Abstract

A power-injectable access port includes a housing defining an internal cavity and including a plurality of suture apertures, a needle-penetrable septum captured by the housing enabling needle access to the internal cavity, a stem having a lumen in fluid communication with the internal cavity, the stem configured for coupling to a catheter, and a radiopaque identification feature observable via imaging technology subsequent to subcutaneous implantation of the port, the feature indicating that the port is suitable for power injection.

Claims

1. A power-injectable access port, comprising:

a housing defining an internal cavity and including a plurality of suture apertures;

a needle-penetrable septum captured by the housing enabling needle access to the internal cavity;

a stem having a lumen in fluid communication with the internal cavity, the stem configured for coupling to a catheter; and

a radiopaque identification feature observable via imaging technology subsequent to subcutaneous implantation of the port, the feature indicating that the port is suitable for power injection.

2. The power-injectable access port according to claim 1, wherein the radiopaque identification feature is an alphanumeric message positioned on an exterior of the housing.

3. The power-injectable access port according to claim 2, wherein the exterior of the housing is an outwardly facing bottom surface thereof.

4. The power-injectable access port according to claim 1, wherein the imaging technology includes x-ray imaging technology.

5. The power-injectable access port according to claim 1, wherein the radiopaque identification feature is an alphanumeric message including an abbreviation for computed tomography.

6. The power-injectable access port according to claim 5, wherein the abbreviation for computed tomography includes the letters “

C” and

“

T”

.

7. The power-injectable access port according to claim 1, wherein the housing includes a metallic portion and the radiopaque identification feature is disposed on the metallic portion.

8. The power-injectable access port according to claim 1, wherein the housing further comprises a cap and a base.

9. The power-injectable access port according to claim 8, wherein the radiopaque identification feature includes the letters “

CT”

.

10. A power-injectable access port, comprising:

a housing defining an internal cavity and including a plurality of suture apertures;

a needle-penetrable septum captured by the housing enabling needle access to the internal cavity;

a stem having a lumen in fluid communication with the internal cavity, the stem configured for coupling to a catheter; and

a radiopaque identifier including the letters “

CT”

observable via x-ray imaging technology subsequent to subcutaneous implantation of the port to indicate that the port is suitable for power injection.
