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 for initially attaching the port to tissue wherein the attachment mechanism is made from a bioabsorbable material.

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 for initially attaching said port to tissue, said attachment mechanism comprising a bioabsorbable material.

2. The injection port of claim 1 wherein said attachment mechanism comprises 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.

3. The injection port of claim 1 wherein said attachment mechanism comprises 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 greater than 90°

about said pivot point.

4. The injection port of claim 1 wherein said attachment mechanism comprises polyglactin.

5. The injection port of claim 1 wherein said attachment mechanism comprises poliglecaprone.

6. The injection port of claim 1 wherein said attachment mechanism comprises iron.

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

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

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 The injection port of claim 1 wherein said septum self seals after being punctured by a needle and the needle is withdrawn.

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

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 The injection port of claim 1 wherein said septum self seals after being punctured by a needle and the needle is withdrawn.

11. 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;

c. at least one attachment mechanism mounted to said housing for initially attaching said port to tissue, said attachment mechanism comprising a bioabsorbable material; and

d. an adjustable gastric band attached to said housing via a catheter connection tube attached to said housing and in fluid communication with said reservoir.

12. The injection port of claim 11 wherein said attachment mechanism comprises 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.

13. The injection port of claim 11 wherein said attachment mechanism comprises 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 greater than 90°

about said pivot point.

14. The injection port of claim 11 wherein said attachment mechanism comprises polyglactin.

15. The injection port of claim 11 wherein said attachment mechanism comprises poliglecaprone.

16. The injection port of claim 11 wherein said attachment mechanism comprises polydioxanone.

17. The injection port of claim 11 wherein said attachment mechanism comprises iron.

18. The injection port of claim 11 wherein said housing comprises titanium.
