Abstract:
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.
