Implantable shunt systems and methods

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.
