    摘要： Partitioning devices that may be secured and sealed within a heart chamber for separating a patient's heart chamber into a productive portion and a non-productive portion are described herein. The partitioning devices described herein may include a reinforced membrane with outwardly biased members. The reinforced membrane may have 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. These devices may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating an inflatable element on the periphery of the device. The non-productive portion may be filled with a material, including occlusive materials. Sealing and/or filling the non-productive portion formed by the devices described herein may help prevent leakage from the non-productive region. Also described herein are systems including these devices and methods of using them, which may be suitable for treating patients with heart disease, particularly congestive heart failure.

    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.
