Abstract

An implantable surgical injection port including a housing having a body, a closed distal end, a open proximal end and a fluid reservoir therebetween. The housing includes a needle penetrable septum attached to the housing about the opening. The injection port further includes at least one stabilizing element mounted to the housing for stabilizing the port within tissue. The stabilizing element is a member having an undeployed position and a deployed position. Wherein the element extends radially from the body in the deployed position.

Claims

1. An implantable surgical injection port comprising:

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

b. a needle penetrable septum retained in said open proximal end of said housing; and

c. at least one stabilizing element mounted to said housing for stabilizing said port within tissue, said stabilizing element comprising a member having an undeployed position and a deployed position, wherein said stability element extends radially from said body.

2. The injection port of claim 1, wherein said stability element is flexible.

3. The injection port of claim 1, wherein said stabilizing element is resilient and is attached to said housing so that said stabilizing element is in said deployed position when relaxed and not subjected to a restraining force.

4. The injection port of claim 1, wherein said stabilizing element pivotally attaches to said housing.

5. The injection port of claim 1, wherein said stabilizing element is at least partially made of a metallic wire.

6. The injection port of claim 1, wherein said stabilizing element is at least partially made of a biocompatible polymer.

7. The injection port of claim 1, wherein said stabilizing element comprises a flexible webbing adapted for tissue in-growth, said webbing attached to a flexible support element attached to said housing.

8. The injection port of claim 1, wherein said stabilizing element is removably attachable to said housing.

9. The injection port of claim 1, wherein said stabilizing element includes means for penetrating into tissue as the surgeon presses said injection port into position, and as said injection port changes from said undeployed position to said deployed position.

10. The injection port of claim 1 including at least three stabilizing elements mounted to said housing.

11. An implantable surgical injection port comprising:

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

b. a needle penetrable septum retained in said open proximal end of said housing; and

c. at least one stabilizing element mounted to said housing for stabilizing said port within tissue, said stabilizing element comprising a member having an undeployed position and a deployed position, wherein said stability element extends radially from said body substantially coplanar with said closed distal end of said housing.

12. The injection port of claim 11, wherein said stability element is flexible.

13. The injection port of claim 11, wherein said stabilizing element is resilient and is attached to said housing so that said stabilizing element is in said deployed position when relaxed and not subjected to a restraining force.

14. The injection port of claim 11, wherein said stabilizing element pivotally attaches to said housing.

15. The injection port of claim 11, wherein said stabilizing element is at least partially made of a metallic wire.

16. The injection port of claim 11, wherein said stabilizing element is at least partially made of a biocompatible polymer.

17. The injection port of claim 11, wherein said stabilizing element comprises a flexible webbing adapted for tissue in-growth, said webbing attached to a flexible support element attached to said housing.

18. The injection port of claim 11, wherein said stabilizing element is removably attachable to said housing.

19. An implantable surgical injection port comprising:

a. a housing having a body, 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 stabilizing element mounted to said housing for stabilizing said port within tissue, said stabilizing element comprising a member having an undeployed position and a deployed position, wherein said stability element extends radially from said body substantially coplanar with said closed distal end of said housing; and

d. means for said at least one stability element to penetrate into tissue as the surgeon presses said injection port into position, and as said injection port changes from said undeployed position to said deployed position.

20. The injection port of claim 19 including at least three stabilizing elements mounted to said housing.
