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.
Claims16
A method of treating a calcified lesion, the method comprising:
- providing a catheter having:
- a hollow sheath defining a lumen;
- a dilating balloon sealed to the hollow sheath and defining an annular channel around an exterior of the hollow sheath;
- and
- a shock wave generator located within the annular channel defined by the balloon and adjacent to the exterior of the hollow sheath;
- guiding the catheter along a guidewire received in the lumen until the balloon is adjacent the calcified lesion;
- inflating the balloon with a fluid;
- providing energy to the shock wave generator from a power source;
- and
- generating a shock wave from the shock wave generator, wherein the shock wave exerts a peak pressure of 1000 psi.
