1. A method for use with (a) an implant and (b) a single elongate element that interacts with the implant, the implant including:
a central body, and
anchoring arms that extend proximally from a downstream end portion of the implant and that are movable with respect to an upstream end portion of the implant,
the method comprising:
advancing a catheter to a heart of a subject;
via the catheter, advancing the implant into the heart;
implanting the implant at a native atrioventricular valve of the heart that is disposed between an atrium of the heart and a ventricle of the heart, by:
positioning: (i) the anchoring arms of the implant in the ventricle of the heart, (ii) the central body of the implant between leaflets of the native atrioventricular valve, and (iii) a distal end of the single elongate element into the ventricle; and
pulling on the single elongate element while the distal end of the single elongate element is (1) distal to a distal end of the central body and (2) within the ventricle, and, by the pulling, applying a proximally-directed force to the anchoring arms to move distal ends of the anchoring arms axially with respect to the upstream end portion of the implant while the distal ends of the anchoring arms remain radially fixed with respect to a central longitudinal axis of the implant; and
removing the single elongate element from the subject.
