Abstract
A device for ultrasound assisted thrombolysis includes a catheter, a first ultrasound module, a second ultrasound module and a controller. The first and second ultrasound modules are mounted in the catheter and electrically connected to the controller. The first ultrasound module is provided to transmit ultrasonic waves toward a thrombus to assist thrombolysis. The second ultrasound module is provided to transmit ultrasonic waves toward the thrombus for measuring a distance between the catheter and the thrombus. The controller is provided to control the first and second ultrasound modules according to the distance.
Claims16
A device for ultrasound assisted thrombolysis comprising:
- a catheter including a wall and an accommodation space which is surrounded by the wall;
- at least one first ultrasound module mounted in the accommodation space and configured to transmit a first ultrasonic wave, the first ultrasonic wave is configured to dissolve a thrombus located outside the catheter;
- at least one second ultrasound module mounted in the accommodation space and configured to transmit a second ultrasonic wave, the second ultrasonic wave is configured to act on the thrombus and allow a third ultrasonic wave to be reflected from the thrombus, wherein a frequency of the second ultrasonic wave is greater than a frequency of the first ultrasonic wave;
- and
- a controller electrically connected to the at least one first ultrasound module and the at least one second ultrasound module, the controller is configured to measure a distance between the catheter and the thrombus according to a time difference between transmitting the second ultrasonic wave and receiving the third ultrasonic wave, and the controller is configured to switch on continuously or switch off the at least one first ultrasound module and the at least one second ultrasound module according to the distance between the catheter and the thrombus.
