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.
