Abstract
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.
