An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using “fast-scan-slow-sweep” scanning scheme. A high frequency scanner forms a fast scan line, which is placed by the XY and Z scanners at a location tangential to a parallel of latitude of the surface of the lenticule. The XY and Z scanners then move the scan line in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, and a prism is used to change the orientation of the scan line of the high frequency scanner between successive sweeps. In each sweep, the sweeping speed along the meridian is variable, being the slowest at the edge of the lenticule and the fastest near the apex.

The present disclosure provides, according to some embodiments, methods and systems for selectively reducing, blocking or inhibiting at least part of the neural activity in an organ of a subject. In preferred embodiments, the method and system are used for selectively blocking at least part of the neural activity in a duodenum of a subject in need thereof. According to some embodiments, the selective blocking occurs through use of laser radiation. According to some embodiments, the selective blocking occurs through use of ultrasound energy. According to some embodiments, the selective blocking comprises causing damage to at least part of sensory nerves located within a target area while maintaining functional activity of tissue surrounding the sensory nerves by means of shielding it from the effects of laser radiation. According to some embodiments, the sensory nerves include neurons configured to transmit signals triggered by food passing through the duodenum, such as, but not limited to, neurohormonal signals.

Systems, devices, and methods for treating a skin of a patient with therapeutic laser light via imaging a first skin area of the patient to obtain at least a first image, processing the at least a first image of the first skin area with at least one processor to identify within the first skin area at least one or more target skin areas and a non-target skin area, generating a treatment map of the first skin area based on the identified one or more target skin areas and the non-target skin area, and treating at least a portion of the one or more target skin areas with therapeutic laser light based on the generated treatment map.

Systems and methods for treating a body region are provided herein. A treatment device for treating a body region is provided, and may include a first applicator and a second applicator. The first and second applicators are held on the body region by a belt. The first applicator may include a first magnetic field generating device and a radiofrequency electrode. The second applicator may include a second magnetic field generating device. The first and second magnetic field generating devices may each generate a time-vary magnetic field with a plurality of sequential magnetic impulses to cause muscle contraction in the body region. The radiofrequency electrode may provide radiofrequency waves causing heating of tissue within the body region. The treatment device may further include an energy storage device and a switching device. The switching device my discharge energy from the energy storage device to the first or the second magnetic field generating device to generate the time-vary magnetic field.

An automated laser-surgery system for performing a closed-loop surgical procedure is disclosed. The procedure includes forming a post-procedural goal based on a three-dimensional (3D) image of a surgical site, planning a path for a surgical laser signal based on the post-procedural goal, performing a procedural pass by steering the surgical laser signal along the path, measuring the surface of the surgical site after the procedural pass, updating a model based on the measured effect at the surgical site, and evaluating the success of the procedural pass based on the surface measurement and the post-procedural goal. If necessary, a new path is planned based on the post-procedural goal and the surface measurement a new pass based on that path is performed, and the surface is again measured to evaluate the success of the new pass. These operations are repeated as a closed-loop sequence as many times as necessary to achieve success.

A system includes a focus optic configured to converge an electromagnetic radiation (EMR) beam to a focal region located along an optical axis. The system also includes a detector configured to detect a signal radiation emanating from a predetermined location along the optical axis. The system additionally includes a controller configured to adjust a parameter of the EMR beam based in part on the signal radiation detected by the detector. The system also includes a window located a predetermined depth away from the focal region, between the focal region and the focus optic along the optical axis, wherein the window is configured to make contact with a surface of a tissue.

A catheter includes proximal and distal sections, a shaft coupled between the proximal and distal sections, and optical fibers extending through the shaft and to the distal section of the catheter. The distal section includes a support structure that includes a proximal end, a distal end, reflective elements, and a cap disposed over a portion of the distal end of the support structure. The proximal end includes alignment receptacles. Each of the optical fibers is inserted into corresponding ones of the alignment receptacles and the alignment receptacles are shaped to maintain the optical fibers straight in the support structure. The distal end includes orifices facing different directions. Each of the optical fibers is optically aligned with corresponding ones of the lenses, reflective elements, and orifices such that the optical fibers in the support structure are straight. The cap includes optical ports aligned with the orifices.
