Abstract
A method and apparatus for treating congestive heart disease and related cardiac complications such as valvular disorders and includes a constraining device placed on the heart. The constraining device is a jacket of flexible material of knit construction defining a volume between an open upper end and a lower end. The jacket is 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 jacket is further dimensioned for the jacket to have a longitudinal dimension between the upper and lower ends sufficient for said jacket to constrain said lower portion of the heart. The jacket adapted to be adjusted on the heart to snugly conform to an external geometry of the heart to constrain circumferential expansion of the heart beyond. The jacket includes an indicator for indicating when the jacket is adjusted on the heart to a desired degree of tensioning
