Abstract
A catheter for treating calcified plaque includes a catheter body and an expandable balloon. A treatment device of the catheter disrupts and/or modifies the calcified plaque. The treatment device may be a thermal shock generator, a nuclear magnetic resonance generator, or a vibration generator.

1-15. (canceled)
A catheter for treating calcified plaque within a body of a subject, the catheter comprising:
- a catheter body having opposite proximal and distal end portions and a longitudinal axis extending therebetween, wherein the catheter body is configured to be percutaneously inserted into the body of the subject and delivered to a treatment site having calcified plaque;
- an expandable balloon coupled to the distal end portion of the catheter body, wherein the expandable balloon is configured to contact the calcified plaque and apply a radial pressure thereto;
- and
- a thermal shock generator operatively coupled to the expandable balloon and configured to alternate between heating and cooling the calcified plaque to induce thermal shock in the calcified plaque.
A catheter for treating calcified plaque within a body of a subject, the catheter comprising:
- a catheter body having opposite proximal and distal end portions and a longitudinal axis extending therebetween, wherein the catheter body is configured to be percutaneously inserted into the body of the subject and delivered to a treatment site having calcified plaque;
- and
- a nuclear magnetic resonance generator including a radiofrequency coil coupled to a distal end portion of the catheter body, wherein the nuclear magnetic resonance generator is configured to disrupt the calcified plaque.
A catheter for treating calcified plaque within a body of a subject, the catheter comprising:
- a catheter body having opposite proximal and distal end portions and a longitudinal axis extending therebetween, wherein the catheter body is configured to be percutaneously inserted into the body of the subject and delivered to a treatment site having calcified plaque;
- and
- a vibration generator at the distal end portion of the catheter body, the vibration generator configured to generate radial mechanical vibrations suitable to produce resonance in calcified deposits in the calcified plaque, thereby disrupting the calcified deposits.
