Abstract:
A device for treating cardiac disease of a heart having a longitudinal axis from an apex to a base and having an upper and lower portion divided by an A-V groove, said heart including a valvular annulus adjacent said A-V groove and ventricular lower extremities adjacent said apex, the device comprising:A. a cardiac constraint jacket:i. said jacket defining a volume between an open upper end and a lower end, said jacket dimensioned for said apex of said heart to be inserted into said volume through said open upper end and for said jacket to be slipped over said heart, said jacket further dimensioned for said jacket to have a longitudinal dimension between said upper and lower ends sufficient for said jacket to constrain at least said lower portion of said heart;ii. said jacket adapted to be secured to said heart with said jacket having portions disposed on opposite sides of said heart between said valvular annulus and said ventricular lower extremities;B. a delivery device for placing said jacket on said heart; said delivery device including:i. a plurality of attachment locations, each of said attachment locations capable of releasably securing to separate positions surrounding a periphery of said open upper end of said jacket;ii. a proximal handle;iii. a control arrangement selectively movable between an open position and a closed position, said control arrangement connected to said attachment locations such that when said control arrangement is in said closed position said attachment locations are in a compact array to urge said open upper end of said jacket into a collapsed configuration and when said control arrangement is in said open position said attachment locations are in an open array to urge said open upper end of said jacket into an open configuration sufficient for said heart to be inserted into said volume through said open upper end and for said open upper end to be placed over said apex of said heart and for said jacket to be slipped over said heart.
