Abstract
Described here are devices and methods for forming shock waves. The devices may comprise an axially extending elongate member. A first electrode pair may comprise a first electrode and a second electrode. The first electrode pair may be provided on the elongate member and positioned within a conductive fluid. A controller may be coupled to the first electrode pair. The controller may be configured to deliver a series of individual pulses to the first electrode pair, where each pulse creates a shock wave. The controller may cause current to flow through the electrode pair in a first direction for some of the pulses in the series and in a second direction opposite the first direction for the remaining pulses in the series.
