An ultrasonic probe comprising a housing, a first ultrasonic transducer array, a second ultrasonic transducer array, a first light source, and a second light source. The first ultrasonic transducer array is coupled to the housing and configured to emit a first planar ultrasonic beam in a first direction within a first plane. The second ultrasonic transducer array is coupled to the housing and configured to emit a second planar ultrasonic beam in the first direction within a second plane, which is substantially perpendicular to the first plane. The first light source is coupled to the housing and configured to project a first light line substantially within the first plane. The second light source is coupled to the housing and configured to project a second light line within a third plane, which is substantially perpendicular to the first plane and intersects the second plane at an oblique angle. The first light line intersects and is substantially perpendicular to the second light line.

A noninvasive treatment of uterine growths such as myomas (fibroids) and polyps is presented. Treatment involves carrying out diagnostic hysteroscopy and ultrasound procedures to detect, measure, and evaluate unwanted uterine growths; then inserting optical fiber into a hysteroscope, reaching target tissue with optical fiber and eliminating said tissue or shrinking it to a size/shape for easy mechanical removal. Finally, ultrasound imaging is used to confirm success of procedure. In one embodiment, optical fiber has an off-axis firing end but can be inserted inside a conventional hysteroscopy device. In another embodiment, a laser interstitial thermal therapy (LITT) fiber is used to treat myomas found on the outside of the uterus. A high energy laser is used that can emit at wavelengths easily absorbed by water and blood, such as 980 nm and 1470 nm. Procedure is fast and can be done in the physician's office with little or no anesthesia used.

A system for working biological tissue, the system comprising: a tool comprising a laser operable to perform at least one action of work; positioning means for positioning the tool relative to the biological tissue to perform the at least one action of work; a controller; storage storing electronic program instructions for controlling the controller; and an input means; wherein the controller is operable, under control of the electronic program instructions, to: receive input via the input means; process the input and, on the basis of the processing, control the positioning means and the tool to work the biological tissue.

Certain aspects of the present disclosure provide a thermally robust laser probe assembly comprising a cannula, wherein one or more optical fibers extend at least partially through the cannula for transmitting laser light from a laser source to a target location. The probe assembly further comprises a lens housed in the cannula and a protective component press-fitted to the distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.

Systems and methods for creating multi-spot laser light beams, multiplexing an illumination light and the multi-spot laser light beams, delivering the multiplexed light to a surgical handpiece via a multi-core optical fiber cable, and delivering the multiplexed light onto patient anatomy.

Certain embodiments of the present disclosure provide a thermally robust laser probe assembly. The probe assembly comprises a cannula through which one or more optical fibers extend at least partially for transmitting laser light from a laser source to a target location. The probe assembly also comprises a lens housed in the cannula and a protective component at a distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component, and wherein the distal end of the cannula is sealed at a sealing location of the probe assembly.

Apparatus and techniques described herein can include delivery of a surgical laser beam for tissue excision or to facilitate hemostasis. The surgical laser beam can be generated, for example, using an ultrafast laser source. Such an approach can provide non-invasive treatment in relation to, for example, aerodigestive anatomy, such as for treatment of laryngeal, oropharyngeal, bronchial, and oral cavity tissues. Other generally available laser sources and their associated treatments may present various drawbacks making them less suitable for treatment for laryngeal, pharyngeal or bronchial pathologies, and use of the apparatus and techniques described herein can address such drawbacks.

A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).
