Claim 12:
13. A shockwave transducer comprising:
two similarly shaped and parallel flat coils of wire separated by a restoring insulator, said coils being in electrical communication with a current source, wherein said current source has an operative configuration to deliver current pulses of same polarity to said coils so as to produce pulses of pulling forces that pull said coils towards each other, said pulling forces producing rarefaction shockwaves, and
wherein said insulator comprises a planar sheet having first and second planar surfaces and first and second edges at opposite ends of said first and second planar surfaces, and wherein one portion of said wire lies across said first planar surface, wraps around said first edge and then lies across said second planar surface, and then wraps around said second edge and then again lies across said first planar surface at a distance apart from where it previously lied across said first planar surface, and then again wraps around said first edge and then again lies across said second planar surface at a distance apart from where it previously lied across said second planar surface, and then again wraps around said second edge and then again lies across said first planar surface at a distance apart from where it previously lied across said first planar surface.
