The invention provides a sphincter augmentation device which includes a plurality of bodies and a flexible band coupled with the bodies. The bodies define a first circumferential portion of the device and are magnetically biased toward one another. The flexible band defines a second circumferential portion of the device such that the bodies are arranged non-axisymmetrically about a central axis of the device. The device is sized to be positioned around a human urethra so that the bodies and the flexible band bear inwardly against the urethra. The device is configured to transition between a radially expanded state and a radially contracted state by the magnetic bias of the bodies to constrict the urethra. 本发明提供了一种括约肌增强装置，该括约肌增强装置包括多个主体以及与该主体联接的柔性带。该主体限定该装置的第一圆周部分并且朝向彼此磁性偏置。该柔性带限定该装置的第二圆周部分，使得该主体围绕该装置的中心轴线非轴对称地布置。该装置的尺寸被设定成围绕人尿道定位，使得该主体和该柔性带向内抵靠该尿道。该装置被构造成通过该主体的磁性偏置在径向扩张状态与径向收缩状态之间转变，以收缩该尿道。
