Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

Cardiac treatment system and method

A bi-leaflet prosthetic heart valve, comprising an annular body having an upstream edge, a downstream edge and a passageway therebetween includes first and second leaflets pivotally mounted in the annular body. Each leaflet has an upstream edge, a downstream edge and a leaflet length therebetween. First and second pivot axes associated respectively with the first and second leaflets are provided and each leaflet rotates about its respective pivot axes between an open position allowing blood flow through the passageway of the annular body and a closed position blocking blood flow. The valve is configured such that the leaflets have an angle in the naturally open position of more than about 85&deg;.
