Heart anchor positioning devices, methods, and systems for treatment of congestive heart failure and other conditions
First Claim
1. A heart anchor positioning device comprising:
- a device body;
an elongate shaft having a proximal end that is coupled with the device body and a distal end and a lumen extending between the proximal end and the distal end, wherein a tension member is insertable through the lumen to enable the device to be advanced over the tension member so that the distal end is insertable within a body adjacent the heart while the device body is positioned outside of the body;
an anchor coupling mechanism positioned at the distal end of the elongate shaft, the anchor coupling mechanism being configured to engage a heart anchor to move the heart anchor distally along the tension member and into engagement with a first wall of the heart to urge the first wall toward a second wall of the heart, the anchor coupling mechanism being configured to lock the heart anchor to inhibit proximal movement of the heart anchor along the tension member, the anchor coupling mechanism being further configured to apply a pulling force to unlock the heart anchor to enable proximal movement of the heart anchor; and
a tension indicating mechanism that is configured to indicate a force being applied to the heart anchor by the device.

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.
