A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5″ C.

The disclosure pertains to biotransducers and particularly to methods and apparatus for treating medical conditions and ailments using light therapy biotransducers.

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).

A light filter (100) includes at least one layer of binder matrix (110) and a multitude of transparent crystals (120). The multitude of transparent crystals (120) are irregularly and laterally dispersed in the at least one layer of binder matrix (110), such that light passing through the light filter (100) is separated into different wavelengths and polarized into different orientations.

Summary

The therapeutic device of the invention consists of a support to be placed on the skin of a patient and made of specific nanocrystals, which when properly activated, produce electromagnetic emissions that have beneficial effects on inflammatory, painful pathologies, and neuro-muscular and postural modulations of the patient.

There is provided a phototherapy apparatus, in which the therapeutic light is delivered through one or more massage components. The massage component provides mechanical massage to the subject biological tissue and modifies the properties of the subject tissue in thickness, density, etc. to facilitate the absorption of the therapeutic light and enhance the effect of the phototherapy procedure. The light source of the phototherapy apparatus is actively cooled by a synthetic jet cooler.

Periodontal disorders such as disorders associated with a dental implant are treated. An average power for a laser is selected via a user interface on a tablet, along with a set of permissible laser parameters provided in response to the selected average power. A gingival trough or flap is created around the implant with the laser. Infected tissue is selectively ablated or denatured via photothermolysis, and a pocket is lased around the affected implant. Marginal tissues are compressed against the implant.

Periodontal disorders such as disorders associated with a dental implant are treated with a laser where an average laser power along with other laser parameters provide particular settings for the treatment, the treatment including one or more of creating a gingival trough or flap around the implant, ablating or denaturing infected tissue via photothermolysis, lasing a pocket around the affected implant, and compressing marginal tissues against the implant.

The device includes a laser source (7) adapted to emit a laser radiation at a wavelength between around 620 nm and around 750 nm, and a handpiece (5). The handpiece in turn includes an applicator (11) with a contact surface with the epidermis defining a window (11.1) for the passage of a laser beam (F) toward the epidermis (E) of a subject to be treated. A waveguide (10) conveys the laser radiation from the laser source (7) to a scanning system (17) of the handpiece.

An optical therapeutic device comprising a front body portion, a light source provided in said front body portion, a spherical, translucent quartz lens provided in front of said light source, a bezel provided on said front body portion and configured to hold said spherical, translucent quartz lens such that a portion of the quartz lens protrudes outside the rim of the bezel. Also described is a method of using the device to apply light stimulation to acupuncture points of a human or animal body and a method for manufacturing the device.
