Abstract
A method includes the step of inserting a catheter inside a vein adjacent to an artery and inflating a balloon within the vein. A focus of a reflector for a shockwave emitter on the catheter is adjusted to be within the artery. The method further includes generating a shockwave within the balloon and directing the shockwave via the reflector through the wall of the vein and the wall of the artery.

A method for fracturing a calcified occlusion from a vein adjacent to an artery containing the calcified occlusion, the method comprising:
- inserting a catheter with an energy emitter into the vein;
- actuating the energy emitter to generate a shockwave within the vein;
- and
- directing the shockwave through a wall of the vein and through a wall of the artery to deposit energy in the artery and fragment the calcified occlusion.
A method of treating calcified plaque in an artery, the method comprising:
- advancing a catheter through a vein and positioning a shockwave emitting portion of the catheter in the vein adjacent a calcified region of an artery, generating a shockwave within the vein by a shockwave emitter at the shockwave emitting portion of the catheter;
- directing at least a portion of the shockwave towards the calcified region of the artery, and
- breaking at least a portion of the calcified plaque in the calcified region of the artery.
A method comprising:
- advancing a distal region of a catheter through a vein to a region of the vein proximate a calcified region of an artery;
- generating a shockwave within the vein using the distal region;
- directing at least a portion of the shockwave from the vein towards the calcified region of the artery, and
- breaking at least a portion of the calcified region with the shockwave.
