Abstract: The present disclosure provides systems and methods for controlling wireless power transfer systems. A wireless power transfer system includes a transmitter driven by a power source and a transmit controller, wherein the transmitter is configured to control delivery of wireless power, and a receiver inductively coupled to the transmitter, the receiver configured to receive the wireless power from the transmitter and deliver the received wireless power to a load. The receiver includes receiver electronics configured to determine a Thevenin equivalent impedance of the wireless power transfer system, determine a Thevenin equivalent source voltage of the wireless power transfer system, and control, based on the determined Thevenin equivalent impedance and the determined Thevenin equivalent source voltage, an ideal source voltage of the receiver to vary the amount of the wireless power transferred from the transmitter to the receiver.

Abstract: Connectors interfacing a mechanical circulatory system with a patient's natural vasculature are provided herein. Such connectors include aortic connectors that facilitate fluid coupling of an outflow graft tube from an implanted blood pump with a patient's aorta. Aortic connectors can include a substantially planar portion configured for sealed attachment with a wall of the aorta and a tubular connector portion extending from an inlet opening to an outlet opening. The substantially planar portion can include a flexible membrane for attachment to an outer surface of the aorta and/or a flange for engagement with an inner surface of the aorta. The tubular connector can extend from the substantially planar portion at a pre-determined angle and include one or more attachment features to facilitate rapid fluidly sealed attachment to the outflow graft tube.
