Abstract: Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.

Abstract: A laser system may include a laser resonator configured to emit an input laser beam having an elliptical cross-sectional shape. The laser system also may include first reflective device configured to reflect the input laser beam to produce a first reflected laser beam. The first reflective device may include a spherical surface for reflecting the input laser beam. The laser system also may include a second reflective device configured to reflect the first reflected laser beam to produce a second reflected laser beam. The laser system also may include a coupling device configured to focus the second reflected laser beam to produce an output laser beam. The coupling device may include a spherical surface for receiving the second reflected laser beam. The laser system also may include an optic fiber configured to transmit the output laser beam for emission of the output laser beam onto a target area.

Abstract: A side-fire laser fiber (102) includes an optical fiber (112) having a distal end (116) and a fiber cap (114). The fiber cap is coupled to the distal end of the optical fiber and includes a molded reflective surface (130) and a sealed cavity (132A or 132B). The molded reflective surface defines a wall of the cavity. Laser energy discharged from the distal end along a central axis (124) of the optical fiber is reflected off the molded reflective surface in a direction that is transverse to the central axis.

Abstract: A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.

Abstract: 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.
