 the jacket has a first elasticity; and   the attachment structure has a second elasticity that is less than the first elasticity.   
   
   
       10 . The cardiac support device of  claim 1  wherein the attachment structure includes one or more undulating resilient elements. 
   
   
       11 . The cardiac support device of  claim 10  wherein the one or more undulating resilient elements include one or more metal elements. 
   
   
       12 . The cardiac support device of  claim 10  wherein the one or more undulating resilient elements includes one or more polymer elements. 
   
   
       13 . The cardiac support device of  claim 10  wherein the one or more undulating resilient elements includes one or more bio-resorbable elements. 
   
   
       14 . The cardiac support device of  claim 1  wherein the attachment structure includes a polymer structure. 
   
   
       15 . The cardiac support device of  claim 1  wherein the attachment structure includes a metal structure. 
   
   
       16 . The cardiac support device of  claim 1  wherein the attachment structure includes shape memory material structure. 
   
   
       17 . The cardiac support device of  claim 1  wherein the attachment structure includes bio-resorbable material structure. 
   
   
       18 . The cardiac support device of  claim 1  wherein the attachment structure extends circumferentially around the jacket. 
   
   
       19 . The cardiac support device of  claim 18  wherein the attachment structure extends completely around the jacket. 
   
   
       20 . The cardiac support device of  claim 18  wherein the attachment structure extends partially around the jacket. 
   
   
       21 . The cardiac support device of  claim 18  wherein the attachment structure includes a plurality of segments at spaced-apart locations. 
   
   
       22 . The cardiac support device of  claim 1  wherein the attachment structure includes one or more rings. 
   
   
       23 . The cardiac support device of  claim 1  wherein the attachment structure includes a helical coil. 
   
   
       24 . The cardiac support device of  claim 1  wherein the attachment structure includes a plurality of rings connected by links. 
   
   
       25 . The cardiac support device of  claim 1  wherein the attachment structure includes a hoop having two free ends. 
   
   
       26 . The cardiac support device of  claim 1  wherein the attachment structure includes a single elastomeric band. 
   
   
       27 . The cardiac support device of  claim 26  wherein the elastomeric band includes apertures. 
   
   
       28 . The cardiac support device of  claim 26  wherein the elastomeric band extends completely around the jacket. 
   
   
       29 . The cardiac support device of  claim 26  wherein the elastomeric band extends partially around the jacket. 
   
   
       30 . The cardiac support device of  claim 1  wherein the attachment structure includes a plurality of spaced-apart elastomeric bands. 
   
   
       31 . The cardiac support device of  claim 1  wherein the attachment structure includes one or more filamentary elastomeric bands. 
   
   
       32 . The cardiac support device of  claim 31  wherein the attachment structure further includes a plurality of pads.
