  • Publication number: 20190151641
    Abstract: A method of treating a patient using a power-injectable access port, including implanting the power-injectable access port in the patient, imaging the power-injectable access port following implanting, and power injecting a fluid into the patient through the power-injectable access port. The power-injectable access port includes a septum covering a reservoir, the septum including a radiopaque material forming at least one letter, the at least one letter indicating that the power-injectable access port is suitable for power injection. The power-injectable access port is designed to accommodate a pressure developed within the reservoir of at least 35 psi, and a fluid flow rate of at least 1 milliliter per second. Imaging the power-injectable access port produces an image, and the method includes identifying the at least one letter on the image to confirm that the power-injectable access port is suitable for power injecting a fluid.

    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.
