1. A heart anchor positioning device comprising:
a device body including a lever mechanism configured to be manually actuated by a user during a procedure, wherein the procedure is to position a heart anchor into engagement with a heart;
an elongate shaft slidingly positioned within the device body, the elongate shaft having a proximal end, a distal end, and a lumen that extends between the proximal end and the distal end so that the heart anchor positioning device is configured to be advanced over a tension member, the distal end of the elongate shaft being configured to engage a heart anchor to apply an anchor force to the heart anchor as the heart anchor engages the heart; and
an anchor coupling mechanism at the distal end of the elongate shaft, wherein the anchor coupling mechanism releasably engages the heart anchor and is configured to push and pull the heart anchor along the tension member during a variable force mode of the heart anchor;
wherein the anchor coupling mechanism includes opposing hooks extending from the distal end of the elongate shaft and configured to releasably clamp onto the heart anchor,
wherein the heart anchor positioning device is configured to:
provide a visual indication of the anchor force applied to the heart anchor during the variable force mode; and
switch, by manual actuation of the lever mechanism, the heart anchor between the variable force mode that allows the heart anchor to slide axially along the tension member to engage the heart, and a set force mode that inhibits axial movement of the heart anchor along the tension member.
