ULTRASONIC DEVICE AND METHOD FOR TREATING STONES WITHIN THE BODY

摘要

A system and method to be used in ultrasonic lithotripsy of a stone in a ureter, the system including a catheter having a probe tip capable of transmitting and receiving ultrasonic energy. The catheter can include an inflatable balloon adjacent to the probe tip, the balloon capable of pooling some urine in the ureter to be used as an ultrasonic transmission media. The ultrasonic probe is connected to a source of energy capable of driving the probe tip to deliver ultrasonic energy of a high frequency and relatively low energy to image a stone. Then the probe can be connected to a source of energy capable of driving the probe to deliver a low frequency, high energy ultrasonic to disintegrate the stone.
