摘要： A cardiac constraint jacket is formed of flexible material defining a volume between an open upper end and a lower end. The jacket is dimensioned for an apex of a patient's heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart. A delivery device is used to place the jacket on the heart. The delivery device includes a plurality of attachment locations. Each of the attachment locations is releasably secured to separate positions surrounding a periphery of the open upper end of the jacket. The delivery device also includes a control arrangement which is selectively movable between an open position and a closed position. The control arrangement is connected to the attachment locations such that the attachment locations are in a compact array urging the open upper end of the jacket into a collapsed configuration when the control member is in the closed position. When the control arrangement is in the open position, the attachment locations are in an open array. The attachment locations urge the open upper end of the jacket into an open configuration sufficient for the heart to be inserted into the jacket volume through the open upper end and for the jacket to be slipped over said heart.

摘要： A device for delivery of a cardiac support device for treating cardiac disease of a heart includes a multistage deployment mechanism and an actuating mechanism for controlling the positions of the deployment mechanism. The deployment mechanism is operable to change between a retracted state and an extended state, and includes a plurality of independent stages, including, in one embodiment, a first stage including a guide structure for location adjacent a portion of the patient's heart when in the extended state. A second stage is movably coupled to the first stage, and is guided by the guide structure between the retracted and extended states. The second stage further releasably engages and supports the cardiac support device and positions the cardiac support device at the desired implantation location, guided by the guide structure of the stage. In some embodiments, the deployment mechanism may include additional stages. The actuating mechanism drives the deployment mechanism between the retracted and extended states, and independently controls the positions of the multiple stages of the deployment mechanism.

摘要： A method for implanting a cardiac support device (CSD) on a patient's heart. An amount of contrast agent sufficient to cause structures on the heart to be visible upon fluoroscopic or other imaging is introduced into the pericardial space surrounding the heart. The heart and contrast agent are imaged to provide a visual indication of the location of the structures of the heart. The CSD is placed on the heart using the visual indications provided by the imaging.

摘要： A method for applying a cardiac support device to a heart of a mammal includes surgically accessing a heart, providing a cardiac support device including a jacket, and positioning the jacket around at least a portion of the heart by applying a pulling force to the jacket. The step of positioning the jacket can include using a tool from a position superior to the heart to pull the jacket onto the heart. One device for placing a cardiac support jacket onto the heart includes first and second tubular walls. The second tubular wall is oriented within the first tubular wall and against an internal surface of the first tubular wall. The second tubular wall includes a plurality of grooves and has an open interior volume to hold the cardiac support jacket. Another device for placing a cardiac support jacket onto the heart includes a tubular wall having a plurality of lumens extending between opposite ends of the tubular wall.

摘要： A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary “jacket” that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material. Preferably, the device includes a first adjustment mechanism configured to adjust a tension of the material covering the right ventricle and a second adjustment mechanism configured to adjust the tension of the material covering the left ventricle such that the tension of the material covering the left ventricle can be different than the tension of the material covering the right ventricle.

摘要： The present disclosure is directed to a cardiac reinforcement device (CRD) and method for the treatment of cardiomyopathy. The CRD provides for reinforcement of the walls of the heart by constraining cardiac expansion, beyond a predetermined limit, during diastolic expansion of the heart. A CRD of the invention can be applied to the epicardium of the heart to locally constrain expansion of the cardiac wall or to circumferentially constrain the cardiac wall during cardiac expansion.
