Abstract
A radially-expandable stent () is shaped so as to define one or more tether interfaces (), a lower-securement portion (), and a higher-securement portion (). The lower-securement portion () extends (a) along at least a contiguous lower-securement axial segment () of the stent () and (b) circumferentially around a contiguous lower-securement circumferential portion () of the stent (), which lower-securement axial segment () and lower-securement circumferential portion () include the one or more tether interfaces (). The higher-securement portion () extends (a) along at least a contiguous higher-securement axial segment () of the stent () and (b) circumferentially around between 215 and 330 degrees of a circumference (C), at all circumferential locations other than those of the lower-securement circumferential portion (). The stent () is shaped so as to define a plurality of outward protrusions () at respective circumferential locations () around the higher-securement portion (), and not around the lower-securement portion (). One or more tethers () are coupled to the one or more tether interfaces (), respectively, and to one or more tissue anchors (), respectively.
