A system for treating mitral valve regurgitation comprises tensioning device 110 slidably received within delivery catheter 120. The tensioning device includes tether 112 linking proximal anchoring member 111 and distal anchoring member 113. At least one of the anchoring members 111 includes an elastic portion that flexes in response to a heartpulsebeat when tensioning device 110 is positioned across a chamber of a heart. Tether 112 includes at least one locking member 116, 514 initially positioned between the anchoring members 111. |
