First Claim
1. A system comprising:
- an anchor driver;
a housing, shaped to define a channel having an anchor-storage zone and a proximal opening configured to provide access for the anchor driver to the anchor-storage zone;
a tissue anchor, stored in the anchor-storage zone and slidable through the channel; and
a retaining member;
having a retaining state in which the retaining member is configured to retain the tissue anchor in the anchor-storage zone, andbeing 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 being greater than a pre-determined threshold force;
wherein the tissue anchor has a mass, and the retaining member is configured such that the threshold force, measured in grams force, is more than 1000 times greater than the mass of the tissue anchor, measured in grams.

Abstract
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.
