Abstract
A method for improving leaflet prolapse and/or valve regurgitation associated with a heart valve involves delivering a spacer device into a ventricle of a heart using a delivery system comprising a catheter, fixing the spacer device to a wall of the ventricle, expanding the spacer device to reposition a papillary muscle disposed in the ventricle away from the wall, the papillary muscle being connected to a leaflet of an atrioventricular heart valve via chordae tendineae, and releasing the spacer device from the catheter.
