An apparatus for delivering a cardiac harness onto a heart includes an elongate body and a plurality of elongate push rods longitudinally movable with respect to the elongate body. The elongate body has a tubular housing that is sized to contain the cardiac harness and has a compressible cross-sectional shape. The cardiac harness is releaseably attached to the push rods such that advancement of the push rods in a distal direction moves the cardiac hearness from a compacted configuration in the housing to an expanded configuration outside the housing. The housing may include a plurality of flexible slats that extend longitudinally such that the housing may be compressed to a reduced cross-sectional shape to allow it to advance through a minimally invasive surgical entry path to the heart. The slats may include curved end portions for locking underneath a pericardial sac surrounding the heart.
