Abstract

A power-injectable access port suitable for providing subcutaneous access to a patient and suitable for power injection. The access port includes a septum, a housing, and a reservoir defined by the septum and the housing. The septum may include a material that seals passages formed by puncturing the septum with a hollow slender element or another suitable access mechanism, 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. The housing and the septum may be structured for accommodating a pressure developed within the reservoir of at least 35 psi. The power-injectable access port may be designed to accommodate a flow rate of at least 1 milliliter per second of a fluid.

Claims

1. A power-injectable access port for providing subcutaneous access to a patient and suitable for power injection, comprising:

a septum, comprising;

a material that seals passages formed by puncturing the septum with a hollow slender element or another suitable access mechanism, and

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

a housing defining an aperture for capturing the septum, the housing and the septum defining a reservoir, wherein;

the housing and the septum are 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 flow rate of at least 1 milliliter per second of a fluid.

2. The power-injectable access port according to claim 1, wherein the pattern includes an alphanumeric character.

3. The power-injectable access port according to claim 1, wherein the septum includes a tenon region, and wherein the housing defines a complimentary mortise region structured for accepting at least a portion of the tenon region.

4. The power-injectable access port according to claim 1, wherein the septum further comprises at least one structural element for limiting deformation of the septum in response to a pressure developed within the reservoir.

5. The power-injectable access port according to claim 4, wherein the at least one structural element comprises one or more extension legs of the septum.

6. The power-injectable access port according to claim 4, wherein the at least one structural element extends from a lower surface of the septum.

7. The power-injectable access port according to claim 6, wherein the at least one structural element includes at least one barb positioned at least partially within the septum.

8. The power-injectable access port according to claim 4, wherein the at least one structural element extends laterally through at least a portion of the septum.

9. The power-injectable access port according to claim 4, wherein the at least one structural element abuts or is proximate to at least a portion of an upper surface of the septum.

10. The power-injectable access port according to claim 4, wherein the at least one structural element forms a pattern selected from the group consisting of a generally triangular pattern, a generally rectangular pattern, and a plurality of substantially parallel lines.

11. The power-injectable access port according to claim 10, wherein the at least one structural element is at least partially embedded within the septum and forms a closed plane figure.

12. The power-injectable access port according to claim 1, further comprising at least one feature configured for identifying a maximum flow rate through the power-injectable access port.

13. The power-injectable access port according to claim 1, wherein the septum comprises a structural frame and a pliant material.

14. The power-injectable access port according to claim 13, wherein the frame comprises a material with a shore A hardness of 80 or more, and the pliant material comprises a shore A harness of 50 or less.

15. The power-injectable access port according to claim 13, wherein the frame comprises a plurality of apertures.

16. The power-injectable access port according to claim 1, wherein the access port is suitable for injecting contrast media therethrough at a rate of between 1 milliliter per second and about 5 milliliters per second.

17. The power-injectable access port according to claim 1, wherein the access port is structured for accommodating a pressure of up to about 180 psi developed within the reservoir.
