Abstract
An apparatus includes a balloon adapted to be placed adjacent a calcified region of a body. The balloon is inflatable with a liquid. The apparatus further includes a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon. The shock wave generator includes a plurality of shock wave sources distributed within the balloon.
Claims45
An apparatus, comprising:
- a balloon adapted to be placed adjacent a calcified region of a body, the balloon being inflatable with a liquid;
- and
- a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon,
- wherein the shock wave generator comprises a plurality of shock wave sources distributed within the balloon, wherein the plurality of shock wave sources comprises more than two shock wave sources.
1 more element
An apparatus, comprising:
- an elongated carrier;
- a balloon carried on the elongated carrier in sealed relation thereto, being adapted to be placed adjacent a calcified region of a body, and being inflatable with a liquid;
- and
- an electrical arc shock wave generator within the balloon, the electrical arc shock wave generator comprising more than two electrodes distributed within the balloon, each electrode adapted to produce shock waves that propagate through the liquid for impinging upon the calcified region adjacent the balloon, and a counter electrode adapted to be in contact with the liquid and to receive a voltage polarity opposite that applied to the more than two electrodes.
1 more element
A method comprising:
- inserting a balloon in a body adjacent a calcified region;
- inflating the balloon with a liquid to cause the balloon to contact the calcified region;
- placing, within the balloon, a shock wave generator including more than two shock wave sources and distributing the more than two shock wave sources within the balloon;
- and
- causing the shock wave sources to form shock waves that propagate through the liquid and impinge upon the calcified region.
2 more elements
A method comprising:
- inserting a balloon in a body adjacent a calcified region;
- inflating the balloon with a liquid to cause the balloon to contact the calcified region;
- placing within the balloon more than two electrodes in non-touching relation to the balloon and adjacent the calcified regions;
- placing a counter electrode in contact with the liquid;
- and
- applying voltage pulses between the more than two electrodes and the counter electrode, the voltage pulses having a first polarity applied to the two or more electrodes and a second polarity applied to the counter electrode causing the more than two electrodes to form shock waves that propagate through the liquid and impinge upon the calcified region.
