  • Expandable stents and method for making same
    Patent number: 6908479
    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 for treating congestive heart failure and for defibrillating and/or pacing/sensing
    Publication number: 20050119717
    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.

  • Expandable cardiac harness for treating congestive heart failure
    Publication number: 20050107661
    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 delivery device and method
    Publication number: 20050090707
    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.

  • Self-anchoring cardiac harness
    Publication number: 20050054892
    Abstract: A self-anchoring cardiac harness is configured to fit at least a portion of a patient's heart and includes a tissue engaging element for frictionally engaging an outer surface of a heart. The engaging element produces sufficient friction relative to the outer surface of the heart, so that the harness does not migrate substantially relative to the heart. There is enough force created by the engaging element that there is no need to apply a suture to the heart in order to retain the cardiac harness. Further, the engaging element is adapted to engage the outer surface of the heart without substantially penetrating the outer surface.

  • Heart failure treatment device and method
    Publication number: 20050033109
    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.

  • Multi-panel cardiac harness
    Publication number: 20040249242
    Abstract: A cardiac harness configured to be fit around at least a portion of a patient's heart, including a conductive material that is coated with a dielectric coating to electrically insulate at least the heart tissue from the conductive material. The cardiac harness applies a compressive force on the heart during diastole and systole. The cardiac harness includes an arrangement that provides no electrical continuity circumferentially about the harness, so that if an electric current created by a defibrillation device is applied to a patient who has a harness that is placed on their heart, the electric current will pass through the heart unimpeded instead of being conducted around the heart through the harness.
