Abstract

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. The elongated member has a compressible ventral surface and a substantially rigid dorsal periphery, wherein the elongated member includes a fluid bladder positioned along the ventral surface. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. Alternate embodiments are also disclosed.
