Abstract
An anchor deployment tool includes a flexible outer tube, within which is positioned a flexible inner shaft, and a rotating deployment element coupled to a distal end of the shaft. The tool is configured to provide an anchor storage area, which initially stores a plurality of tissue anchors, such that the inner shaft passes through channels of the anchors along entire longitudinal lengths of the anchors, and the anchors are within the outer tube. The rotating deployment element is configured to directly engage the anchors in the anchor storage area one at a time, advance each of the anchors while engaged in a distal direction, and deploy each of the anchors through the distal tube end and into tissue of a subject. Other embodiments are also described.
