A curved laser probe with single-use optic fiber may include a reusable handle, an optic fiber fixture, and a single-use optic fiber. The single-use optic fiber may include an optic fiber having an optic fiber distal end and an optic fiber proximal end. The optic fiber may be disposed in a first transitory connector having a first transitory connector distal end and a first transitory connector proximal end wherein the optic fiber distal end extends a fixed distance from the transitory connector distal end. The optic fiber may be disposed in a second transitory connector having a second transitory connector distal end and a second transitory connector proximal end wherein the optic fiber proximal end extends a fixed distance from the second transitory connector distal end. The first transitory connector may be inserted in the reusable handle and the second transitory connector may be inserted in the optic fiber fixture.

A side-fire laser fiber includes an optical fiber having a distal end and a fiber cap. The fiber cap is coupled to the distal end of the optical fiber and includes a molded reflective surface and a sealed cavity. The molded reflective surface defines a wall of the cavity. Laser energy discharged from the distal end along a central axis of the optical fiber is reflected off the molded reflective surface in a direction that is transverse to the central axis.

A waveguide for high efficiency transmission of high energy light useful in ablation procedures at predetermined bandwidths over predetermined distances comprising: an optical fiber core; a silanization agent; layered cladding surrounding the optical fiber core comprising: a first thin metal layer comprising at least two types of metals the first thin metal layer covalently bonded to the core and a second thin metal layer bonded to the second metal layer, and a catalyst component; wherein the silanization agent comprising organofunctional alkoxysilane molecule, such as 3-aminopropyltriethoxysilane (APTS), is a self supporting bridge between the surface of the optical fiber and the first metal layer; the first metal layer is uniformly chemisorbed onto the surface of the optical fiber by means of covalent SiOSi bonds with the optical fiber; further wherein the catalyst component derived from an activation solution for enhancing the layered cladding upon the optical fiber.

In one aspect of the present disclosure, a laser fiber may include an optical fiber. The optical fiber may include a proximal portion. The optical fiber also may include a distal portion having a distal end. The optical fiber may be configured to transmit laser energy from the proximal portion to the distal portion for emission of the laser energy from the distal end. The optical fiber also may include a distal tip surrounding the distal portion to protect the distal portion. The distal tip may include a sheet glass material having a laser energy emitting surface. The laser energy emitting surface may be defined by a chemically-strengthened surface layer.

Embodiments of the invention include a method of initiating an optical fiber. In some embodiments, a distal portion of the optical fiber is coated with an energy absorbing material. In some embodiments, the material includes a metal flakes or powder dispersed in a solution of organic solvents. After the material dries, laser energy is fired through the optical fiber. The laser energy can be absorbed in the material and ignites the organic solvents. This combustion melts the material of the optical fiber, and impregnates the optical fiber with the metal flakes or powder of the material. The resulting optical fiber is thus permanently modified so that the energy applied through the fiber is partially absorbed and converted to heat.

The Integrated Laser Basket (ILB)a medical device used for treating various types of stone deposits, including, but not limited to, kidney stones, gallstones, bladder stones, prostate stones, pancreatic stones, or any combination thereof, in human or animal patients. The ILB merges the benefits of laser lithotripsy and stone retrieval in a single device, offering a more comprehensive and minimally invasive approach to stone management. Example methods of using the ILB to treat various types of stone deposits in human and non-human patients are also described.
