Abstract
The present technology is directed to adjustable interatrial shunting systems that selectively control blood flow between the left atrium and the right atrium of a patient. The adjustable interatrial devices include a shunting element having an outer surface configured to engage native tissue and an inner surface defining a lumen that enables blood to flow from the left atrium to the right atrium when the system is deployed across the septal wall. The systems can include an actuation assembly for selectively adjusting a geometry of the lumen and/or a geometry of a lumen orifice to control the flow of blood through the lumen.
