16, 17, 18, 19)
