an embolism detector securable to a patient with a detection field including a detection area in the blood vessel, the embolism detector operable for transmitting data indicating the presence of an embolism in the detection area;
an implantable container disposed within the lumen defined by the support stent, to be in fluid communication with the blood vessel at least part of the time;
a diverter controller operatively coupled to the embolism detector, the diverter controller operable for receiving data from the embolism detector indicating the presence of the embolism in the detection area; and
an ultrasound emitter securable to the patient, the ultrasound emitter coupled to the diverter controller and operable thereby to activate the ultrasound emitter to direct ultrasound toward a target area in response to the presence of the embolism in the detection field, the ultrasound sufficient to steer a substantial fraction of emboli into the implantable container, wherein the implantable container includes a fill level detector configured to indicate a fill level of the implantable container; and
machine readable instructions that when executed on the diverter controller, activate the ultrasound emitter based on a target input receivable by the diverter controller.
