Apparatus and methods are described for regulating blood flow in an ascending aorta of a subject including inserting a device into the ascending aorta. When in a deployed state, the device defines an inner surface that defines a conduit through the device, at least a portion of the inner surface diverging, such that a cross-sectional area of the conduit at the downstream end of the diverging portion is greater than a cross-sectional area of the conduit at the upstream end of the diverging portion. The device is deployed within a longitudinal portion of the ascending aorta, such that the device defines the conduit throughout deployment of the device within the longitudinal portion of the ascending aorta. Other applications are also described.
