Abstract
A sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.
