Abstract
According to one embodiment, a heart anchor tensioning device includes a main body and an elongate shaft. A tension member or tether may be inserted through a lumen of the elongate shaft to allow the shaft to be advanced over the tension member and within a body while the main body is positioned outside of the body. The device also includes an anchor coupling mechanism that is configured to engage a heart anchor and move the heart anchor into engagement with a first wall of the heart. The anchor coupling mechanism is able to lock the heart anchor to inhibit proximal movement of the heart anchor along the tension member. The device further includes a tension indicating mechanism that provides an indication of a force being applied to the heart anchor by the device.
