Abstract

Various methods and devices are provided for reorienting an implantable port. In one embodiment, an implantable port is provided and includes a base adapted to be anchored to tissue, and a housing pivotally mounted on the base and having a septum formed therein and adapted to receive fluid and to provide access to a fluid reservoir formed within the housing. In an exemplary embodiment, the housing can be pivotally mounted to the base using a ball and socket joint. For example, at least one of a distal surface of the housing and a proximal surface of the base is convex, and the other one of the distal surface of the housing and the proximal surface of the base is concave.

Claims

1. An implantable port, comprising:

a base adapted to be anchored to tissue; and

a housing pivotally mounted on the base and having a septum formed therein and adapted to receive fluid and to provide access to a fluid reservoir formed within the housing.

2. The implantable port of claim 1, wherein the housing is pivotally mounted to the base using a ball and socket joint.

3. The implantable port of claim 1, wherein at least one of a distal surface of the housing and a proximal surface of the base is convex, and the other one of the distal surface of the housing and the proximal surface of the base is concave.

4. The implantable port of claim 1, wherein the base includes one or more suture-receiving members adapted to receive a suture for anchoring the base to tissue.

5. The implantable port of claim 1, wherein the base includes one or more anchors adapted to be deployed into tissue.

6. The implantable port of claim 1, wherein the housing includes a magnetic portion adapted to align the housing with an external magnet.

7. The implantable port of claim 6, wherein the magnetic portion is disposed around an opening in the housing having the septum.

8. A gastric restriction system, comprising:

an implantable gastric restriction device configured to form a restriction in a patient; and

an implantable port in fluid communication with the implantable gastric restriction device and configured to receive fluid from a fluid source external to the patient, the port including a base adapted to anchor to tissue and a housing that is pivotally coupled to the base.

9. The gastric restriction system of claim 8, wherein the housing is pivotally coupled to the base using a ball and socket joint.

10. The gastric restriction system of claim 8, wherein at least one of a distal surface of the housing and a proximal surface of the base is convex, and the other one of the distal surface of the housing and the proximal surface of the base is concave.

11. The gastric restriction system of claim 8, wherein the housing includes a septum formed therein and adapted to receive fluid and to provide access to a fluid reservoir formed within the housing.

12. The gastric restriction system of claim 8, wherein the housing includes a magnetic portion.

13. The gastric restriction system of claim 11, further comprising a catheter extending between the gastric restriction device and the implantable port for delivering fluid from the fluid reservoir of the housing to the gastric restriction device to adjust an amount of restriction applied by the gastric restriction device.

14. A method of accessing a port implanted in tissue, comprising:

pivoting a housing disposed beneath a skin surface and movably coupled to a base anchored in tissue to position a septum formed on the housing in a desired position.

15. The method of claim 14, further comprising inserting a needle into the septum formed in the housing, and injecting fluid into the housing.

16. The method of claim 14, wherein the base of the port is anchored to fascia.

17. The method of claim 15, wherein the fluid is delivered from the housing to a gastric restriction device coupled to the housing.

18. The method of claim 14, further comprising aligning the housing by attracting a magnetic portion on the housing with a magnet positioned adjacent the skin surface so as to align the housing with a needle being inserted into the septum.

19. A method of accessing a port implanted in tissue, comprising:

positioning a magnet adjacent to a skin surface, the magnet attracting a magnetic portion of a housing disposed beneath the skin surface and movably coupled to a base anchored to tissue to position a septum formed on the housing in a desired position.
