Abstract
A catheter that fits within a blood vessel wall includes electrodes aligned along a longitudinal axis of the catheter that produce unfocused shock waves that propagate radially toward the blood vessel wall for treatment.
Claims24
An apparatus comprising:
- a catheter sized to fit within a wall of a blood vessel, wherein the catheter includes a distal end inserted into the blood vessel;
- a balloon including a liquid inlet coupled to the catheter;
- first and second electrodes coupled to the catheter within the balloon and aligned on a longitudinal axis along the length of the catheter, wherein the electrodes upon electrical discharge produce an unfocused radial pressure shock wave that propagates away from the longitudinal axis, and wherein one or both of the first and second electrodes do not intersect outward propagation of the unfocused radial pressure shock wave in a direction from the longitudinal axis of the catheter to the wall of the blood vessel;
- a first radiopaque marker coupled to the catheter at a proximal end of the balloon and a second radiopaque marker coupled to the catheter at an opposite distal end of the balloon;
- and
- the first and second electrodes positioned within the balloon between the first radiopaque marker and the second radiopaque marker.

An apparatus comprising:
- a catheter sized to fit within a blood vessel, wherein the catheter includes a distal end tip inserted into the blood vessel;
- first and second electrodes within a balloon coupled to the catheter, wherein the balloon includes liquid, and wherein the electrodes are aligned to generate a shock wave that propagates perpendicular to a longitudinal axis along the length of the catheter, and wherein the electrodes are configured to electrically produce an unfocused radial pressure shock wave in the liquid of the balloon, and wherein the unfocused radial pressure shock wave propagates away from the longitudinal axis of the catheter to a wall of the blood vessel free of intersection by one or both of the first and second electrodes;
- a first radiopaque band coupled to the catheter that visually indicates a proximal end of the balloon and a second radiopaque band coupled to the catheter that visually indicates an opposite distal end of the balloon;
- and
- the first and second electrodes positioned within the balloon between the first and second radiopaque bands.
