摘要：
An apparatus for regulating the functioning of a patients organ or duct includes an elongated member having a first end and a second end. 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 symmetrical drive system including a drive element associated with and engaging the tension element for causing the tension element to control the tension applied by the elongated member against a patients body organ or duct is further provided. In accordance with an alternate embodiment an apparatus for regulating the functioning of a patients organ or duct including an elongated member having a first end and a second end. 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. The tension element is composed of a flexible first member and a flexible second member, wherein the flexible first member is movable relative to the flexible second 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 patients body organ or duct.
