The invention relates to a device (17) for treatment of body tissue, in particular for the permanent occlusion of varicose veins, preferably in the lower limbs, of varicocele and/or of vascular malformations and/or for the use in aesthetic surgeries, preferably laser assisted lipolysis, and/or for tumor treatment by means of laser induced thermotherapy and/or photodynamic therapy, by means of a light diffuser (13) circumferentially and endoluminally irradiating said tissue by laser light energy, said diffuser (13) being connected at its proximal end to a source (10) of laser light energy via a flexible wave guide (12) comprising a fiber optic core (1) covered by an optical cladding (2) having a refractive index smaller than that of the core (1), wherein in the cladding (2) and/or in the core (1) imperfections (18) are provided, designed as recesses and adapted to direct the light, preferably to refract and/or reflect the light propagating within the core (1) and/or its optical cladding (2) in generally radial directions, wherein a cap (7) transparent to the laser light enclosing the distal end of the core (1) and its optical cladding (2) in a fluid tight and/or liquid tight manner is provided. According to the invention the device (17) is characterized in that the outer surface (19) of said optical cladding (2) is fused in the region (A) between said imperfections (18) to the inner surface (21), preferably the inner diameter, of the cap (7) and/or in that the outer surface (19) of said optical cladding (2) extending over a distance in front and/or behind the region (A) provided with the imperfections (18) is fused to the inner surface (21), preferably the inner diameter, of the cap (7).

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

The present disclosure is directed to tools, systems and methods for recontouring/reshaping gum tissue by engaging a consumable tip on a powered tool to abrade/ablate excess or mal-contoured gum tissue to allow better visualization of the tooth/implant structure and reduce the periodontal pockets to provide improved access for cleaning by both the patient and clinician. In some embodiments, the powered tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth/implant surfaces and for recontouring/reshaping gum tissue. The powered tool itself may be constructed to allow the cooling water flow used for operation to be directed to the site where the procedure is carried out for irrigation or to be directed elsewhere at the user's selection to facilitate gum contouring procedures.

A laser system includes a laser diode that, upon activation, selectively produces a continuous wave of laser light or uniformly spaced, intermittent pulses of laser light. The system further includes a laser focuser with a plurality of lenses that focus the laser light produces by the laser diode and direct the laser light to an optical resonator. The optical resonator includes a lasing medium that, when intersected by the laser light from the laser diode, produces a beam of laser light with a wavelength that may be used for therapeutic treatment. The system is operable to produce the therapeutic laser light when the laser diode is operating in either the continuous wave mode or the pulsed mode, without moving components of the system relative to one another.

A thulium fiber laser system can be used to treat tissues based on the ability for quick changes between laser pulses. For example, to treat stones in a tissue, a long pulse having low peak power can be used to create bubbles in front of the stone (calculi), then follow a series of shorter pulses and higher peak power can be used to break the stone. The sequence can be repeated to maintain large bubble formation, with the long pulse characteristics changed to accommodate for the changes in the tissue. A fluorescent sensing assembly can be used to detect the tissue conditions for selecting the conditions of the thulium fiber laser.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

A precision forward-looking image-guided diagnostic and therapeutic surgical probe and needle insert for microsurgery in support of imagery, neurology, neurosurgical procedures, and ophthalmic surgical applications comprising an introducer needle (stylet), a fiber carrier, a therapeutic conduit, and a spirographic method for scanning a target and associated algorithms to create and render a reconstructed image for display to a physician in real-time or near real-time. The probe implements Optical Coherence Tomography (OCT) to provide high-resolution extended imagery of an intended therapeutic or target tissue. A separate therapeutic conduit provides surgical access for therapeutic devices such as a cutting or ablation laser, an RF electrode for locally heating tissue, a lumen for local injection of neurolytics/paralytics, placement of electrodes for neuromodulation, and deployment of a micro-endoscopic imaging tool. A third working channel supports the delivery of neurolytic and other fluids.

This disclosure relates to various systems and methods related to preventative laser-based treatment of a dental tissue; for example, to prevent a patient from forming cavities. In some instances, a laser-based treatment system can generate a laser beam pulse with a fluence profile at a treatment site that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. In some instances, the laser-based treatment system can direct the laser beam to various locations within a treatment site according to a temporal and/or spatial pattern, that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. Many other systems and techniques for preventative and other laser-based treatment are also described.
