    摘要： 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 system and method for partitioning a patient's heart chamber into a productive portion and a non-productive portion which are particularly suitable for treating patients with congestive heart failure. The partitioning system has a plurality of partitioning devices with reinforced, expandable membranes which separate the productive and non-productive portions of the heart chamber. When deployed within the patient's heart chamber, the second partitioning device is off-set from the deployed first partitioning device to cover a region of the wall defining the patient's heart chamber which is not covered by the first partitioning device. The multiple partitioning devices may be independent from each other or may be interconnected, e.g. a tether or strand.

    摘要： A device and method for creating a connection with the left ventricle of a heart are provided. A seal member capable of moving between a folded position and an open position is attached to the end of a conduit. An introducer capable of moving between a first and second position allows for the expansion of the seal member into an open position. A clamp component is positioned outside of the heart to provide an axial clamping force with the wall of the heart so that a seal is created between the seal member and the wall of the heart.
