摘要： A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.

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 method for efficiently implanting a cardiac support device on a patient's heart. The method includes causing lubricious material to be located between the cardiac support device and the heart while the cardiac support device is being implanted on the heart. The lubricious material is removed from between the cardiac support device and the heart after the cardiac support device is implanted.

摘要： A delivery device for efficiently delivering a cardiac support device of the type having a jacket. The device includes a body, a deployment mechanism and an actuating mechanism. The deployment mechanism is for releasable connection to a cardiac support device and movable within the jacket between retracted and extended states to drive the jacket between collapsed and open configurations. At least portions of the deployment mechanism within the jacket have a lubricious surface to substantially reduce friction between the jacket and a heart onto which the jacket is being positioned. The actuating mechanism moves the deployment mechanism between the retracted and extended states.

摘要： A method for managing the pericardium during intra-pericardial procedures such as the delivery of cardiac support devices. One embodiment of the method includes making an incision through the pericardium to provide access to the pericardial space, and inserting a plurality of strips of lubricious material into and through the incision. The strips of material are spaced around the edges of the incision to form a tubular barrier against the pericardium. End portions of the strips of material in the pericardial space are expanded away from the body to form a lip that lines the inside of the pericardium around the incision.

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.
