    Abstract: The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an energy receiving component for receiving energy from an energy source positioned external to the body, an energy storage component for storing the received energy, and/or a flow control mechanism for adjusting a geometry of the lumen.

    Abstract: A wireless power transfer system is provided. The system includes an external transmit resonator and an implantable receive resonator. The transmit resonator is configured to transmit wireless power, wherein the external transmit resonator includes one of i) one or more loops of Litz wire and ii) a plurality of stacked plates. The implantable receive resonator is configured to receive the transmitted wireless power from the external transmit resonator, wherein the implantable receive resonator is configured to power a ventricular assist device (VAD) implanted in a subject using the received wireless power. The implantable receive resonator includes the other of i) the one or more loops of Litz wire and ii) the plurality of stacked plates.

    Abstract: A hemodynamic flow assist device includes a miniature pump, a basket-like cage enclosing and supporting the pump, and a motor to drive the pump. The device is implanted and retrieved in a minimally invasive manner via percutaneous access to a patient's artery. The device has a first, collapsed configuration to assist in implantation and a second, expanded configuration once deployed and active. The device is deployed within a patient's aorta and is secured in place via a self-expanding cage which engages the inner wall of the aorta. The device includes a helical screw pump with self-expanding blades, sensors, and anchoring structures. Also disclosed is a retrieval device to remove the hemodynamic flow assist device once it is no longer needed by the patient and an arterial closure device to close the artery access point after implantation and removal of the hemodynamic flow assist device. The hemodynamic flow assist device helps to increase blood flow in patients suffering from congestive heart failure and awaiting heart transplant.
