Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps. 本申请描述了一种用于处理脉管闭塞物的冲击波装置。该冲击波装置包括外覆盖层和在装置的远端处连接的内部构件。第一和第二导丝在外覆盖层与所述内部构件之间的容积内沿着装置的长度延伸。导电发射带围绕第一和第二丝的端部，以形成第一导丝的端部与发射带之间的第一火花隙和第二导丝的端部与发射带之间的第二火花隙。当该容积充填有导电流体并且在第一和第二丝两端施加高电压脉冲时，可以从第一和第二火花隙引发第一和第二冲击波。
