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.

摘要: An apparatus for placing a cardiac support device (CSD) on a heart. The apparatus includes a body, a deployment mechanism on the body for supporting the CSD in an open position for placement on the heart, and a release mechanism coupled to the deployment mechanism for releasably mounting the CSD to the deployment mechanism. The release mechanism includes a release element for releasably engaging the CSD, and a release actuator coupled to the release element for actuating the release element to release the CSD.

摘要: A device for treating cardiac disease of a heart having an upper portion and a lower portion divided by an A-V groove, the device including a jacket adapted to be secured to the heart, and a non-adherent material in association with the jacket. The jacket is fabricated from a flexible material defining a volume between an upper and a lower end, the jacket being adapted to be adjusted on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain expansion of the heart beyond the maximum adjusted volume during diastole and permit substantially unimpeded contraction of the heart during systole. As a result of the flexible material, the jacket allows unimpeded diastolic filling of the heart. Also described is a method for treating cardiac disease including surgically accessing the heart, applying the treatment device of the invention, securing the treatment device to the heart, and surgically closing access to the heart while leaving the treatment device on the heart.

摘要: Tools for managing the pericardium during intra-pericardial procedures such as the delivery of cardiac support devices. One embodiment of the tool includes a tubular body of low friction material having a diameter, a fixed lip on an exterior end and an extendable lip on an interior end. The extendable lip moves with respect to the body between a retracted state and an expanded state. The tool is inserted through an incision in the pericardium and deployed by moving the lip to the expanded state. When deployed a barrier portion of the body engages the edges of the incision and the extendable lip lines the inside of the pericardium around the incision.

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.
