Abstract
An anchor is shaped to define a helix. A deployment tool is reversibly coupled to the anchor, and includes a lance. The deployment tool is configured to transluminally advance the anchor to the heart, and to stabilize the anchor at the tissue by driving the lance into the tissue. The deployment tool is also configured to anchor the anchor to the tissue, for example, by driving the tissue-penetrating helix into the tissue while the anchor remains stabilized at the tissue by the lance in the tissue, and to subsequently retract the lance from the tissue while leaving the anchor anchored to the tissue. Other embodiments are also described.
