Abstract

A method of power injecting a contrast medium into a patient, including obtaining a power-injectable access port suitable for power injection. The power injectable access port includes a housing defining a reservoir, and a septum. The septum may include a self-sealing material, and a radiopaque material. The radiopaque material may form a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The power-injectable access port may be structured for accommodating a pressure developed within the reservoir of at least 35 psi, and may be designed to accommodate a fluid flow rate of at least 1 milliliter per second. After implanting the power-injectable access port in the patient, the method may include imaging the power-injectable access port and confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium.

Claims

1. A method of power injecting a contrast medium into a patient, comprising:

obtaining a power-injectable access port suitable for power injection, the power injectable access port comprising;

a housing defining a reservoir; and

a septum, comprising;

a self-sealing material; and

a radiopaque material forming a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection, wherein;

the power-injectable access port is structured for accommodating a pressure developed within the reservoir of at least 35 psi, and

the power-injectable access port is designed to accommodate a fluid flow rate of at least 1 milliliter per second;

implanting the power-injectable access port in the patient;

imaging the power-injectable access port following the implanting;

confirming via the selected pattern in the septum that the power-injectable access port is suitable for injecting the contrast medium; and

injecting the contrast medium through the power-injectable access port into the patient.

2. The method of power injecting according to claim 1, wherein the selected pattern in the septum includes one or more letters, and wherein the confirming step comprises recognizing the one or more letters as indicating that the power-injectable access port is suitable for injecting the contrast medium.

3. The method of power injecting according to claim 1, wherein the injecting step comprises using an infusion set including a non-coring needle in fluid communication with a tubing, and a connector affixed to an outer surface of the tubing.

4. The method of power injecting according to claim 3, wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 100 psi.

5. The method of power injecting according to claim 3, wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 400 psi.

6. The method of power injecting according to claim 3, wherein each of the non-coring needle, the tubing, and the connector have a burst pressure of at least 600 psi.

7. The method of power injecting according to claim 3, wherein the injecting step comprises injecting the contrast medium through the infusion set at a rate of at least 5 milliliters per second.

8. The method of power injecting according to claim 1, wherein the imaging step comprises taking an x-ray of the power-injectable access port following the implanting step.

9. The method of power injecting according to claim 1, further comprising, prior to the injecting step, verifying that the power-injectable access port is suitable for injecting the contrast medium by visually perceiving information outside of the patient on an element packaged with the power-injectable access port.

10. The method of power injecting according to claim 9, wherein the element is selected from the group consisting of a key chain, a bracelet, a wrist band, a sticker, a patient ID card, a label, and combinations thereof.

11. The method of power injecting according to claim 1, wherein the injecting step comprises injecting the contrast medium through the power-injectable access port at a rate of between 1 milliliter per second and 5 milliliters per second.

12. The method of power injecting according to claim 1, further comprising attaching a proximal end of a venous catheter to the power-injectable access port and guiding a distal end of the venous catheter through a vasculature of the patient to a target destination for the contrast medium.
