Abstract

Various exemplary methods are disclosed for implanting a restriction device for forming a restriction in a patient. The methods can be used with a variety of restriction devices, but in an exemplary embodiment the methods are used for implanting a gastric restriction device.

Claims

1. A method for implanting a restriction system, comprising:

forming a primary pathway through a skin incision;

coupling a catheter exiting through the skin incision to a housing such that the housing is coupled, via the catheter, to a restriction device implanted to form a restriction;

forming a tunnel extending from the primary pathway to a secondary pathway;

positioning the housing within the tunnel;

advancing the catheter from one of the primary pathway and the secondary pathway, through the tunnel, to the other one of the primary pathway and the secondary pathway; and

coupling the catheter to the housing after advancing the catheter.

2. The method of claim 1, wherein the tunnel extends transverse to a longitudinal axis of the pathway.

3. The method of claim 1, wherein forming the tunnel comprises forming a finger tunnel.

4. The method of claim 1, wherein forming the tunnel comprises inserting an elongate member into the pathway and manipulating the elongate member to form a tunnel extending from the pathway.

5. The method of claim 1, wherein the tunnel is formed adjacent to a fascia layer.

6. The method of claim 1, wherein the housing comprises a first housing that is coupled to a second housing, and wherein the method further comprises positioning the second housing adjacent to the pathway.

7. The method of claim 1, wherein positioning the housing within the tunnel comprises retracting the catheter into the tunnel to pull the housing through one of the primary pathway and the secondary pathway and into the tunnel.

8. The method of claim 1, wherein the pathway extends from a skin incision and into a body cavity and the method further comprises advancing the restriction device through the pathway and into the body cavity.

9. The method of claim 1, wherein the housing is in fluid communication with the restriction device.

10. The method of claim 1, wherein the restriction device includes a sensor that measures at least one physiological parameter.

11. The method of claim 10, wherein the sensor comprises a pressure sensor.

12. A method for implanting a restriction system, comprising:

advancing a restriction device through a pathway extending from a skin incision into a body cavity;

forming a single connection between a catheter coupled to the restriction device and one of a first housing and a second housing, the first and second housings being coupled to one another by a connector extending therebetween; and

implanting the first and second housings in tissue, the first housing being implanted in a tunnel extending from the pathway and adjacent to a fascia layer, and the second housing being implanted in the pathway at an offset location.

13. The method of claim 12, wherein, when the restriction device is advanced through the pathway and into a body cavity, the catheter extends through the pathway and exits the skin incision.

14. The method of claim 12, wherein the pathway comprises a first pathway, and wherein the tunnel extends from the first pathway to a second pathway, and implanting the first and second housings comprises retracting the catheter into the tunnel.

15. The method of claim 14, wherein the catheter is advanced from the first pathway to the second pathway prior to forming a single connection between the catheter and one of the first and second housings.

16. The method of claim 12, wherein the tunnel is formed by advancing a finger through tissue adjacent to the pathway.

17. The method of claim 12, wherein the tunnel is formed by inserting an elongate member into the pathway and manipulating the elongate member to extend transverse to a longitudinal axis of the pathway.

18. A method of implanting a restriction system, comprising:

advancing a restriction device through a primary pathway extending from a skin incision to a body cavity to position the restriction device around an organ to be restricted;

forming a tunnel between the primary pathway and a secondary pathway;

advancing the trailing end of a catheter coupled to the restriction device through the primary pathway, across the tunnel, and through the secondary pathway such that the trailing end of the catheter exits the secondary pathway;

coupling the trailing end of the catheter to a housing; and

implanting the housing in tissue;

wherein the trailing end of the catheter exits from the skin incision when the restriction device is advanced through the primary pathway.

19. The method of claim 18, wherein implanting the housing comprises retracting the catheter to position the housing within the tunnel, and implanting the housing in the tunnel.

20. The method of claim 19, wherein the catheter is retracted by pulling on a portion of the catheter extending from the primary pathway.

21. The method of claim 18, wherein the housing comprises a sensor housing that is coupled to a fill port, and wherein the method further comprises implanting the fill port in tissue.
