Abstract: Systems and related methods for supplying power to a medical device employ serially-connectable portable batteries. A method of supplying electrical power to a medical device includes discharging a first external battery to output electrical power to a second external battery. Distribution of the electrical power received by the second external battery is controlled to simultaneously charge the second external battery and output electrical power from the second external battery to supply electrical power to the medical device.

Abstract: Systems, methods, and devices for improved cooling of an implantable blood pump employ a thermal conductor to conduct heat to blood flowing through the blood pump. A method includes drawing a flow of blood into a blood pump, passing the flow of blood through the blood pump such that heat flow is conducted to the flow of blood via the thermal conductor, and outputting the flow of blood from the blood pump.
