  • Patent number: 11517437
    Abstract: A cardiac device for implantation proximate an exterior of a heart, the cardiac device including an inflatable bladder including an inner wall and an outer wall, wherein the inner wall itself is more expandable than the outer wall itself such that the inflatable bladder itself is configured to deform substantially inwardly to exert localized pressure against a region of the heart when the inflatable bladder is positioned adjacent the region of the heart and inflated.

  • Publication number: 20220378579
    Abstract: 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.

  • Publication number: 20090270980
    Abstract: The various aspects of the invention pertain to devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other similar heart failure conditions. The devices and related methods of the present invention operate to assist in the apposition of heart valve leaflets to improve valve function. According to one aspect of the invention, a method improves the function of a valve of a heart by placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber.
