Abstract:
1. A method for inhibiting migration of anchors of a heart implant device adjacent walls of a heart within a patient body, the method comprising: positioning a first anchor in engagement with a first wall of the heart, the first anchor being coupled with a tension member; positioning a second anchor in engagement with a second wall of the heart, the second anchor being slidably coupled with the tension member so that the second anchor may slide proximally and distally along a length of the tension member; applying an anchor force between the tension member and the second anchor by engaging the second anchor with a tension device, the anchor force being applied so that the first anchor provides a force urging the first wall toward the second wall and the second anchor provides a force urging the second wall toward the first wall, wherein the tension device comprises a shaft extending from a proximal end to a distal end, a lumen through which the tension member is inserted, and a tube that is slidably disposed over the shaft, the tube including a compression spring and indicia that provide an indication of the anchor force applied being within a desired range, and wherein the anchor force is applied by tensioning a portion of the tension member extending proximally of the tension device; and securing the second anchor relative to the tension member while the anchor force is applied so as to restrict proximal movement of the second anchor along the tension member and maintain the anchor force.
