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.
Claims6
An apparatus comprising:
- a catheter sized to fit within a wall of a blood vessel;
- a balloon including a liquid inlet coupled to the catheter, wherein the catheter includes a distal end closed tip that is distal to the balloon, and
- first and second electrodes within the balloon aligned on a longitudinal axis along the length of the catheter, wherein the electrodes upon electrical discharge produce unfocused radial pressure shock waves in liquid of the balloon, and wherein one or both of the first and second electrodes do not intersect outward propagation of the unfocused radial pressure shock waves in a direction from the longitudinal axis of the catheter to the wall of the blood vessel.
An apparatus comprising:
- a catheter sized to fit within a blood vessel wall;
- first and second electrodes within a balloon coupled to the catheter, wherein the balloon includes liquid, wherein the catheter includes a distal end closed tip that is distal to the balloon and the distal end closed tip includes radiopaque material;
- and
- the electrodes aligned on a longitudinal axis along the length of the catheter, wherein the electrodes are configured to electrically produce unfocused radial pressure shock waves in the liquid of the balloon, and wherein the unfocused radial pressure shock waves propagate from the longitudinal axis of the catheter to the blood vessel wall free of intersection by one or both of the first and second electrodes, wherein the electrodes are positioned to generate the shock waves from discharge within the inner construction of the catheter.
