  • Publication number: 20120178988
    Abstract: A surgical device for reinforcing the pericardial sac surrounding the heart to assist in the treatment of congestive heart failure includes an enclosure having an interior and an exterior. The interior surface limits adhesions or accepts ingrowth with the myocardial tissue of the epicardium. The exterior surface is adapted to adhere to or otherwise attach to the pericardium to provide reinforcement.

  • Patent number: 7354396
    Abstract: A device for supporting or constraining at least some part of the epicardial surface of the heart during a portion of the heartbeat, such as diastole is used to assist in the treatment of congestive heart failure. The device comprises an enclosure having an interior and an exterior. An interior surface is preferably made in such a way that it tends not to or does not form adhesions with or accept ingrowth with the myocardial tissue of the epicardium. The device may comprise at least on rib-like structural member.
    Type: Grant

  • Patent number: 7060023
    Abstract: This is a surgical device and a method of using it. In particular, the device is one for reinforcing the pericardial sac surrounding the heart to assist in the treatment of congestive heart failure. The device, generically, is an enclosure having an interior and an exterior. The interior surface is made in such a way that it tends not to or does not form adhesions with or accept ingrowth with the myocardial tissue of the epicardium. The exterior surface of the device, in contrast, is adapted to adhere to or to ingrow with or otherwise attach sufficiently to the pericardium so that it reinforces that membrane or structure. The nature of the device is that it tends not to allow the pericardium to expand further with time. The device, after complete deployment, should envelope some measure of pericardial fluid in its interior separating it from the epicardial surface. This device helps to prevent further declination of the heart during congestive heart failure.

  • Patent number: 6695769
    Abstract: This is a surgical device and a method of using it. In particular, the device is one for supporting or constraining at least some part of the epicardial surface of the heart during a portion of the heartbeat, in particular during diastoly. This device may be used to assist in the treatment of congestive heart failure. The device, generically, is an enclosure having an interior and an exterior. The interior surface is preferably made in such a way that it tends not to or does not form adhesions with or accept ingrowth with the myocardial tissue of the epicardium. The device preferably has at least on rib-like structural member. The rib component may extend from end-to end or preferably extends helically around the heart, preferably with at least one revolution. The device may be configured to be self-adherent, i.e., preferably adherent only to itself, and to form a unitary support in the pericardial space after installation.
