SYSTEMS, METHODS, AND CATHETERS FOR ENDOVASCULAR TREATMENT OF A BLOOD VESSEL

In one aspect, a system for endovascular treatment of a blood vessel includes a control unit, an ultrasound device, an actuator, and a catheter having a treatment portion. The ultrasound device is communicatively coupled to the control unit. The ultrasound device includes an ultrasound probe having a subject contact surface. The actuator is coupled to the ultrasound probe and is operable to move the subject contact surface of the ultrasound prove relative to a treatment zone of a subject. The control unit is configured to determine a position of the treatment portion of the catheter as the catheter is advanced through the blood vessel, and move the subject contact surface of the ultrasound probe relative to the treatment zone of the subject with the actuator to follow the position of the catheter as the catheter is advanced through the blood vessel. 在一方面，一种用于血管的血管腔内治疗的系统包括控制单元、超声设备、致动器和具有治疗部分的导管。超声设备通信地联接到控制单元。超声设备包括具有受试者接触表面的超声探头。致动器联接到超声探头并且可操作以相对于受试者的治疗区移动超声探头的受试者接触表面。控制单元被配置为在导管被推进通过血管的过程中确定导管的治疗部分的位置，并在导
