An actuation system for assisting the operation of the natural heart includes an actuator element adapted to be positioned proximate a portion of a heart wall. The actuator element is operable for acting on the heart wall portion to effect a change in the shape of the heart. A shape-limiting element is configured for being positioned proximate a heart wall. The shape-limiting element is operable for flexing to assume a curvature no greater than a predetermined curvature when the heart wall is acted upon and maintaining that predetermined curvature to control the shape of the actuated heart.

A system for studying a beating explanted heart comprises a fluid inflow circuit configured for coupling to an explanted heart to direct fluid for flowing into a ventricle of the heart, and a fluid outflow circuit configured for coupling to an explanted heart to direct fluid flowing out of the ventricle of the beating heart. A flow meter coupled with the inflow circuit measures the inflow rate of fluid into the heart ventricle and a flow meter coupled with the outflow circuit measures the outflow rate of fluid out of the heart ventricle. A processing system converts the inflow and outflow rates into incremental volume changes in the volume of the heart ventricle and adds and subtracts the incremental volume changes from a relative volume of the heart ventricle to study volume changes in the explanted heart while it is beating.
