Off-Center Tissue Anchors

Abstract: a tissue anchor () includes a shaft (), a tissue-coupling element (), and a flexible elongate tension member (). the tissue-coupling element () includes a wire (), which is shaped as an open loop () having more than one turn when the tissue anchor () is unconstrained. the tension member () includes a distal portion () that is fixed to a site () on the open loop (), a proximal portion (), which has a longitudinal segment () that runs alongside at least a portion () of the shaft (), and a crossing portion (), which (i) is disposed between the distal and the proximal portions () along the tension member (), and (ii) crosses at least a portion of the open loop () when the tissue anchor () is unconstrained. the tissue anchor () is configured to allow relative axial motion between the at least a portion () of the shaft () and the longitudinal segment () of the proximal portion () of the tension member () when the tissue anchor () is unconstrained.
