Claim 9:
10. A heart anchor positioning system comprising:
a tension line;
a heart anchor including a first surface configured to abut a wall of a heart, an opening through the surface and through which extends the tension line, and a cam component adjacent the opening, configured to grip the tension line when actuated and on a second side of the heart anchor opposite to the first side;
an elongate shaft including a lumen configured to receive the tension line, wherein a distal end of the elongate shaft is configured to releasably engage the cam component of the heart anchor and releasably grasp the heat anchor to apply an anchor force to press the heart anchor against the wall of a heart;
an anchor coupling mechanism at the distal end of the elongate shaft and configured to releasably grasp to the heart anchor and actuate the cam component of the heart anchor, wherein the anchor coupling mechanism is configured push and pull the heart anchor along the tension member, 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, and
a device body including a passage configured to receive the elongate shaft, a visual indicator configured to indicate a force applied by the elongate shaft to press the heart anchor while the heart anchor is in a variable force mode, and an actuation mechanism;
wherein the actuation mechanism is manually operated and configured to actuate the cam component to switch the heart anchor from the variable force mode during which the elongate shaft slides the heart anchor over the tension line into engagement with the wall of a heart, to a fixed force mode in which the heart anchor is fixed to the tension line.
