Abstract
Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.
