Abstract:
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; and adjusting 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.
