    Abstract: A method is disclosed for treating calcified lesions within a wall of a blood vessel. The first step includes breaking apart a calcified lesion using a plurality of shockwaves generated in an angioplasty balloon of an angioplasty catheter device. The angioplasty balloon is dilated via a fluid to a first extent to fit against at least a portion of the wall of the blood vessel. A plurality of electrical pulses are delivered to a pair of electrodes disposed within the fluid inside the balloon. The electrical pulses have an amplitude sufficient to create plasma arcs in the fluid to generate shockwaves that are conducted through the fluid and through the balloon to the blood vessel, to crack the calcified lesion. After breaking apart the calcified lesion, the angioplasty balloon is allowed to further expand to a second extent greater than the first extent, thereby expanding an opening in the blood vessel.

    Abstract: Described herein are shock wave devices and methods for the treatment of vascular plaques. One variation of a shock wave device may include a pair of elongated, flexible concentric tubes comprising an inner tube and an outer tube. The inner tube and the outer tube may be connected together at one end, and at least a portion of the volume between the inner tube and the outer tube may be filled with a conductive fluid via the other end. At least two electrodes may be positioned between the inner tube and the outer tube, the at least two electrodes being electrically connectable to a voltage source and configured to generate shock waves in the conductive fluid in response to voltage pulses.

    Abstract: A system for breaking obstructions in body lumens includes a catheter including an elongated carrier, a balloon about the carrier in sealed relation thereto, the balloon being arranged to receive a fluid therein that inflates the balloon, and an arc generator including at least one electrode within the balloon that forms a mechanical shock wave within the balloon. The system further includes a power source that provides electrical energy to the arc generator.

    Abstract: A catheter comprises an elongated carrier and a balloon carried by the carrier in sealed relation thereto. The balloon has an outer surface and is arranged to receive a fluid therein that inflates the balloon. The catheter further comprises a shock wave generator within the balloon that forms mechanical shock waves within the balloon, and a medicinal agent carried on the outer surface of the balloon. The medicinal agent is releasable from the balloon either before or in response to the shock wave.
