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, a bottom wall of the internal cavity, and an outwardly facing bottom surface, the bottom wall comprising a metal, the housing 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, the radiopaque identification feature positioned on the outwardly facing bottom surface etched into the metal;

wherein subsequent to subcutaneous implantation of the power-injectable access port, the radiopaque identification feature conveys to an observer using the imaging technology that the power-injectable access port is suitable for power injection.

2. The power-injectable access port according to claim 1, wherein the radiopaque identification feature comprises an alphanumeric message.

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

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

5. The power-injectable access port according to claim 4, wherein the abbreviation for computed tomography includes letters “

C” and

“

T”

.

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

7. The power-injectable access port according to claim 6, wherein the radiopaque identification feature includes letters “

CT”

.

8. The power-injectable access port according to claim 1, wherein the radiopaque identification feature is selected from the group consisting of one or more symbols, one or more patterns, one or more characters, one or more designs, and combinations thereof.

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

C” and

“

T”

.

10. A power-injectable access port, comprising:

a housing defining an internal cavity, a bottom wall of the internal cavity, and an outwardly facing bottom surface, the bottom wall comprising a metal, the housing 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 letters “

CT”

observable via x-ray imaging technology subsequent to subcutaneous implantation of the power-injectable access port to indicate that the power-injectable access port is suitable for power injection, the letters “

CT”

positioned on the outwardly facing bottom surface etched into the metal.
