Abstract
The present disclosure provides medical optical fibers configured to couple to medical laser systems and convey laser energy to a target. The medical optical fibers comprise a fiber core surrounded by a cladding which is further surrounded by a jacket. The overall diameter of the jacket is configured for use with conventional endoscopes, but the diameter of the fiber core is configured to convey the laser energy at power densities to cause interactions between the laser energy and the target and between the laser energy and the liquid medium in which the target is found.

A medical optical fiber, comprising:
- a proximal connector, a distal tip, and an elongate shaft extending between the proximal connector and the distal tip,
- the elongate shaft comprising:
- a fiber core;
- a cladding surrounding the fiber core;
- and
- a jacket surrounding the cladding,
- wherein a ratio of the diameter of the fiber core over the diameter of the elongate shaft is less than or equal to 0.75.
A medical laser system, comprising:
- a laser console comprising a laser source and a controller, the controller configured to identify laser pulse parameters and to cause the laser source to generate laser energy having the laser pulse parameters;
- and
- a medical optical fiber, comprising:
- a proximal connector, a distal tip, and an elongate shaft extending between the proximal connector and the distal tip,
- the elongate shaft comprising:
- a fiber core;
- a cladding surrounding the fiber core;
- and
- a jacket surrounding the cladding,
- wherein a ratio of the diameter of the fiber core over the diameter of the elongate shaft is less than or equal to 0.75.
A medical optical fiber, comprising:
- a proximal connector, a distal tip, and an elongate shaft extending between the proximal connector and the distal tip,
