  • Expandable cardiac harness for treating congestive heart failure
    Patent number: 7276022
    Abstract: A cardiac harness for treating congestive heart failure is disclosed. The harness applies elastic, compressive reinforcement on the left ventricle to reduce deleterious wall tension and to resist shape change of the ventricle during the mechanical cardiac cycle. Rather than imposing a dimension beyond which the heart cannot expand, the harness provides no hard limit over the range of diastolic expansion of the ventricle. Instead, the harness follows the contour of the heart throughout diastole and continuously exerts gentle resistance to stretch. Also disclosed is a method of delivering the cardiac harness to the heart minimally invasively.

  • Heart failure treatment device and method
    Patent number: 7276021
    Abstract: A method and apparatus for treating heart failure is configured to be placed about at least a portion of a patient's heart to apply a mild compressive force on the heart over a range of elastic deformation of the apparatus. The apparatus can be shifted to second range of deformation. In some embodiments, the apparatus is shifted to the second range of deformation by application of a stimulus or alteration of environmental conditions beyond a threshold level.

  • Cardiac harness delivery device and method of use
    Patent number: 7229405
    Abstract: A delivery system for delivering and mounting a cardiac harness on a heart including an elongate body having a proximal portion and a distal portion. The body includes a cavity sized to contain the cardiac harness in a compacted configuration and also includes a plurality of elongate push rods movable with respect to the body. The cardiac harness is releasably connected to the push rods such that, advancement of the push rods in a distal direction moves the cardiac harness from a compacted configuration, within the cavity, to an expanded configuration, outside the cavity. The push rods are configured to have varying stiffness along their length to provide sufficient flexibility to bend up to 90° to advance the cardiac harness onto the heart.

  • Cardiac harness assembly for treating congestive heart failure and for pacing/sensing
    Publication number: 20070106336
    Abstract: A pace/sense electrode is associated with a cardiac harness for treating the heart. The pace/sense electrode is positioned on the epicardial surface of the heart, preferably under the cardiac harness, to provide pacing and sensing therapy to the heart. Compressive forces from the cardiac harness serve to hold the pace/sense electrode in place and to push the electrode into direct contact with the epicardial surface of the heart. Various means are provided for placing the pace/sense electrode under the cardiac harness in a minimally invasive procedure.

  • Apparatus and method of delivering biomaterial to the heart
    Publication number: 20070100199
    Abstract: A biomaterial for treating or preventing congestive heart failure is injected into the intrapericardial space of a patient's heart to apply a mild compressive force on the heart. A volume of biomaterial is placed in the intrapericardial space by an injection needle or catheter, adjacent at least the left ventricle, so that the biomaterial applies a compressive force on the myocardium to relieve cardiac wall tension during at least a portion of the cardiac cycle.
