Methods and devices are provided for adjusting the height of devices in a gastric restriction system. In general, the methods and devices allow one or more implantable housings coupled to an implantable restriction device to have an adjustable height. The housing can include, for example, a fill port housing, a sensor housing, and any other type of housing that can be used in an implantable restriction system and desired to have an adjustable height. The housing can lower in profile over time, e.g., as the patient loses weight, thereby maintaining the housing in a generally predictable location where it can be found and accessed.
1. A method of forming a restriction in a patient, comprising: implanting a restriction device in a patient to form a restriction;implanting a housing coupled to the restriction device within the patient such that a base defining a distal external surface of the housing and a body defining a proxima
1. A method of forming a restriction in a patient, comprising: implanting a restriction device in a patient to form a restriction;implanting a housing coupled to the restriction device within the patient such that a base defining a distal external surface of the housing and a body defining a proximal external surface of the housing are spaced a distance apart from one another; andadjusting the distance between the proximal and distal external surfaces to lower a profile of the housing implanted within the patient, wherein adjusting the distance comprises changing a volume of fluid within a fluid-filled chamber extending between the base of the housing and the body of the housing to alter the distance between the base and the body, wherein changing the volume of the fluid within the fluid-filled chamber does not alter a volume of a second fluid within the restriction device or change an amount of restriction. 2. The method of claim 1, wherein the restriction device comprises a gastric band that is implanted around a patient's stomach. 3. The method of claim 1, wherein the restriction device is coupled to the housing by a catheter. 4. The method of claim 1, wherein adjusting the distance comprises causing the body of the housing to move relative to the base of the housing. 5. The method of claim 1, wherein adjusting the distance comprises inserting a needle through tissue and into a fill port formed in the housing, and changing the volume of fluid within the housing. 6. The method of claim 1, wherein the housing includes a pressure sensor that senses a pressure of fluid within the implantable restriction device and that communicates pressure data to an external monitor. 7. The method of claim 1, wherein implanting the housing comprises positioning the body of the housing a first distance from a skin surface of the patient, and securing the base of the housing to tissue of the patient a second distance from the skin surface, the second distance being greater than the first distance. 8. The method of claim 7, wherein adjusting the distance substantially maintains the body of the housing at the first distance from the skin surface, and causes the base of the housing to move toward the skin surface such that the second distance decreases. 9. The method of claim 1, wherein changing the volume of the fluid comprises removing an amount of the fluid from the fluid-filled chamber to decrease the distance between the base and the body. 10. A method of forming a restriction in a patient, comprising: implanting a restriction device in a patient to form a restriction;implanting a housing coupled to the restriction device within the patient such that a base defining a distal external surface of the housing and a body defining a proximal external surface of the housing are spaced a distance apart from one another;adjusting the distance between the proximal and distal external surfaces to lower a profile of the housing implanted within the patient; andadjusting a volume of fluid within the restriction device to change an amount of restriction, wherein adjusting the volume of the fluid within the restriction device does not alter the distance between the proximal and distal external surfaces. 11. A method of forming a restriction in a patient, comprising: implanting a gastric band around a patient's stomach to restrict fluid flow through the stomach, the gastric band having a catheter extending therefrom, the catheter extending between the gastric band and a housing that is implanted in an abdomen of the patient beneath a tissue surface such that a first fluid can flow through the catheter between the gastric band and the housing; andchanging a volume of a second fluid within the housing to move a body of the housing relative to a base of the housing and thereby adjust a height of the housing, wherein changing the volume of the second fluid does not alter an amount of the first fluid that can flow through the catheter between the gastric band and the housing. 12. The method of claim 11, wherein changing the volume of the second fluid comprises removing an amount of the second fluid from the housing such that the height of the housing decreases. 13. The method of claim 12, wherein removing the amount of the second fluid causes the base to occupy an internal space in the housing formerly containing the removed amount of the second fluid. 14. The method of claim 12, wherein removing the amount of the second fluid causes the base and the body to lock together. 15. The method of claim 11, further comprising changing a volume of the first fluid within the gastric band to change an amount of restriction, wherein changing the volume of the first fluid does not alter the volume of the second fluid within the housing. 16. The method of claim 11, wherein the first fluid is contained within a reservoir of the housing, the second fluid is contained within an internal cavity of the housing, and the reservoir and the internal cavity are not in fluid communication with one another.
