摘要：
A guidewire includes an elongated member and a shaft extending distally from the elongated member, wherein the elongated member and shaft are configured to be navigated through vasculature of a patient. The guidewire further includes a first conductor extending around the shaft to define an outer perimeter of the guidewire and a first electrode adjacent the shaft. The first conductor is configured electrically connect the first electrode to an energy source. The guidewire further includes a second electrode and a second conductor configured to electrically couple the second electrode to the energy source. The first and second electrodes may be configured to deliver an electrical signal to fluid contacting the first and second electrodes to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
