Assemblies for identifying a power injectable access port
First Claim
1. A method of power injecting a fluid through an access port, comprising:
- providing a power-injectable access port suitable for injecting contrast media therethrough at a rate of at least 1 milliliter per second, the power-injectable access port including;
a housing;
a septum;
a reservoir; and
an outlet stem in fluid communication with the reservoir, the power-injectable access port structured for accommodating a pressure developed within the reservoir of at least 35 psi;
attaching a catheter to the outlet stem;
implanting the power-injectable access port and the catheter into a patient;
inserting a distal end of a needle through the septum and into the reservoir; and
injecting contrast media through the needle at a rate of at least one milliliter per second.

Abstract
An assembly for identifying a power injectable vascular access port, including a vascular access port and an identification feature. The port is structured for power injection and includes a housing and a septum together defining a reservoir. A radiographic feature incorporated into the port is perceivable via x-ray following subcutaneous implantation, the radiographic feature identifying the port as suitable for flowing fluid at a fluid flow rate of at least 1 mL/sec therethrough. A structural feature of the port is perceivable via palpation following subcutaneous implantation, the structural feature identifying the port as suitable for accommodating a pressure within the reservoir of at least 35 psi. The identification feature is separated from the port and confirms that the port is both suitable for flowing fluid at a rate of at least 1 mL/sec therethrough and suitable for accommodating a pressure within the reservoir of at least 35 psi.
