Abstract
Apparatus is provided, including a radially-expandable percutaneous implant, a tissue anchor, and a connecting element shaped so as to provide an annular loop surrounding a proximal portion of the tissue anchor in a manner which enables rotation of the anchor about a central longitudinal axis thereof when surrounded by the annular loop. The apparatus also includes a flexible longitudinal member coupled at a first portion thereof to at least a portion of the percutaneous implant and at a second portion to the connecting element. The annular loop of the connecting element facilitates rotation of the tissue anchor about the central longitudinal axis such that the anchor can rotate about the central longitudinal axis with respect to the annular loop, the flexible longitudinal member, and the percutaneous implant. Other applications are also described.
