  • Cardiac harness for treating congestive heart failure and for defibrillating and/or pacing/sensing
    Patent number: 7155295
    Abstract: A system for treating the heart includes a cardiac harness associated with a cardiac rhythm management devise which includes at least electrodes and a power source. The cardiac harness applies a compressive force on the heart during diastole and systole. The electrodes will deliver an electrical shock to the heart for defibrillation and/or can be used for pacing/sensing. The cardiac harness and electrodes are delivered and implanted on the heart by minimally invasive access.

  • Method of manufacturing a cardiac harness
    Patent number: 7124493
    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.

  • Cardiac harness
    Patent number: 7097613
    Abstract: A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness is configured so that the variation of load as a function of expansion through a selected range of expansion is represented generally in the form y=ax+b, and the value of “a” does not increase as the percent expansion increases.

  • Cardiac harness having leadless electrodes for pacing and sensing therapy
    Publication number: 20060009831
    Abstract: A system for treating the heart includes a cardiac harness associated with a cardiac rhythm management device which does not have a lead system. Multiple pacing and sensing electrodes are attached to the cardiac harness but not to the cardiac rhythm management device. The cardiac harness applies a compressive force on the heart during diastole and systole, and the cardiac rhythm management device will deliver an electrical pulse to the pacing electrodes on the heart for pacing/sensing therapy. The cardiac harness and cardiac rhythm management device are both delivered and implanted by minimally invasive access.

  • Expandable stents and method for making same
    Publication number: 20050192663
    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements. The individual radially expandable cylindrical elements consist of ribbon-like material disposed in an undulating pattern. Portions of the expanded stent project outwardly into engagement with the vessel wall to more securely attach the stent.

  • Cardiac harness delivery device and method
    Publication number: 20050182290
    Abstract: The apparatus includes and elongate body having a proximal portion and a distal portion. The body includes a cavity sized to contain a 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 each of the push rods such that advancement of the push rods in a distal direction moves the harness from a compacted configuration, within the cavity, to an expanded configuration, outside the cavity. The apparatus also includes a releasing member for releasing the connections between the push rods and the harness upon actuation of the releasing member by a user.

    Publication number: 20050171589
    Abstract: A system for treating the heart includes a cardiac harness associated with a cardiac rhythm management device which includes at least one electrode and a conductor lead that is connected to a power source. The electrodes include lumens for the removable insertion of a stylet or guide wire, which will provide the electrodes and the cardiac harness with the necessary columnar strength to push the cardiac harness over the heart. The stylet or guide wire also can be used to steer or lead the cardiac harness into position around at least a portion of the heart.
