Apparatus and method for delivery of cardiac constraint jacket

A delivery apparatus for positioning a cardiac constraint jacket on a heart, the delivery apparatus comprising:

• a handle;
• a band having a first end fastened to the handle and a second end releasably fastened to the handle, wherein the second end of the band is tapered;
• and
• wherein a portion of the cardiac constraint jacket is configured to be attached on the band via the second end of the band for subsequent delivery and positioning of the cardiac constraint jacket on the heart.

A device for treating cardiac disease of a heart, the heart having a longitudinal axis from an apex to a base and having an upper and lower portion divided by an A-V groove, the heart including a valvular annulus adjacent the A-V groove and ventricular lower extremities adjacent the apex, the device comprising:

• A. a cardiac constraint jacket, the cardiac constraint jacket comprising:
• i. a volume between an open upper end and a lower end, the cardiac constraint jacket dimensioned for the apex of the heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart, the cardiac constraint jacket further dimensioned to have a longitudinal dimension between the upper and lower ends sufficient for the cardiac constraint jacket to constrain at least the lower portion of the heart;
• ii. a receiving member around the upper end of the jacket;
• iii. the cardiac constraint jacket adapted to be secured to the heart;
• B. A delivery apparatus for placing the cardiac constraint jacket on the heart, the delivery apparatus comprising:
• i. a handle;
• ii. a band having a first end fastened to the handle and a second end releasably fastened to the handle;
• and
• iii. releasing mechanism wherein the releasing mechanism fastens the second end of the band to the handle, wherein the receiving member of the cardiac constraint jacket is ibreaded on the band via the second end of the band for subsequent securing of the cardiac constraint jacket on the heart.
