Abstract
Abstract A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary “jacket” that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material. Preferably, the device includes a first adjustment mechanism configured to adjust a tension of the material covering the right ventricle and a second adjustment mechanism configured to adjust the tension of the material covering the left ventricle such that the tension of the material covering the left ventricle can be different than the tension of the material covering the right ventricle.
