Claim:
1. A cardiac support device comprising: a compliant and elastic jacket configured to be implanted on a heart using a minimally invasive approach and to become attached to the heart by tissue fibrosis, the jacket having a base end and an apex end, the jacket having an upper edge at the base end and being circumferentially closed between the base end and the apex end, the jacket configured for surrounding at least a lower portion of the heart and for constraining expansion of the heart, the jacket having an opening at the base end for positioning the base end in an atrial-ventricular groove of the heart, the jacket being formed from knit, open-cell material, the jacket having a channel extending circumferentially around the base end such that the channel defines the upper edge at the base end; and an elastic attachment band disposed within the channel and extending circumferentially around the base end of the jacket, the elastic attachment band configured to be positioned in the atrial-ventricular groove such that the elastic attachment band self-secures the jacket to the heart by applying a force that engages and holds the base end of the jacket in the atrial-ventricular groove of the heart during expansions and contractions of the heart, wherein the elastic attachment band comprises a polymer band.
