Abstract
A catheter system for treating a treatment site within or adjacent to a vessel wall includes a light source, a balloon, a light guide, and an optical analyzer assembly. The light source generates light energy. The balloon is positionable substantially adjacent to the vascular lesion. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The light guide receives light energy from the light source at a guide proximal end and guides the light energy toward a guide distal end and into the balloon interior. The optical analyzer assembly is configured to optically analyze light energy emitted from the guide proximal end of the light guide.
Claims24
A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve, the catheter system being configured to use a balloon fluid, the catheter system comprising:
- a light source that generates light energy;
- a balloon that is positionable substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior, the balloon interior being configured to receive the balloon fluid;
- a light guide that is configured to receive the light energy from the light source at a guide proximal end and guide the light energy so that the light energy from the light source moves through the light guide in a first direction from the guide proximal end toward a guide distal end that is positioned within the balloon interior, the light energy from the light source that moves through the light guide in the first direction being configured to generate plasma in the balloon fluid within the balloon interior, the guide distal end of the light guide being in fluid communication with the balloon fluid in which the plasma is configured to be generated, the light guide being configured to subsequently guide a portion of the light energy from the light source that is configured to generate the plasma in the balloon fluid within the balloon interior back through the light guide from the guide distal end to the guide proximal end in a second direction that is opposite the first direction, the portion of the light energy that is guided back through the light guide in the second direction being emitted from the plasma that is generated in the balloon fluid within the balloon interior;
- and
- an optical analyzer assembly that is configured to optically analyze the portion of the light energy from the guide proximal end of the light guide that moved back through the light guide in the second direction.
A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve, the catheter system being configured to use a balloon fluid, the catheter system comprising:
- a light source that generates light energy;
- a balloon that is positionable substantially adjacent to the treatment site, the balloon having a balloon wall that defines a balloon interior, the balloon interior being configured to receive the balloon fluid to expand the balloon to an expanded configuration;
- a light guide that is configured to receive the light energy from the light source at a guide proximal end and guide the light energy so that the light energy from the light source moves through the light guide in a first direction from the guide proximal end toward a guide distal end that is positioned within the balloon interior, the light energy from the light source that moves through the light guide in the first direction being configured to generate plasma in the balloon fluid within the balloon interior that has been used to expand the balloon to the expanded configuration, the light guide being configured to subsequently guide a portion of the light energy from the light source that is configured to generate the plasma in the balloon fluid within the balloon interior that has been used to expand the balloon to the expanded configuration back through the light guide from the guide distal end to the guide proximal end in a second direction that is opposite the first direction, the portion of the light energy that is guided back through the light guide in the second direction being emitted from the plasma that is generated in the balloon fluid within the balloon interior;
- and
- an optical analyzer assembly that is configured to optically analyze the portion of the light energy from the guide proximal end of the light guide that moved back through the light guide in the second direction.
