First Claim
Patent Images
1. A catheter comprising:
- an elongated carrier;
a balloon at one end of the carrier in sealed relation thereto,the carrier including a channel arranged to receive a fluid therein that inflates the balloon to an internal pressure of greater than two atmospheres; and
an arc generator within the balloon that forms a mechanical shock wave within the balloon.

Abstract
A system and method for breaking obstructions in body lumens includes a catheter including an elongated carrier, a balloon at one end of the carrier in sealed relation thereto, the carrier including a channel arranged to receive a fluid that fills and pressurizes the balloon to an internal pressure of greater than two atmospheres, 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.

9. A method comprising:
-
providing a catheter including an elongated carrier, a balloon at one end of the carrier in sealed relation thereto, the carrier including a channel 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; inserting the catheter into a body lumen of a patient adjacent to an obstruction of the body lumen; admitting fluid into the carrier channel to inflate the balloon to an internal pressure above two atmospheres; and
applying high voltage pulses to the arc generator to form a series of mechanical shocks within the balloon. - View Dependent Claims (10)
