Assemblies for identifying a power injectable access port
First Claim
1. A power-injectable access port, comprising:
- a housing structured for accommodating forces attendant to power injection such that the power-injectable access port is suitable for power injection;
a septum including a radiopaque material forming a selected pattern when an x-ray is taken through the septum, the selected pattern indicating that the housing of the power-injectable access port is suitable for accommodating forces attendant to power injection;
a reservoir; and
an outlet stem in fluid communication with the reservoir.

Abstract
A power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second. The access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is structured for accommodating a pressure developed within the reservoir of at least 35 psi. The septum may include a radiopaque material forming a selected pattern when an x-ray is taken through the septum. The pattern may identify the access port as capable of accommodating injection of contrast media at a rate of at least 1 milliliter per second and/or as capable of accommodating a pressure developed within the reservoir of at least 35 psi. The pattern may identify the location of the septum following implantation of the power-injectable access port.

17. A power-injectable access port, comprising:
-
a septum designed to be repeatedly punctured with a suitable access mechanism, the septum including at least one identification attribute comprising a radiographic marker designed to indicate that a housing of the power-injectable access port is suitable for accommodating a particular fluid flow rate and forces attendant to power injection; and the housing defining an aperture for capturing the septum, the housing and septum defining a reservoir, the housing structured for accommodating flow rates attendant to power injection such that the power-injectable access port is suitable for accommodating the particular fluid flow rate; and an outlet stem in fluid communication with the reservoir. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
