Abstract

An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue. The port includes a housing having a closed distal end, a open proximal end and a fluid reservoir therebetween. The port further includes a needle penetrable septum attached to the housing about the opening. The port even further includes at least one attachment mechanism mounted to the housing at a pivot point along an outer periphery of the housing. The attachment mechanism is an arcuate hook pivotable with respect to the housing, wherein the arcuate hook having a length extending substantially greater than 90° about the pivot point.

Claims

1. An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue, said port comprising:

a. a housing having a closed distal end, a open proximal end and a fluid reservoir therebetween;

b. a needle penetrable septum attached to said housing about said opening; and

c. at least one attachment mechanism mounted to said housing at a pivot point along an outer periphery of said housing, said attachment mechanism comprising an arcuate hook pivotable with respect to said housing, said arcuate hook having a length extending substantially greater than 90°

about said pivot point.

2. The injection port of claim 1 wherein said housing includes at least one recessed portion at said distal end thereof for receiving a free end of said attachment mechanism when said port is in its deployed position.

3. The injection port of claim 1 wherein said arcuate hook has a length extending at least 180°

4. The injection port of claim 1 wherein said attachment mechanism includes a sharp free end.

5. The injection port of claim 1 further including a catheter connection tube attached to said housing and in fluid communication with said reservoir.

6. The injection port of claim 1 wherein said housing comprises titanium.

7. The injection port of claim 1 wherein said septum self seals after being punctured by a needle and the needle is withdrawn.

8. The injection port of claim 1 wherein said septum comprises silicone.

9. The injection port of claim 1 wherein said injection port includes at least three said attachment mechanism.

10. The injection port of claim 9 wherein said attachment mechanisms are equally spaced along said outer periphery.

11. The injection port of claim 1 wherein said outer periphery of said injection port is adjacent said distal end of said housing.

12. An implantable surgical injection port having an undeployed position, and a deployed position wherein it is attached to tissue, said port comprising:

a. a housing having a closed distal end, a open proximal end and a fluid reservoir therebetween;

b. a needle penetrable septum attached to said housing about said opening; and

c. at least one attachment mechanism mounted to said housing at a pivot point along an outer periphery of said housing, said attachment mechanism comprising an arcuate hook pivotable with respect to said housing, said hook having a fixed end attached to said housing and a free end, said arcuate hook having a length extending substantially at least 180°

about said pivot point.

d. said housing further including at least one recessed portion at said distal end thereof for receiving said free end of said attachment mechanism when said port is in its deployed position.

13. The injection port of claim 12 wherein said free end is sharp.

14. The injection port of claim 12 further including a catheter connection tube attached to said housing and in fluid communication with said reservoir.

15. The injection port of claim 12 wherein said housing comprises titanium.

16. The injection port of claim 12 wherein said septum self seals after being punctured by a needle and the needle is withdrawn.

17. The injection port of claim 12 wherein said septum comprises silicone.

18. The injection port of claim 12 wherein said injection port includes at least three said attachment mechanism.

19. The injection port of claim 12 wherein said attachment mechanisms are equally spaced along said outer periphery.

20. The injection port of claim 12 wherein said outer periphery of said injection port is adjacent said distal end of said housing.
