Patent attributes
Apparatus is provided, the apparatus comprising (i) a housing (22, 222), shaped to define a channel (24, 224) having an anchor-storage zone (26, 226) and an opening (28, 228) configured to provide access for an anchor driver (60) to the anchor-storage zone; (ii) a tissue anchor (40), stored in the anchor-storage zone and slidable through the channel; and (iii) a retaining member (30, 230). The retaining member (a) has a retaining state in which the retaining member is configured to retain the tissue anchor in the anchor-storage zone, and (b) is configured, by moving in response to a proximally-directed force applied to the tissue anchor, to allow the tissue anchor to leave the anchor-storage zone in response to the proximally-directed force. The proximally-directed force is greater than a pre-determined threshold force. Other embodiments are described.
