    摘要: This invention is directed to a partitioning device for separating a patient's heart chamber into a productive portion and a non-productive portion which is suitable for treating patients with heart disease, particularly congestive heart failure. The partitioning device has a reinforced membrane with outwardly biased members to help seal the periphery of the membrane against the wall of the patient's heart chamber. In one embodiment, the outwardly biased member is an expansive strand that extends between adjacent ribs of an expandable frame which reinforces the membrane. In another embodiment, the outwardly biased member is a hydrophilic body such as foam which swells upon contact with body fluid such as blood in the heart chamber. The reinforced membrane has a central hub with a distally extending support stem with a plurality of feet which extend radially from a centerline axis and preferably have ends that are aligned in a common plane. The ends of the pods which extend radially away from the centerline axis may be interconnected by flexible struts and/or webs.

    摘要: This invention is directed to a partitioning device for separating a patient's heart chamber into a productive portion and a non-productive portion. The device is particularly suitable for treating patients with congestive heart failure. The partitioning device has a frame-reinforced, expandable membrane which separates the productive and non-productive portions of the heart chamber. The proximal ends of the ribs of the frame have tissue penetrating elements about the periphery thereof which are configured to penetrate tissue lining the heart wall at an angle approximately perpendicular to a longitudinal axis of the partitioning device. The partitioning device has a hub with a non-traumatic distal end to engage the ventricular wall.

    摘要: This invention is directed to a device and method of using the device for partitioning a patient's heart chamber into a productive portion and a non-productive portion. The device is particularly suitable for treating patients with congestive heart failure. The device has an inflatable partitioning element which separates the productive and non-productive portions of the heart chamber and in some embodiments also has a supporting element, which may also be inflatable, extending between the inflatable partitioning element and the wall of the non-productive portion of the patient's heart chamber. The supporting element may have a non-traumatic distal end to engage the ventricular wall or a tissue penetrating anchoring element to secure the device to the patient's heart wall.

    摘要: A method is provided for stimulating nerve growth, especially for nerve regeneration after damage to the nerve. The method comprises: applying thermal energy to one or more nerve segments adjacent a damaged region of the nerve, such that nerve fibers from the treated adjacent segment are stimulated to grow and extend toward the damaged region. The method may be used to enhance mechanical stimulative effect at a terminus of a severed nerve or a region of nerve injured by crush or other physical forces. The method may also be used to treat nerve segments retrograde up the nerve fiber and to increase the response of the injured nerve to regrowth and extension rapidly. An apparatus for delivery of thermal energy to the distal terminus of the severed nerve or region is disclosed. Thermal conductive or electromagnetic energy is delivered through a probe having a handle and a shaft. An energy delivery portion of the probe is configured to apply thermal energy to the distal segments of the severed nerve to promote rapid and more extensive growth of the nerve cells.
