Abstract

The present invention provides a system for attaching a fluid access port to a patient. The system generally comprises an implantable access port with a bottom exit port and method for attaching an access port to a patient. In addition, a tube guard, flexible tube exit port, tissue guard, and porous coupling member are disclosed.

Claims

1. An implantable access port for use with a gastric band for the treatment of obesity, the implantable access port comprising:

a septum surface;

a top housing section comprising a top opening for the septum surface;

a bottom exit tube coupling that provides a partial anchoring of the implantable access port in a pre-selected position;

a bottom housing section, wherein a partial interior vessel is formed by a fluid seal created between a bottom surface of the septum surface and an interior surface of the bottom housing section; and

a porous coupling member having a top surface and a bottom surface, said porous coupling member having a first portion extending substantially parallel to a base of the bottom housing section, wherein the first portion does not comprise a porous surface and a second portion extending substantially parallel to the base of the bottom housing section, wherein the second portion comprises a porous surface, and wherein the first portion is configured to shield a portion of a patient from contact with a needle.

2. The implantable access port of claim 1, wherein the implantable port is configured to shield a coupled tube from inadvertent needle puncture using at least one of an orientation of the bottom exit tube coupling, needle entry orientation, or structures of a body of the implantable port.

3. The implantable access port of claim 1, wherein the porous coupling member is at least one of integral to the implantable access port or coupled to the implantable access port via a coupling agent proximate the top surface of the porous coupling member for mating with the base of the implantable access port.

4. The implantable access port of claim 1, wherein the porous coupling member extends substantially parallel to the base of the bottom housing section, and

wherein the bottom surface of the porous coupling member is configured for anchoring the porous coupling member to a tissue of a patient.

5. The implantable access port of claim 1, wherein the porous coupling member is made from injection moldable plastic or rubber.

6. The implantable access port of claim 1, wherein the porous coupling member is at least one of a partial ring shape or a substantially circular shape.

7. The implantable access port of claim 1, wherein the first portion is proximate to the implantable access port.

8. The implantable access port of claim 1, wherein the bottom housing section further comprises surface features for at least one of positioning a guard plate or channeling fluid from the partial interior vessel to the bottom exit tube coupling.

9. The implantable access port of claim 1, wherein the top housing section and the bottom housing section couple together to place the septum surface under compression.

10. The implantable access port of claim 9, wherein the top housing section and the bottom housing section are securably coupled together via lock tabs.

11. An implantable access port for use with a gastric band for the treatment of obesity, the implantable access port comprising:

a septum surface;

a top housing section comprising a top opening for the septum surface;

a bottom exit tube coupling that provides a partial anchoring of the implantable access port in a pre-selected position;

a bottom housing section, wherein a partial interior vessel is formed by a fluid seal created between a bottom surface of the septum surface and an interior surface of the bottom housing section;

a mesh material oriented between the implantable access port and a coupling member; and

a through hole in the mesh material configured to allow the coupling member to pass through the through hole to mate with a base of the implantable access port.

12. The implantable access port of claim 11, wherein the mesh material is a pre-fabricated mesh material made from injection moldable plastic or rubber.

13. The implantable access port of claim 11, wherein the port is configured to be implanted subcutaneously.

14. A method of securably coupling to a tissue of a patient an implantable access port of an adjustable gastric banding system configured to facilitate fluid transfer to and from the gastric banding system, the method comprising:

subcutaneously coupling an implantable fluid access port having a bottom exit tube coupling to the tissue of the patient, the bottom exit tube coupling made from a silicon rubber material and is configured to provide a partial anchoring of the implantable access port in a pre-selected position, wherein the port comprises a septum configured to receive a needle for fluid transfer; and

coupling a tube of the adjustable gastric banding system to the bottom exit tube coupling.

15. The method of claim 14, further comprising protecting the bottom exit tube coupling via a guard plate internal to the port.

16. The method of claim 14, wherein the subcutaneous coupling is performed via at least one of a mesh material oriented between the implantable access port and a coupling member, sutures, or a porous coupler.

17. An implantable access port for use with a gastric band for the treatment of obesity, the implantable access port comprising:

a septum surface;

a top housing section comprising a top opening for the septum surface;

a bottom exit tube coupling that provides a partial anchoring of the implantable access port in a pre-selected position;

a bottom housing section, wherein a partial interior vessel is formed by a fluid seal created between a bottom surface of the septum surface and an interior surface of the bottom housing section; and

a guard plate configured to shield at least one of the bottom exit tube coupling or a tube from contact with a needle, wherein the guard plate comprises channels configured to allow fluid to pass from the partial interior vessel to the bottom exit tube coupling.

18. The implantable access port of claim 17, wherein the guard plate is internal to the partial interior vessel.

19. An implantable access port for use with a gastric band for the treatment of obesity, the implantable access port comprising:

a septum surface;

a top housing section comprising a top opening for the septum surface;

a bottom exit tube coupling comprising a ball joint socket that provides a partial anchoring of the implantable access port in a pre-selected position; and

a bottom housing section, wherein a partial interior vessel is formed by a fluid seal created between a bottom surface of the septum surface and an interior surface of the bottom housing section.

20. The implantable access port of claim 19, wherein the bottom exit tube coupling further comprises a rubber boot.

21. An implantable access port for use with a gastric band for the treatment of obesity, the implantable access port comprising:
