Abstract

A system for attaching an access port to bodily tissue includes an access port assembly and including an access port having a generally central axis. The access port assembly further includes an attachment mechanism structured to enable the access port to be attached, for example, to an abdominal muscle of a patient. The delivery tool includes a handle having a generally longitudinal axis and a delivery head structured to engage the access port assembly, and an activation mechanism for enabling deployment of the attachment mechanism when the delivery head is so engaged with the access port assembly. The delivery tool is configured such that the longitudinal axis of the handle is spaced apart from the generally central axis of the access port when the delivery head is so engaged with the access port assembly.

Claims

1. A system for attaching an access port to bodily tissue, the system comprising:

an access port assembly including

an access port having a generally central axis and including a bottom, a sidewall and a needle penetratable septum,

an attachment mechanism structured to enable the access port to be attached to bodily tissue,

a delivery tool including

a handle having a generally longitudinal axis,

a delivery head structured to engage the access port assembly, and

an activation mechanism for enabling deployment of the attachment mechanism when the delivery head is so engaged with the access port assembly;

the delivery tool being configured such that the longitudinal axis of the handle is spaced apart from the generally central axis of the access port when the delivery head is so engaged with the access port assembly.

2. The system according to claim 1 wherein the access port bottom is integral with the access port sidewall.

3. The system of claim 2 wherein the access port sidewall and access port bottom are a unitary configuration.

4. The system of claim 3 wherein the access port sidewall and access port bottom are titanium.

5. The system of claim 2 wherein the access port assembly further includes a housing including a housing sidewall surrounding the access port sidewall and an actuator assembly rotatable with respect to the housing sidewall.

6. The system of claim 1 wherein the activation mechanism of the tool comprises a cable mechanism.

7. The system of claim 6 wherein the cable mechanism includes a cable comprising a tungsten material.

8. The system of claim 6 wherein the cable mechanism comprises a cable extending along the handle to the delivery head.

9. The system of claim 6 wherein longitudinal displacement of the cable mechanism causes rotational movement of the attachment mechanism when the delivery head is engaged to the access port assembly.

10. The system of claim 8 wherein the cable includes a substantially straight proximal portion and a curved distal portion.

11. The system of claim 1 wherein the attachment mechanism comprises at least one wire anchor.

12. The system of claim 11 wherein the wire anchor comprises a bent wire having a multi-faceted tip.

13. The system of claim 1 wherein the attachment mechanism comprises at least one anchor having a curved distal portion and a pivotal proximal portion substantially perpendicular with the curved distal portion.

14. The system of claim 1 wherein the attachment mechanism comprises at least one anchor having a spiral distal portion and a straight proximal portion substantially perpendicular with the spiral distal portion.

15. A delivery tool for attaching an access port assembly to bodily tissue, the access port assembly including deployable fasteners and an access port and a generally central axis, the tool comprising:

a handle having a generally longitudinal axis;

a delivery head at a distal end of the handle and structured to engage an access port assembly having deployable fasteners, and

an activation mechanism for enabling deployment of the fasteners when the delivery head is so engaged with the access port assembly;

the delivery tool being configured such that the longitudinal axis of the handle is spaced apart from the generally central axis of the access port when the delivery tool is so engaged with the access port assembly.

16. The tool of claim 15 wherein the activation mechanism of the tool comprises a cable mechanism.

17. The tool of claim 16 wherein the cable mechanism includes a cable comprising a tungsten material.

18. The tool of claim 16 wherein the cable mechanism comprises a cable extending along the handle to the delivery head.

19. The tool of claim 16 wherein longitudinal displacement of the cable mechanism causes rotational movement of the attachment mechanism when the delivery head is engaged to the access port assembly.

20. The tool of claim 18 wherein the cable includes a substantially straight proximal portion and a curved distal portion.
