摘要：
A sphincter augmentation device includes a plurality of interlinked bodies and a pair of device ends configured to releasably couple together to secure the bodies in a loop formation sized to fit around an internal anatomical passageway of a patient. The device further includes a plurality of resilient members, with each resilient member extending between an adjacent pair of the bodies. The resilient members are configured to elastically deform to permit the device to transition between a radially contracted state and a radially expanded state. The resilient members bias the device toward the radially contracted state in which the device exerts an inwardly directed force on the anatomical passageway to selectively limit passage of fluids therethrough. The device further includes an expansion limiting member that extends between and is slidably received by an adjacent pair of the bodies, and is configured to limit radial expansion of the device.
