Abstract

Claims (17)

1. An apparatus comprising:

a blood vessel catheter including a distal end insertable into a blood vessel and a proximal end opposite the distal end;

a first electrode paired with a second electrode within a non-perforated balloon coupled to and inflatable around the catheter between the distal end and the proximal end, wherein the distal end of the catheter extends beyond a sealed end of the balloon, and wherein the balloon includes a liquid inlet;

the first electrode and second electrode aligned to not extend beyond the distal end of the catheter; and

a first radiopaque marker coupled to the catheter that visually indicates a first end of the balloon nearer the proximal end of the catheter and a second radiopaque marker coupled to the catheter that visually indicates a second distal end of the catheter nearer the distal end of the catheter; and

the first and second electrodes positioned within the balloon between the first and second radiopaque markers.

2. The apparatus of claim 1 , further comprising an electronic controller connection to at least one of the first and second electrodes.

3. A method of treating a target area of a blood vessel wall with the apparatus of claim 1 , further comprising providing liquid into the balloon after aligning the catheter and first electrode and second electrode at a desired position relative to the target area with guidance by the first radiopaque marker and the second radiopaque marker and removing liquid from the balloon after delivering shock wave treatment.

4. The apparatus of claim 1 , wherein the first electrode and second electrode are configured to produce non-focused shock waves.

5. An apparatus comprising:

a catheter sized to fit within a blood vessel, wherein the catheter includes a distal end that is insertable into a blood vessel and a proximal end opposite the distal end;

a non-perforated balloon coupled to and inflatable around the catheter between the distal end and the proximal end, wherein the distal end of the catheter extends beyond a sealed end of the balloon;

a liquid inlet in the balloon;

a plurality of shock wave generators coupled to the catheter within the balloon, wherein the shock wave generators upon electrical discharge produce shock waves that propagate away from the length of the catheter;

one or more radiopaque markers coupled to the catheter to identify the location of the balloon; and

an electronic controller connection to the shock wave generators, wherein the plurality of shock wave generators is configured to produce non-focused shock waves.

6. The apparatus of claim 2 , wherein the first electrode and second electrode are configured to produce non-focused shock waves.
