A cardiac constraint jacket is formed of flexible material defining a volume between an open upper end and a lower end. The jacket is dimensioned for an apex of a patient's heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart. The jacket includes a receiving member along its upper end for engagement to a delivery apparatus, the apparatus used in positioning the jacket on the heart. The delivery apparatus includes a handle and a band. The band is generally hoop shaped having a first end and a second end attached to the handle, the first end fixedly attached to the handle and the second end releasably attached to the handle. Alternatively, the first end can be attached to a releasable end cap of the handle. In use, the second end of the band is released from the handle and inserted into the jacket receiving member. The jacket is threaded onto the band and the band end re-attached to the handle. The band is deformed to fit over the circumference of the heart, and then manipulated to position the jacket on the heart. Once positioned, the band is released from the handle and removed from the jacket receiving member.
