    Abstract: A tubular optically-transparent device structured as a terminating cap for an optical fiber is configured to deliver laser radiation from the optical fiber substantially radially (generally—transversely to the axis of the cap) while at the same time spatially-redistributing the radiant intensity at a point of interaction of laser radiation with a wall of the cap to reduce material damage of the material of the cap thereby reducing tissue adhesion during surgery performed with the use of the device including such optical fiber and cap. A method for operating the same.

    Abstract: Optical fibers for delivering laser energy inside the body are often tasked with traversing tortuous routes in accessing the target tissue or pathology, e.g. ureteroscopic laser lithotripsy. A common failure in such applications, known in the field as ‘fiber burn through’, has been known to injure patients and is a major cause of damage to ureteroscopes. Where irregular output that is produced at the start of a lasing interval passes through a fiber that is at or near the optical minimum bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection. The invention disclosed provides a solution to premature fiber failure and collateral damage.

    Abstract: Articles of manufacture, including terminations of or attachments to optical fibers are configured to substantially prevent axial emission and redirect radially most if not all light emanating from optical fibers. In that, a termination may include a fiber cap of a unitary construction of a tube and an optical element disposed to face a sealed end of the tube and dividing a hollow of the tube and having a conical surface, or an optical element dividing the hollow and complemented by a cone. An example of termination includes an optical fiber element having an up-tapered end with a maximum taper-diameter exceeding the core-diameter and ending at a conical element with an apex angle from about 70° to about 100°. Articles of manufacture additionally including mounting contraptions cooperating such terminations with cannulae to form an attachment to a laser system. Methods for transmitting light through such articles of manufacture.

    Abstract: An article of manufacture including a fiber optic termination of a small core optical fiber for use with a surgical laser apparatus (the output from which may be characterized by a high M2 factor) or other high-power or high-energy laser (including an appropriate fiber laser) is configured for safe and efficient coupling of light at a large laser focal point and/or to enable the process of coupling of radiant intensities exceeding the silica fiber damage thresholds and/or those ionizing the air if fully focused therein. The termination may include a glass cylinder structured to include a core region and a glass cladding region the ratio of dimensions of which is substantially equal to the ratio of respectively-corresponding dimensions of the employed optical fiber. A method of propagating light through such article of manufacture.

    Abstract: An all-optical-fiber device configured to supply, to a target, laser radiation having characteristics sufficient for ablating a biological tissue in a manner that is consistent and competitive with the tissue removal geometry and volume provided by conventional electrocautery resection devices. The desired effect is achieved by configuring a facet of the optical fiber or an internal surface of the fiber's termination cap as a surface providing total-internal-reflection of light substantially at every point of such surface while having normals drawn to immediately adjoining surface portions be not parallel with respect to one another.

    Abstract: Optical fibers used to deliver laser energy inside the body are often twisted and bent when passed through tortuous routes in accessing the target tissue or pathology, e.g. during the ureteroscopic laser lithotripsy. When an irregular laser output that is produced at the start of the lasing process is channeled through a fiber that is bent at or near the bend limit, fail safe polymer claddings are damaged and can no longer contain even regular laser output in tight deflection. A common resulting fiber failure, known as ‘fiber burn through’, results in injuries to patients and is a major cause of damage to ureteroscopes. Discussed are the systems and methodologies providing a solution to such premature fiber failure.
