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.

摘要： A system for improving cardiac function is provided. A foldable and expandable frame having at least one anchoring formation is attached to an elongate manipulator and placed in a catheter tube while folded. The tube is inserted into a left ventricle of a heart where the frame is ejected from the tube and expands in the left ventricle. Movements of the elongate manipulator cause the anchor to penetrate the heart muscle and the elongate manipulator to release the frame. The installed frame minimizes the effects of an akinetic portion of the heart forming an aneurysmic bulge. Devices and methods are described herein which are directed to the treatment of a patient's heart having, or one which is susceptible to heart failure, to improve diastolic function.

摘要： Systems for partitioning a ventricle of a heart include a partitioning device or implant, and an applicator for inserting, repositioning and/or removing the partitioning device. The implant may support the ventricle wall and may reduce the volume of the ventricle. The delivery system for delivering and deploying a partitioning device into a ventricle may include a catheter having a distal coupling element for coupling to a partitioning device in a collapsed configuration; the catheter may also have an expansion member for applying force to the partitioning device to fully expand it into a deployed configuration and to secure or seal it against the ventricle wall.

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.
