Abstract
A highly compliant and elastic cardiac support device is provided. The device is constructed from a biocompatible material is applied to an external surface of a heart. The device can be used to resist dilatation of the heart, to provide acute wall support, or to enhance reduction in the size of the heart using stored potential energy, without interfering with systolic contraction.
Claims57
A device for treating diseases of a heart, said device comprising:
- a biocompatible material sized to surround an external surface of said heart;
- said material having an elasticity and a compliance reflecting a tendency to return to a rest state and an ability to deform under strain, respectively;
- said elasticity and compliance selected for said material to be placed surrounding said external surface with a tightness selected for energy to be stored in said material to assist chronic remodeling of said heart and to avoid significant acute resistance to diastolic filling of said heart.
A method for treating diseases of a heart, said method comprising:
- surgically accessing the heart;
- applying a cardiac support device to an external surface of the heart where said cardiac support device includes:
- a biocompatible material sized to surround an external surface of said heart;
- said material having an elasticity and a compliance reflecting a tendency to return to a rest state and an ability to deform under strain, respectively;
- said elasticity and compliance selected for said material to be placed surrounding said external surface with a tightness selected for energy to be stored in said material to assist chronic remodeling of said heart and to avoid significant acute resistance to diastolic filling of said heart.
