Access port identification systems and methods
First Claim
1. A power injectable port assembly for use with a power injector system, comprising:
- a power injectable port comprising a housing, a septum, a reservoir, and an outlet stem, the outlet stem having a lumen in fluid communication with the reservoir, wherein the power injectable port;
is rated for use with the power injector system;
is designed to accommodate pressurized injection of contrast media by the power injector system at a desired flow rate; and
includes a radiopaque identifier observable via imaging technology subsequent to subcutaneous implantation of the power injectable port, the radiopaque identifier including an alphanumeric message identifying the power injectable port as suitable for use with the power injector system.

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.

25. A method of using a power injector system, comprising:
-
subcutaneously implanting a power injectable port designed to accommodate pressurized injection of contrast media by the power injector system at a desired flow rate in a computed tomography scanning process, the power injectable port comprising; a housing including a plurality of suture apertures; a septum defining a needle penetrable area bounded by an outer perimeter; a reservoir and an outlet stem having a lumen in fluid communication with the reservoir; and a radiopaque identifier identifying the power injectable port as suitable for power injection, the radiopaque identifier observable via imaging technology through the septum such that a message appears within the outer perimeter; attaching a catheter configured for accessing a vein of a patient to the outlet stem; imaging the power injectable port to observe the radiopaque identifier; and if the radiopaque identifier is observed via the imaging, injecting contrast media through the power injectable port and the catheter.
