Abstract

Claims (32)

1. A power injectable venous access port assembly, the assembly comprising:

a housing base having a bottom wall;

a needle penetrable septum sealed against the housing base;

a reservoir formed between the housing base and the septum;

a reservoir lining deposited within the reservoir, wherein the reservoir lining covers at least a portion of the bottom wall, and the reservoir lining comprising a needle impenetrable radiopaque material;

a discharge port extending from the housing, the discharge port comprising a discharge stem forming a fluid passageway between the reservoir and the discharge port; and

an X-ray discernable indicium cut in at least a part of the reservoir lining, wherein the cuts are of a width less than a diameter of a needle used to access the port assembly.

2. The assembly of claim 1 , wherein the reservoir lining is cup-shaped with an open end.

3. The assembly of claim 1 , wherein the radiopaque material is metal.

4. The assembly of claim 1 , wherein the radiopaque material is titanium.

5. The assembly of claim 1 , wherein the X-ray discernable indicium comprises at least one alphabetical letter.

6. The assembly of claim 1 , wherein the X-ray discernable indicium indicates an attribute of the venous access port assembly when X-rays are incident upon the venous access port assembly.

7. The assembly of claim 1 , wherein the reservoir lining contacts an interior surface of a bottom wall of the reservoir.

8. The assembly of claim 1 , wherein the at least one cut is formed as at least one narrow slot having a width only sufficiently wide to be X-ray discernable.

9. The assembly of claim 1 , wherein the X-ray discernable indicium is centered in a bottom wall of the reservoir lining.

10. The assembly of claim 1 , further comprising a cap securing the needle penetrable septum to the housing base.

11. The assembly of claim 2 , wherein the X-ray discernable indicium comprises a plurality of cuts in a side wall of the reservoir lining.

12. The assembly of claim 2 , wherein the X-ray discernable indicium comprises at least one cut in a bottom wall of the reservoir lining.

13. The assembly of claim 2 , wherein the X-ray discernable indicium comprises a plurality of cuts in a side wall and a bottom wall of the reservoir lining.

14. The assembly of claim 2 , wherein the discharge port is welded to the reservoir lining.

15. A venous access port assembly, the assembly comprising:

a housing base having a bottom wall;

a needle penetrable septum sealed against the housing base;

a reservoir formed between the housing base and the septum;

a reservoir lining contained within the reservoir, wherein the reservoir lining covers at least a portion of the bottom wall, and the reservoir lining comprising a needle impenetrable radiopaque material;

a discharge port extending from the housing, the discharge port comprising a discharge stem forming a fluid passageway between the reservoir and the discharge port; and

an X-ray discernable indicium cut in at least a part of the reservoir lining, wherein the cuts are of a width less than a diameter of a needle used to access the port assembly.

16. The assembly of claim 15 , wherein the reservoir lining is cup-shaped.

17. The assembly of claim 15 , wherein the radiopaque material is metal.

18. The assembly of claim 15 , wherein the radiopaque material is titanium.

19. The assembly of claim 15 , wherein the X-ray discernable indicium comprises at least one alphabetical letter.

20. The assembly of claim 15 , wherein the X-ray discernable indicium indicates an attribute of the venous access port assembly when X-rays are incident upon the venous access port assembly.
