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.

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 membrane with a plurality of inflatable elements. The membrane may include a valve disposed in a central region of the membrane with a plurality of inflation channels extending radially from the valve. These devices may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating the plurality of inflatable elements 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.
