PERCUTANEOUS TISSUE ANCHOR TECHNIQUES
First Claim
1. A method, comprising:
- transluminally advancing a distal portion of an anchor-manipulation tool to an anchor that is intracorporeally implanted in a subject, a tissue-coupling element of the anchor being anchored within tissue of the subject, and the anchor-manipulation tool including;
at the distal portion, an anchor-engaging element and an actuator, the actuator configured to actuate the anchor-engaging element,at an extracorporeal proximal portion of the anchor-manipulation tool, a controller, anda flexible longitudinal member extending between the proximal portion and the distal portion;
subsequently, engaging the anchor-engaging element with an eyelet defined by a head of the anchor;
subsequently, using the controller to transition the tool into an articulatably-coupled state in which;
the eyelet at least in part inhibits movement of the anchor-engaging element away from the anchor, andthe distal portion of the anchor-manipulation tool is deflectable with respect to the anchor; and
subsequently, de-anchoring the anchor by removing the tissue-coupling element from the tissue by using the anchor-manipulation tool to apply a de-anchoring force to the eyelet.

Abstract
An example anchor-manipulation tool includes (i) at a distal portion of the tool, an anchor-engaging element and an actuator, (ii) at an extracorporeal proximal portion of the tool, a controller, and (iii) a flexible longitudinal member extending between the proximal portion and the distal portion. The distal portion of the tool can be transluminally advanced to an anchor that is intracorporeally implanted in a subject. Subsequently, the anchor-engaging element can be engaged with an eyelet defined by a head of the anchor. Subsequently, the controller can be used to transition the tool into an articulatably-coupled state in which: (i) the eyelet at least in part inhibits movement of the anchor-engaging element away from the anchor, and (ii) the distal portion of the anchor-manipulation tool is deflectable with respect to the anchor. Subsequently, the anchor can be de-anchored by using the anchor-manipulation tool to apply a de-anchoring force to the eyelet.
